PET Resin, Brand Name : WANKAI, Density : 75, Purity : 90%

PET (Polyethylene Terephthalate) Resin is a thermoplastic polymer belonging to the polyester family. It is synthesized through the polycondensation of terephthalic acid (PTA) or dimethyl terephthalate (DMT) with monoethylene glycol (MEG).

It is widely used in bottle manufacturing, food packaging, films, fibers, and engineering components due to its excellent strength, clarity, barrier properties, and recyclability.
