Polyester Chip Classification: film grade, fiber grade, bottle grade polyester chips

Abstract: Membrane grade, fiber grade, bottle grade polyester chips

1, according to the composition and structure: blending, copolymerization, crystallization, liquid crystal, polyester chips and other loop;

2, according to the performance can be divided into: colorant, flame retardant, antistatic, moisture absorption, anti-pilling, anti-bacterial, whitening, low melting point tackifier (high viscosity) PET chip;

3, according to the purpose can be divided into: fiber grade polyester chips, bottle grade polyester chips, film grade polyester chips (mainly different process indicators).

Fiber grade polyester chips according to which the content of matting agent TiO2 can be divided into: Super bright (bright), bright, semi-dull, (all) extinction polyester chips. There are also cationic polyester chips and so on.   

(1) ultra-bright polyester chips: refers to no TiO2, the appearance of standard colorless transparent particles;

(2) bright polyester chips: containing 0.1% TiO2, translucent particles;

(3) semi-dull polyester chips: containing 0.3 to 0.5% TiO2, milky white or gray particles;

(4) full extinction polyester chips: containing 2.5% TiO2;

(5) cationic polyester chips: for the transparent (yellowish) particles, particles even;

(6) high absorbent polyester chips: PET resin by adding a specific additive (pore agent) made;
