Five Properties Of Film

Shenzhen Jgoal Prototype Co.,Ltd | Updated: Jan 13, 2017

Five properties of PET film

(1) General milky white translucent or colorless transparent PET film, a relative density of 1.38, light transmission rate of 90%,PET belong to the secondary barrier materials, permeability to O2 for 50~90cm3 • mm/(M2 · d · MPa), CO2 permeability coefficients for 180cm3 • mm/(M2 · d · MPa), PET water absorption rate of 0.6%, large absorbent.

(2) high mechanical properties tensile strength of PET film, is comparable to aluminium foil, is HDPE film 9 times, 3 times is the PC and PA film, enhanced PET creep small, excellent fatigue resistance (better than enhance the PC and PA), good resistance to wear and friction resistance. The mechanical properties of PET less affected by temperature.

(3) the thermal properties of heat-resistant properties of pure PET films are not high, but after enhancement increased 180 ℃ better mechanical properties than PF laminates are better reinforced thermoplastic plastics heat-resistant varieties, PET good heat aging, embrittlement temperature of-70 degrees centigrade, at-30 c still has a certain toughness. PET nonflammable, yellow flame, drips.

(4) Although the electrical properties of PET for Polar polymer, but excellent electrical insulation, at high frequencies are still well kept, PET less Corona-resistant and cannot be used for high-voltage insulation; electric insulation under the influence of temperature and humidity, and with great influence on the climate.

(5) environmental performance of PET film containing ester bonds, in conditions of high temperature and steam non water, acids, and alkalis, PET of organic solvents, such as acetone, benzene, toluene, chloroform, carbon tetrachloride and oil stability, number of oxidants such as hydrogen peroxide, sodium hypochlorite and potassium dichromate, also has a high resistance.
