Polyester chips usually refer to polyester raw materials produced by polymerization, which are generally processed into flaky particles of about 4*5*2 mm. The process routes of polyester production include direct esterification (PTA) and transesterification (DMT). PTA process has the advantages of low raw material consumption and short reaction time, and has become the main process and preferred technical route of polyester since 1980s. The uses of polyester now include fibers, various containers, packaging materials, films, films, engineering plastics and other fields.

1.According to the composition and structure, it can be divided into: blending, copolymerization, crystallization, liquid crystal, annular polyester chips, etc.
2.According to the performance, it can be divided into: colored, flame retardant, antistatic, hygroscopic, anti-pilling, antibacterial, whitening, low melting point, tackified (high viscosity) polyester chips, etc.
3.According to the purpose, it can be divided into fiber grade polyester chips, bottle grade polyester chips and film grade polyester chips (mainly due to different process indexes). Fiber-grade polyester chips can be divided into super-bright (bright), bright, semi-dull and (full) dull polyester chips according to the different content of matting agent tio2. There are also cationic polyester chips.
