The injection techniques of poly terephthalic acid alcohol ester (PET)

The chemical name of PET is poly terephthalic acid alcohol ester, also called polyester. At present, GF-PET is used by most clients. PET injection molding parts are mostly used in the bottle preform products

PET plastic has a good rheological property in molten condition and pressure has more effects on viscosity than temperature does. Therefore, we change the rheological property mainly from the pressure.

PET Plastic drying

Due to PET macromolecule contains an aliphatic base, it has certain hydrophilicity. The aggregate is very sensitive to water when it’s at a high temperature. When the water content exceeds the limit, the molecular weight of the PET material will drop […]
