Properties of PET RESIN:
PET 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.
