White plastic should stay white. Yet many products turn cream or yellow after processing, storage or months of use. For importers, distributors and brand owners, yellowing means complaints, returns and lost repeat orders.
Anti-yellowing white masterbatch solves this problem at the source. It combines titanium dioxide (TiO₂), a matched carrier resin and protective additives in one easy-to-dose pellet. This guide explains what causes yellowing, how anti-yellowing masterbatch works, which carrier suits PE, PP, ABS and PET, and what to check before you buy from a Chinese manufacturer.
Debao has focused only on white masterbatch since 2015. We supply TiO₂ loadings from 20% to 75% on PE, PP, PET, PS and ABS carriers, with an annual output of 45,000 tons.
A standard white masterbatch gives whiteness and opacity. An anti-yellowing grade does the same job and adds protection against the reactions that cause color drift. The market also calls it non-yellowing white masterbatch. Names differ between suppliers, so always check the formulation, not just the label.
A typical formulation includes:
• Rutile TiO₂ for whiteness, opacity and UV scattering
• Carrier resin matched to your base polymer (PE, PP, ABS or PET)
• Antioxidants and processing stabilizers to resist heat damage
• UV absorbers or HALS where outdoor exposure is expected (by grade)
• Dispersing agents for even color and fewer streaks
• Heat during processing. High melt temperature, long residence time or high shear can oxidize the polymer and its additives.
• UV light. Sunlight starts photo-oxidation, which discolors the surface over time.
• Additive by-products. Some phenolic antioxidants form colored compounds, especially when goods sit near exhaust fumes in warehouses.
• TiO₂ quality. Low-grade or poorly treated TiO₂ can speed up surface degradation outdoors.
• Poor dispersion. Agglomerates create uneven color and weak spots.
• Recycled content and contamination. Regrind, residual catalyst and mixed resins often carry a yellow tint.
• Storage conditions. Heat, humidity and long storage can shift color before the product reaches your customer.
Hot, sunny regions make the problem worse. Buyers in the Middle East, Africa, South Asia, Australia and South America often see color change sooner than buyers in cooler climates.
1. Rutile TiO₂ gives bright white and blocks part of the UV light. Surface-treated grades reduce photoactivity.
2. Antioxidants and processing stabilizers protect the polymer from heat while it melts and flows.
3. UV absorbers and HALS handle the light that still reaches the polymer. We add them to selected grades for outdoor use.
4. Fine dispersion creates uniform color and a stable surface.
5. A matched carrier blends with your base resin without streaks or gels.
Some formulas also include optical brighteners. They improve first-look whiteness by shifting reflected light toward blue, which masks a slight yellow tint. They do not stop degradation, so treat them as an add-on, not a replacement for stabilizers.
No masterbatch stops yellowing forever. It slows the process. Real results depend on resin, thickness, dosage, climate and exposure time, so always test a sample before a bulk order.
Grades may vary by project. Please confirm exact values on the technical data sheet before you order.
Buyers also ask about these points:
• TiO₂ source and equipment: we work with established TiO₂ producers such as Lomon Billions and Tronox, and we use Farrel Pomini compounding equipment.
• Quality control: more than 20 test steps run on our white masterbatch, and our lab checks color, MFI and heat stability batch by batch.
• Compliance: our products are produced to meet RoHS and REACH requirements. Selected grades are FDA compliant. Compliance depends on the grade and the final application.
• Customization: our R&D team can adjust TiO₂ loading, carrier resin, MFI, tint and additives for OEM projects.
Anti-yellowing formulas are matched to each project. Tell us your resin, process and target market, and we will recommend a suitable stabilizer package.
• Blow molding: bottles, drums and containers
• Pipes, sheets and profiles: extruded parts used in construction and infrastructure
• Rotomolded products: water tanks and large hollow items
Our PE White Masterbatch range runs from 30% to 75% TiO₂. For example, 70% grades suit food packaging, consumer goods and industrial packaging, while 60% grades suit cost-focused courier bags. If your PE product stays outdoors, tell us the exposure time so we can add a UV package.
• Injection molding: caps, closures, housings, kitchenware and storage boxes
• Film: BOPP and CPP film for labels, lamination and packaging
• Woven bags: fertilizer, grain and cement sacks that often sit outdoors
• Nonwoven and fiber: hygiene products and fabrics, where fine dispersion keeps spinning stable
Our PP White Masterbatch range covers 30% to 70% TiO₂, with specific grades for BOPP film, CPP film, injection molding, nonwoven fabric and fibers. Share your process and we will suggest a starting grade.
ABS white masterbatch is made for injection molding and extrusion. We offer TiO₂ loadings from 40% to 70%, so you can balance opacity, surface finish and cost. Dry the ABS resin before processing, and avoid long residence time in the barrel. Both steps reduce heat-related color shift.
We offer PET white masterbatch with 60% and 70% TiO₂. The 70% grade gives the highest opacity and brightest white for premium films and bottles. The 60% grade suits cost-sensitive, high-volume products. Typical uses include opaque bottles and containers, films and sheets, thermoformed products, and polyester fibers.
• Appliances: panels, covers and housings for home and small appliances (ABS, PP)
• Packaging: food packaging, consumer goods packaging, industrial packaging, bags, bottles and labels (PE, PP, PET)
• Automotive: interior trim and panels (PP, ABS)
• Toys and leisure goods: bright white parts with a clean surface (ABS, PP)
• Daily goods: kitchenware, storage boxes, caps and closures (PP, PE)
• Agriculture and hygiene: mulch film, nonwoven fabrics and hygiene products (PE, PP)
For food contact or medical items, confirm compliance documents for the exact grade and your target market before you place an order.
• Standard white masterbatch is built for whiteness and hiding power. It suits indoor products, short service life and single-use packaging.
• Anti-yellowing white masterbatch adds stabilizers to slow color drift during processing, storage and use. It suits white appliances, long-life goods, light-colored parts and products shipped to hot climates.
The price difference is usually small compared with the cost of one yellowed batch. But do not pay for protection you do not need. If a product is used indoors and replaced quickly, a standard grade is often enough. If sunlight is the main risk, read our guide to UV resistant white masterbatch for more detail.
1. Mix evenly. Blend the masterbatch with the base resin, or use a dosing unit.
2. Control temperature. Stay within the range advised for your carrier and base resin. If you run at 200 °C or above, ask about heat-stable grades.
3. Keep pellets dry. This matters most for PET and ABS. Moisture causes bubbles, surface defects and color shift.
4. Limit residence time. Avoid long stops with material sitting in a hot barrel.
5. Check color properly. Use the same light source for every approval, and track ΔE and yellowness index if you can.
6. Change one variable at a time during trials.
7. Store correctly. Keep bags in a cool, dry place and reseal opened bags.
Use this checklist when you compare grades and suppliers:
1. Define the end use. Note indoor or outdoor use, expected service life, climate and thickness.
2. Identify the yellowing source. Is it heat, light, storage or recycled content? The answer decides the stabilizer package.
3. Match the carrier. Use PE for PE, PP for PP, ABS for ABS and PET for PET.
4. Set TiO₂ loading and dosage. Balance opacity, cost and processing.
5. Check MFI and processing temperature. Confirm they fit your machine and process.
6. Confirm compliance. Decide whether you need RoHS, REACH, FDA or EU food contact documents.
7. Test a sample. Check color, dispersion and surface finish before you place a bulk order.

What Is Anti-Yellowing White Masterbatch?
Anti-yellowing white masterbatch is a pelletized concentrate that helps white plastic keep its color. It contains rutile TiO₂ pigment, a carrier resin and a stabilizer package. You blend it with natural resin during film blowing, injection molding, extrusion, blow molding or fiber spinning.A standard white masterbatch gives whiteness and opacity. An anti-yellowing grade does the same job and adds protection against the reactions that cause color drift. The market also calls it non-yellowing white masterbatch. Names differ between suppliers, so always check the formulation, not just the label.
A typical formulation includes:
• Rutile TiO₂ for whiteness, opacity and UV scattering
• Carrier resin matched to your base polymer (PE, PP, ABS or PET)
• Antioxidants and processing stabilizers to resist heat damage
• UV absorbers or HALS where outdoor exposure is expected (by grade)
• Dispersing agents for even color and fewer streaks
Why Does White Plastic Turn Yellow? Main Causes
Yellowing is usually a chemical change inside the polymer, not a pigment fault. These are the most common causes:• Heat during processing. High melt temperature, long residence time or high shear can oxidize the polymer and its additives.
• UV light. Sunlight starts photo-oxidation, which discolors the surface over time.
• Additive by-products. Some phenolic antioxidants form colored compounds, especially when goods sit near exhaust fumes in warehouses.
• TiO₂ quality. Low-grade or poorly treated TiO₂ can speed up surface degradation outdoors.
• Poor dispersion. Agglomerates create uneven color and weak spots.
• Recycled content and contamination. Regrind, residual catalyst and mixed resins often carry a yellow tint.
• Storage conditions. Heat, humidity and long storage can shift color before the product reaches your customer.
Hot, sunny regions make the problem worse. Buyers in the Middle East, Africa, South Asia, Australia and South America often see color change sooner than buyers in cooler climates.
How Does Anti-Yellowing White Masterbatch Work?
A good anti-yellowing white masterbatch works in layers. Each layer handles one cause:1. Rutile TiO₂ gives bright white and blocks part of the UV light. Surface-treated grades reduce photoactivity.
2. Antioxidants and processing stabilizers protect the polymer from heat while it melts and flows.
3. UV absorbers and HALS handle the light that still reaches the polymer. We add them to selected grades for outdoor use.
4. Fine dispersion creates uniform color and a stable surface.
5. A matched carrier blends with your base resin without streaks or gels.
Some formulas also include optical brighteners. They improve first-look whiteness by shifting reflected light toward blue, which masks a slight yellow tint. They do not stop degradation, so treat them as an add-on, not a replacement for stabilizers.
No masterbatch stops yellowing forever. It slows the process. Real results depend on resin, thickness, dosage, climate and exposure time, so always test a sample before a bulk order.

Anti-Yellowing White Masterbatch for PE (Film, Pipe, Blow Molding)
PE is the most common carrier for packaging and agriculture products. Thin PE film shows yellowing quickly, because heat on the extrusion line and sunlight during storage both act on a very thin layer.Where PE buyers use it
• Blown film and bags: food packaging, courier bags and shopping bags• Blow molding: bottles, drums and containers
• Pipes, sheets and profiles: extruded parts used in construction and infrastructure
• Rotomolded products: water tanks and large hollow items
Our PE White Masterbatch range runs from 30% to 75% TiO₂. For example, 70% grades suit food packaging, consumer goods and industrial packaging, while 60% grades suit cost-focused courier bags. If your PE product stays outdoors, tell us the exposure time so we can add a UV package.
Anti-Yellowing White Masterbatch for PP (Injection Molding, Woven Bags, Fiber)
PP reacts strongly to heat and UV light, so stabilization matters. A PP carrier also gives the best melt-flow match with PP base resin, which helps avoid streaks.• Injection molding: caps, closures, housings, kitchenware and storage boxes
• Film: BOPP and CPP film for labels, lamination and packaging
• Woven bags: fertilizer, grain and cement sacks that often sit outdoors
• Nonwoven and fiber: hygiene products and fabrics, where fine dispersion keeps spinning stable
Our PP White Masterbatch range covers 30% to 70% TiO₂, with specific grades for BOPP film, CPP film, injection molding, nonwoven fabric and fibers. Share your process and we will suggest a starting grade.
Anti-Yellowing White Masterbatch for ABS Products
ABS contains a butadiene rubber phase, which makes it sensitive to heat and light. White ABS parts, such as appliance panels and electronics housings, can turn yellow in use if the formulation is not protected.ABS white masterbatch is made for injection molding and extrusion. We offer TiO₂ loadings from 40% to 70%, so you can balance opacity, surface finish and cost. Dry the ABS resin before processing, and avoid long residence time in the barrel. Both steps reduce heat-related color shift.
Anti-Yellowing White Masterbatch for PET (Bottles, Sheets, Fiber)
PET melts above 250 °C, so processing is hot. Moisture and long residence time at high temperature can cause degradation and a yellow tint. This makes dry pellets and stable temperature control essential.We offer PET white masterbatch with 60% and 70% TiO₂. The 70% grade gives the highest opacity and brightest white for premium films and bottles. The 60% grade suits cost-sensitive, high-volume products. Typical uses include opaque bottles and containers, films and sheets, thermoformed products, and polyester fibers.
Common Applications: Appliances, Packaging, Automotive, Toys & Daily Goods
Anti-yellowing grades help most where white color is part of the product value. Common uses include:• Appliances: panels, covers and housings for home and small appliances (ABS, PP)
• Packaging: food packaging, consumer goods packaging, industrial packaging, bags, bottles and labels (PE, PP, PET)
• Automotive: interior trim and panels (PP, ABS)
• Toys and leisure goods: bright white parts with a clean surface (ABS, PP)
• Daily goods: kitchenware, storage boxes, caps and closures (PP, PE)
• Agriculture and hygiene: mulch film, nonwoven fabrics and hygiene products (PE, PP)
For food contact or medical items, confirm compliance documents for the exact grade and your target market before you place an order.
Anti-Yellowing vs Standard White Masterbatch: What’s the Difference?
Both give color and opacity. The difference is protection.• Standard white masterbatch is built for whiteness and hiding power. It suits indoor products, short service life and single-use packaging.
• Anti-yellowing white masterbatch adds stabilizers to slow color drift during processing, storage and use. It suits white appliances, long-life goods, light-colored parts and products shipped to hot climates.

If a product is used indoors and replaced quickly, a standard grade is often enough. If sunlight is the main risk, read our guide to UV resistant white masterbatch for more detail.
TiO₂, Optical Brightener or UV Stabilizer: Which Solves Yellowing?
Each additive solves a different problem. Most buyers need a combination.Rutile TiO₂
TiO₂ gives whiteness and opacity, and it scatters part of the UV light. Grade and surface treatment matter, because two products with the same TiO₂ percentage can age very differently.Optical brightener
It boosts first-look whiteness and hides a slight yellow tint. It does not protect the polymer, and its effect can fade over time.UV absorbers and HALS
These protect the polymer from sunlight. Absorbers turn UV energy into heat, and HALS trap the free radicals that start breakdown. They matter most for outdoor products.Antioxidants and heat stabilizers
They protect the polymer during melting and processing. Choose them first if yellowing appears right after molding or extrusion.Recommended Dosage and Processing Guide
Most buyers start at about 1% to 5% masterbatch, then adjust after a trial. The final dosage depends on TiO₂ loading, product thickness and target whiteness. Thin film with high opacity needs may need more. Thick parts may need less.1. Mix evenly. Blend the masterbatch with the base resin, or use a dosing unit.
2. Control temperature. Stay within the range advised for your carrier and base resin. If you run at 200 °C or above, ask about heat-stable grades.
3. Keep pellets dry. This matters most for PET and ABS. Moisture causes bubbles, surface defects and color shift.
4. Limit residence time. Avoid long stops with material sitting in a hot barrel.
5. Check color properly. Use the same light source for every approval, and track ΔE and yellowness index if you can.
