Plastic parts often fail the white test long before they fail the strength test. A bag, crate or appliance housing leaves the machine with a yellow tint, gray streaks or weak opacity. In most cases, the cause is heat. The pigment package could not handle the processing temperature.
That is why buyers search for heat resistant white masterbatch. It keeps color stable when resin runs hot, and it keeps TiO2 evenly spread through the melt. Debao is a white masterbatch manufacturer in Jiangyin, Jiangsu, China. We focus on white masterbatch only, and we supply overseas importers, distributors, OEM buyers and plastics factories.
This guide explains what heat resistant white masterbatch is, how it performs, where it fits, and what to check before you place an order.
Heat resistant white masterbatch uses a formulation built to stay stable at higher melt temperatures and longer residence times. It resists yellowing, keeps its whiteness and holds dispersion quality when the process runs hot. Standard grades can lose brightness or develop odor and specks under the same conditions.
For a factory, this means fewer rejected parts, fewer color complaints and a wider processing window.
• Stable whiteness: Formulated to keep a clean white tone during hot processing.
• High dispersion: Pigment is spread evenly, which supports a smooth surface and consistent color across batches.
• Wide concentration range: TiO2-based white masterbatch from 20% to 75% concentration.
• Multiple carrier resins: PE, PP, PET, PS and ABS carriers, matched to your base polymer.
• Custom tuning: Whiteness, opacity, melt flow index and additive package can be adjusted to your process.
• White masterbatch focus. We do not spread our effort across many product lines. White is our core product.
• Production scale. Our annual output of white masterbatch is 45,000 tons, which supports regular and repeat orders.
• Equipment and control. We use advanced production equipment, a professional R&D team and strict quality control.
• Export experience. We attend international exhibitions such as K 2025 in Düsseldorf and Chinaplas 2025, and we have operated for more than ten years.
• Direct communication. You talk to the manufacturer, not a trading layer, about specifications, samples and delivery.
Heat resistance matters most in three situations:
• High barrel or die temperatures
• Long residence time, for example thick parts or slow cycles
• Regrind and recycled resin that have already seen heat once
The safe temperature window differs by grade. We confirm the recommended processing range for each grade on its technical data sheet, so please share your resin type, process and melt temperature before you order.
An anti-yellowing white masterbatch limits this in several ways:
• It uses a thermally stable carrier and additive package.
• It disperses TiO2 evenly, so shear and heat spread more smoothly through the melt.
• It reduces the risk of odor, smoke and specks at higher temperatures.
Heat is not the only cause of yellowing. Outdoor products also need protection from sunlight. If your parts face weather exposure, look at our UV resistant white masterbatch option together with heat stability.
The table below shows the main parameters of our white masterbatch range. Values that vary by grade are confirmed on the data sheet or in the quotation.
• PP: Common in containers, woven bags, caps and household items. Our PP white masterbatch range covers these uses.
• PE: Used in film, shopping bags, crates, tanks and agriculture film.
• PET: Used for packaging, preforms and fiber, where temperatures run higher.
• PS: Used in disposable items and thermoformed packaging.
• ABS: Used in appliance housings, automotive interior parts and consumer goods.
For this process, buyers should check dispersion, melt flow match and thermal stability together. Our white masterbatch for injection molding page explains how we approach these parts, from household items to technical components.
For film, good dispersion and a well-matched carrier give a smooth surface and steady opacity. This matters for plastic bags, shopping bags, agriculture mulch film and packaging film. For extrusion coating, please send us your line temperature and substrate so we can recommend a suitable grade.
• Household and consumer goods: Crates, storage boxes, buckets, housewares and small appliance parts.
• Automotive: Interior plastic parts that need stable white or light tones.
• Construction and infrastructure: Water tanks, pipes and profiles.
• Agriculture: Mulch film and other agricultural film.
If your product is not listed, send us a drawing, sample or process description. We will review it.
For regulated markets, compliance documents matter. Debao supplies ROHS certified white masterbatch. If your project also needs food-contact or other regional documents, tell us the target market and end use. We will confirm what documentation we can provide before you commit.
When you compare suppliers, ask each one for:
• A technical data sheet and a recent certificate of analysis
• Compliance documents for your target market
• A sample you can test on your own line
• Batch-to-batch consistency records
• TiO2 concentration and whiteness or tone
• Carrier resin and melt flow index
• Additives such as anti-yellowing, UV or processing aids
• Packaging type and labeling for export
Minimum order quantity, price and lead time depend on the grade and volume. Send us your requirement, and we will reply with a clear quotation. We support export shipments to importers and factories worldwide, including FOB terms from China.
A simple ordering path works best: share your application, test a sample, approve the grade, then place a trial order before moving to regular supply.
If your process runs cool and your parts are simple, a standard grade may be enough. If you see yellowing, specks or color drift, a heat-stable grade is the better choice.
A: It depends on the grade and the carrier resin. Polyolefin processing often runs around 160°C to 280°C, and some resins run hotter. Tell us your resin and melt temperature, and we will recommend a grade and confirm the range on the data sheet.
Q: Does heat resistant white masterbatch stop yellowing completely?
A: No masterbatch can stop it completely under every condition. A heat-stable formulation greatly lowers the risk. Resin quality, processing settings and light exposure also affect final color.

This guide explains what heat resistant white masterbatch is, how it performs, where it fits, and what to check before you place an order.
What Is Heat Resistant White Masterbatch?
White masterbatch is a concentrate of titanium dioxide (TiO2), a carrier resin and processing additives. You mix it with natural resin at a set ratio to make white plastic parts.Heat resistant white masterbatch uses a formulation built to stay stable at higher melt temperatures and longer residence times. It resists yellowing, keeps its whiteness and holds dispersion quality when the process runs hot. Standard grades can lose brightness or develop odor and specks under the same conditions.
For a factory, this means fewer rejected parts, fewer color complaints and a wider processing window.

Heat Resistance and Processing Temperature Range
Processing temperature depends on the carrier resin and the process. Polyolefin extrusion and injection molding often run in a range of roughly 160°C to 280°C. PET and engineering resins run hotter. Extrusion coating can push temperatures higher still.Heat resistance matters most in three situations:
• High barrel or die temperatures
• Long residence time, for example thick parts or slow cycles
• Regrind and recycled resin that have already seen heat once
The safe temperature window differs by grade. We confirm the recommended processing range for each grade on its technical data sheet, so please share your resin type, process and melt temperature before you order.
How Does Heat Resistant White Masterbatch Prevent Yellowing at High Temperatures?
Yellowing during processing usually comes from thermal degradation of the carrier, the resin or the additives. High heat breaks polymer chains and creates color bodies. Poor dispersion makes it worse, because agglomerated pigment traps heat and shear.An anti-yellowing white masterbatch limits this in several ways:
• It uses a thermally stable carrier and additive package.
• It disperses TiO2 evenly, so shear and heat spread more smoothly through the melt.
• It reduces the risk of odor, smoke and specks at higher temperatures.
Heat is not the only cause of yellowing. Outdoor products also need protection from sunlight. If your parts face weather exposure, look at our UV resistant white masterbatch option together with heat stability.
TiO2 Content, Dispersion and Thermal Stability
TiO2 Content
Higher TiO2 content gives more opacity per gram, so you can use a lower dosage. Our range runs from 20% to 75%. Lower concentrations suit thin, simple products. Higher concentrations suit applications that need strong coverage at a lower let-down ratio.Dispersion Quality
Poor dispersion shows up as streaks, gels, specks and film breaks. High dispersion white masterbatch helps avoid these problems. It also improves surface gloss and keeps color consistent from batch to batch.Melt Flow Index Matching
The masterbatch carrier should flow similarly to your base resin. A mismatch causes uneven mixing. A low melt flow index white masterbatch fits resins with low MFI, such as many blow molding and extrusion grades. Tell us your resin grade and MFI, and we will match the carrier.Technical Specifications

Our white masterbatch for injection molding page explains how we approach these parts, from household items to technical components.
Heat Resistant White Masterbatch for Extrusion Coating and Film
Film and extrusion lines run for long hours. Any weakness in the masterbatch shows up as die lines, gels, smoke or film breaks. Extrusion coating runs especially hot, so heat stability matters even more.For film, good dispersion and a well-matched carrier give a smooth surface and steady opacity. This matters for plastic bags, shopping bags, agriculture mulch film and packaging film. For extrusion coating, please send us your line temperature and substrate so we can recommend a suitable grade.
