pet bottle raw material suppliers
PET (Polyethylene Terephthalate) Resin is cream or pale-yellow crystal, with smooth and shiny surface. Resistance to creep deformation, fatigue resistance, abrasion resistance and dimensional stability are perfect. Small wear and tear but high hardness, its toughness is the largest in thermoplastic. The electrical insulation of PET is perfect and little be affected by temperature, however, poor corona resistance. PET is non-toxic, weather resistance, and anti-chemical stability is very good. PET is low water absorption, resistance to weak acids and organic solvents. Intolerance of hot water immersion and alkali. In addition to the excellent properties inherent in conventional polyester fiber (such as high strength, good elasticity, good heat and wear resistance, etc.), it also has the characteristics of soft luster, good dyeing and good drape.
Feature:
1.Oil resistant, fat resistant, acid resistant, alkali resistant, resistant to most solvents.
2.Excellent resistance performance of high and low temperature.
3.Non-toxic, tasteless, health and safety.
4.Transparent, UV blocking, good glossiness.
