Black masterbatch Food grade Food packaging materials PET

Product Detail

Product Description
Using a unique process, in which polymer additives and environmentally friendly carbon black are pre-dispersed and then plasticized and melted with the resin.

It is widely used in PET thermoforming and injection molding applications. Features include low addition rate, high blackness, high gloss, high temperature resistance, excellent dispersibility and coloring power, while maintaining the original physical properties of the plastic products.

Features
● Good heat resistance and stability
● High coloring power, low addition rate
● Minimal effect on material properties
● High carbon black concentration with superior dispersion

Applications
● PET thermoforming
● PET injection molding
