What is the melting point of PET plastic film?
PET plastic is the abbreviation of Polyethylene terephthalate in English, referred to as PET or PETP. Polybutylene terephthalate mainly consists of polyethylene terephthalate, two ester PET and polybutylene terephthalate two PBT. Polyethylene terephthalate is also commonly called polyester resin. It is a condensation of terephthalic acid with ethylene glycol and is collectively referred to as thermoplastic polyester, or saturated polyester, with PBT.
The melting point of PET plastic film is generally about 260 degrees.
PET has a high molecular structure and a certain crystalline orientation, so it has high film forming ability and plasticity. PET plastic has good optical properties and weather resistance, and amorphous PET plastic has good optical transparency. In addition, PET plastic has excellent wear resistance, friction and dimensional stability and electrical insulation. PET bottles are widely used because of their high strength, good transparency, non-toxic, impermeable, light quality and high production efficiency. PBT and PET molecular chain structure similar, most of the same nature, but the main chain from two methylene into four, so the molecules are more supple, processing performance is better.
