EPGC Sheet

The product is made of alkali-free glass cloth impregnated by epoxy resin by processing under heat and pressure. It has high dielectric and good mechanical properties.

EPGC201 sheet: High mechanical applications in middle grade temperature, stable electrical applications in high humidity conditions, suitable for as insulation structural parts of Class F machinery and electric equipment.

EPGC202 sheet:Similar to EPGC201, with flame resistance, good electrical applications in high humidity conditions, suitable as insulation structural parts for Class F machinery and electric equipment that require flame resistance

EPGC203 sheet:Similar to EPGC201, with high mechanical applications, chemical resistance, and permanent insulation strength in high temperature, Suitable as insulation structure for Class F machinery, electrical equipment and chemical corrosive environment application.

EPGC204 sheet:Similar to EPGC201 sheet, with flame resistance, suitable as insulation structural parts for class F machinery and electric equipment that require flame resistance.

EPGC308 sheet:Similar to EPGC201 sheet, with high mechanical applications, Suitable as insulation structure for class F machinery, electrical equipment.
