Pet Bottle Grade Pet Resin Hainan Yisheng Factory Directly Supply

Product Description

Product Description Pet is an opalescent or light yellow highly crystalline polymer with smooth and glossy surface. It has good creep resistance, fatigue resistance, wear resistance and dimensional stability, small wear and high hardness. It has the largest toughness in thermoplastic plastics: good electrical insulation performance, little influence by temperature, but poor corona resistance. It is non-toxic, weather resistant, chemical resistant, stable, low water absorption, weak acid and organic solvent resistance, but not resistant to hot water immersion and alkali.PET resin has high glass transition temperature, slow crystallization rate, long molding cycle, large molding shrinkage, poor dimensional stability, brittle molding and low heat resistance.
