Product Description

PET performance editing

(1) general performance PET resin is milky white translucent or colorless transparent body with a relative density of 1.38 and a transmittance of 90%.PET is a medium barrier material, with a permeability coefficient of 50 ~ 90cm3·mm/(m2·d·MPa) to O2 and 180cm3·mm/(m2·d·MPa) to CO2.The water absorption rate of PET was 0.6%, and its water absorption was large.

(2) mechanical properties PET film has high tensile strength, which is comparable to aluminum foil, 9 times of HDPE film and 3 times of PC and PA film.Enhanced PET has low creep, excellent fatigue resistance (better than PC and PA), good wear resistance and good friction resistance.The mechanical properties of PET are less affected by temperature.

(3) the thermal performance of pure PET plastic heat resistant performance is not high, but increased significantly after enhancement processing, mechanical properties at 180 ºC than PF laminate is good, is to enhance the good varieties of thermoplastic engineering plastics in the heat.PET heat ageing and brittle temperature to - 70 ºC, still has a certain toughness when - 30 ºC.PET is not easy to burn, the flame is yellow, dripping.

(4) although PET is a polar polymer, it has good electrical insulation and can be maintained well at high frequencies.PET has poor corona resistance and cannot be used for high voltage insulation.Electrical insulation is affected by temperature and humidity, and is affected by humidity.

(5) environmental performance PET contains ester bonds and is not resistant to water, acid and alkali at high temperature and water vapor.PET in organic solvents such as acetone, benzene, toluene, trichloroethane, carbon tetrachloride and stable oil, on some oxidant such as hydrogen peroxide, sodium hypochlorite and potassium dichromate has higher resistance.PET has good weather resistance and can be used outdoors for a long time.
