The performance of the PET

General properties of PET resin is milky translucent or colorless transparent body,the relative density of 1.38,a light transmittance of 90%.PET barrier material belonged to the middle of the O2 permeability coefficient of 50 ~ 90cm3•mm/(m2•d•MPa),for CO2 permeation coefficient of 180cm3•mm/(m2•d•MPa).PET water absorption of 0.6%,a large water absorption.

High tensile strength of the mechanical properties of PET film,comparable with aluminum foil,is nine times the HDPE film is three times the PC and PA membranes.PET enhanced creep resistance is small,an excellent fatigue resistance (better than reinforced PC and PA),a good wear resistance and abrasion resistance.Mechanical properties of PET are less temperature.

Heat resistance thermal properties of pure PET plastic is not high,but the enhancement significantly improve the mechanical properties at 180 ℃ is better than PF when the laminate is heat-resistant reinforced thermoplastic engineering plastics better varieties.PET heat aging resistance,brittle temperature of -70 ℃,while at -30 ℃ still has certain toughness.PET nonflammable,yellow flame,there dripping.
Although the polarity of the electrical properties of PET polymer excellent in electrical insulating property,but,at high frequencies still well maintained.PET's corona resistance is poor,not for high voltage insulation;electrical insulation affected by temperature and humidity,and greater humidity.

PET environmental properties containing an ester bond,and not water vapor at high temperature conditions,an acid and a base.PET organic solvent such as acetone,benzene,toluene,trichloroethane,carbon tetrachloride and the stability of oil,some of the oxidant such as hydrogen peroxide,sodium hypochlorite and potassium dichromate,also have a higher resistance.PET excellent weatherability,long-term for the outdoors.

Xiamen XieXin Plastic Products Co., Ltd,is a professional pet clear boxes manufacturer.It is founded in 2006,but the founder and the core management team have more than 10years plastic box industry work experience,accumulate rich experience in such field.
