Polyethylene Glycol Terephthalate WK PET 821

WK-821 is a PET polymer material. Mainly used in edible oil, wine, medicine, sparkling beverage bottles, APET sheets, etc.

821 is a kind of Polyethylene Glycol Terephthalate polymer material. it can be mainly used in edible oil, wine, medicine, sparkling beverage bottles, APET sheets, etc.

Polyethylene Glycol Terephthalate is synthesized by ester exchange of dimethyl terephthalate and ethylene glycol or esterification of terephthalic acid and ethylene glycol, and then synthesizes bishydroxyethyl terephthalate. Produced by polycondensation reaction. It is a crystalline saturated polyester. It is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It is a common resin in life and can be divided into APET, RPET and PETG.

Polyethylene Glycol Terephthalate has excellent physical and mechanical properties, its operating temperature can reach 120°C, and Polyethylene Glycol Terephthalate has excellent electrical insulation. Even at high temperatures and high frequencies, its electrical properties are still good, but its corona resistance is poor. Creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good.
