Polyester chips usually refers to the polyester raw materials obtained from the polymerization production is generally processed into about 4 * 5 * 2 mm or so sheet particles. 1. According to the composition and structure can be divided into: blended, copolymerization, crystalline, liquid crystal, cyclic polyester chips and so on; 2. According to the performance can be divided into: coloring, flame retardant, antistatic, moisture absorption, anti-pilling, antibacterial, whitening, low melting point, viscosity (high viscosity) polyester chips, etc.; 3. According to the use 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 glossy (big glossy), glossy, semi-matte, (full) matte polyester chips. There are also cationic polyester chips. Polyester applications now include fibers, various types of containers, packaging materials, films, films, engineering plastics, and other fields.
