product description
Description of 3240 Epoxy Sheet
3240 epoxy sheet is made of non alkali fiberglass cloth for electrical purposes impregnated with epoxy resin and phenolic resin under heat and hot pressing with excellent dielectric property and mechanical property, good heat and moisture resistance, strong mechanical processing property. It has high mechanical strength at medium temperature and stable dielectric performance at high humidity. The insulation class is B class.
Application of 3240 Epoxy Sheet
Suitable for electrical, electronic, motor and mechanical industries and other industries. It can be processed into various insulation accessories and insulation structural parts of equipments, and can be used in humid environment and transformer oil.
Thickness: 0.5~50mm under normal, and thick board with 50~150mm is available as required.
Advantage of 3240 Epoxy Sheet
3240 epoxy sheet, produced by ZTelec Group using non alkali fiberglass cloth for electrical purposes, epoxy resin and phenolic resin as raw materials, can be mass-produced with advanced production equipment and automatic production line. This product has the advantages of reliable quality, smooth surface, neat cutting edge, uniform color and small thickness tolerance with strict manufacturing technology. The mechanical and electrical properties of products are superior to the similar one of other companies. Its quality is recognized by domestic and foreign large enterprises such as Lens Technology in China and Schneider Electric and sold overseas such as European and American areas.
