A plastic container material

The name of PET polyethylene terephthalate is a linear saturated polyester resin.PET the main raw material of p-xylene and terephthalic acid (PTA) in PET with excellent properties (heat resistance, chemical resistance. Strong toughness, electrical insulation, safety etc.), cheap price, so widely used as fiber, film, engineering plastics, polyester bottles. HOPE -- not check, had never heard of, is recommended to check whether referred to the wrong PVC full name is Polyvinylchlorid, the main ingredients of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility, etc.. It is one of the world's favorite, is quite popular and is a widely used synthetic material. LDPE: low density polyethylene. Suitable for thin film, packaging film, cable insulation material, blow molded and foamed products. PP: polypropylene. Characteristics: non-toxic, tasteless, is small, the strength and the rigidity, hardness and heat resistance are superior to low pressure polyethylene, can be used at 100 degrees. It has good electrical insulation and high not affected by humidity, but the low temperature brittle, not wear-resisting, easy to aging. Suitable for making general machinery parts, corrosion resistant parts and insulating parts. Common acid, alkali and organic solvent it almost does not work, can be used for utensils. PS Polystyrene, Chinese name polystyrene is a thermoplastic synthetic resin, in the construction industry (insulation), packaging industry (damping plastic foam) is widely used, is one of the most widely used general-purpose plastics.
