PS White Masterbatch


High Brightness & Opacity for Polystyrene Applications


At Debao, we specialize in white masterbatch solutions tailored to different plastic carrier resins. Among them, PS white masterbatch is designed specifically for use with polystyrene-based products, offering excellent dispersion, high opacity, and brilliant whiteness.


What Is Polystyrene (PS)?


Polystyrene (PS) is a synthetic aromatic polymer made from the monomer styrene. It is widely used for applications requiring rigidity, clarity, and low cost.


Structural Formula of PS:


The repeating unit of polystyrene has the following structure:
–[CH₂–CH(C₆H₅)]–ₙ


This means that every repeating unit consists of a vinyl group (–CH₂–CH–) attached to a phenyl ring (C₆H₅). The structure gives PS its characteristic rigidity and transparency.Major Applications of Polystyrene (PS)

1. Packaging Industry
  • Food packaging
  • Protective packaging
  • Cosmetic containers

2. Construction Sector
  • Thermal insulation: In walls, roofs, and foundations.
  • Acoustic insulation: To reduce noise transmission.
  • Lightweight fill material: In road and bridge construction.​ 

3. Consumer Goods
Polystyrene is prevalent in manufacturing various household items:
  • Appliance housings: Such as those for refrigerators and air conditioners.
  • Disposable products: Like razors and plastic cups.
  • Toys and recreational items: Due to its moldability and cost-effectiveness.​

4. Medical Applications
Thanks to its clarity and ease of sterilization, polystyrene is used in:
  • Laboratory ware: Petri dishes, test tubes, and culture trays.
  • Medical device components: Where transparency and rigidity are required 

5. Electronics and Electrical Components
Polystyrene's insulating properties make it suitable for:
  • Insulation of electrical components: Such as in televisions and computers.
  • Housing for electronic devices: Due to its rigidity and ease of molding.​

6. Optical Applications
General Purpose Polystyrene (GPPS) is valued for its clarity:
  • Lighting fixtures: Diffusers and covers.
  • Display cases: Where transparency is essential.​ 

These diverse applications highlight polystyrene's adaptability and significance in modern manufacturing and product design
