Film Grade Silica Polyester Chips Category: PET Chips Raw Materials: PTA (Purified Terephthalic Acid) EG (Ethylene Glycol) Silica Grade: Film Grade Form: Dull MATT (Silica) PET Chips are specifically designed to enhance the performance of release films and serve as a filler or additive for matte films. These chips are produced by blending silica nanoparticles with polyester resins during the manufacturing process. The inclusion of silica improves the overall properties and functionalities of the polyester chips, making them highly suited for applications where a matte finish or enhanced release characteristics are desired.
