100% Virgin Food Grade Sinopec PET Resin for Raw Materials
sinopec pet resin
PET plastic is Polyethylene terephthalate : referred to as PET or PETP. Poly-terephthalic acid-based plastic, mainly including polyethylene terephthalate PET and polybutylene terephthalate PBT. Polyethylene terephthalate also known as polyester resin. It is a condensate of terephthalic acid and ethylene glycol, together with PBT, referred to as thermoplastic polyester, or saturated polyester.
PET Characteristic: is milky white or light yellow highly crystalline polymer, the surface smooth and shiny.
Anti-fatigue, good abrasion resistance, small wear and high hardness, with the maximum toughness of thermoplastic; electrical insulation performance, affected by temperature, but poor resistance to corona. Non-toxic, weatherability, anti-chemicals, good stability, high moisture absorption, drying before molding is necessary. Weak acid and organic solvents, but not hot water immersion, not alkali.
PET Plastic Molding processing: Can be injection molding, extrusion, blow molding, coating, bonding, machining, plating, vacuum metallization, printing.
