Processing of Plastic materials , it's depending upon raw material MFI , Processing Temperature, Glass Transition Temperature, Density of materials, Mw etc . Mostly SOLAR Encapsulant grade EVA process at 90 to 110 degree centigrade. POE also process at 80 to 115 degree centigrade for Solar Encapsulant grade. In Solar Encapsulant formulation : We use raw material Elvax150 Peroxide Silane UV Absorbers Antioxidant UV residents Additives for Increase volume resistivity. Machinery : Mitsubishi, GWell , Breyer & Mitsubishi, & some Italian machinery is the best quality machinery for output , low gauge band , High volume resistivity, best electrical insulation resistant property.
