3240 Insulating Glass Epoxy Laminate

Short Description:

Epoxy board of this product: glass fiber cloth is bonded with epoxy resin and made by heating and pressing. The model is 3240. It has high mechanical properties at medium temperature and stable electrical properties at high temperature. It is suitable for high-insulation structural parts for machinery, electrical appliances and electronics, with high mechanical and dielectric properties, good heat resistance and moisture resistance. Heat resistance class E (125 degrees).

Regular thickness: 0.5～100mm
Regular size: 1020×2040mm
It is heated and deformed at a high temperature of 180℃, generally not heated with other metals, which may cause deformation of the metal sheet
