Mylar is heated by two methyl ester and ethylene glycol in the related catalyst, after the ester exchange and vacuum condensation, biaxial stretching film. Mylar generally have white, black, transparent, color and other colors. Mylar has excellent tear strength, temperature resistance, weather resistance, moisture resistance, chemical resistance, and has a strong electrical insulation properties.

Mylar no shape, no odor, non-toxic, highly transparent;
Myla has excellent physical and mechanical properties, especially the impact resistance, tensile strength, bending strength, compressive strength, creep is small, size stability;
Myla has good heat resistance and low temperature resistance, in a wide temperature range with stable mechanical properties, dimensional stability, conductive properties and flame retardant, can be used in -60~120;
Myla low water absorption, small shrinkage, high dimensional accuracy, good size stability, film permeability is small, is a self extinguishing material, light stability, but not resistant to UV light, good weather resistance, oil resistance, acid resistance.
Mylar performance: widely used in various electronic, electrical insulation, shielding, protection, cosmetics, food, toys, printing, etc..
Mylar uses: widely used in electronics, electrical, electrical, motor, motor, electrical, digital products.
