This machine is suitable for producing PP/PS/PET sheet. It extrudes granule to sheet which is used for producing different kind of plastic cups, food containers, trays, dishes, bowls, trays, lids, etc.
Polybutylene terephthalate, the chemical formula is COC6H4COOCH2CH2O. (English: Polyethylene terephthalate, referred to as PET), synthesized by transesterification of terephthalic acid two to ethylene glycol or terephthalic acid and ethylene glycol, then polycondensation of terephthalate. It is a crystalline saturated polyester. It is a milky white or light yellow, highly crystalline polymer with smooth and glossy surface. It is a common kind of resin in life, which can be divided into APET, RPET and PETG.
