product description

Description of Diphenyl Ether Board

Diphenyl ether fiberglass cloth laminated board, short for diphenyl ether board, is made of alkali free fiberglass cloth for electrical purposes impregnated with diphenyl ether resin after baking and hot pressing with higher dielectric property and mechanical property, great machinability, excellent radiation resistance, corrosion resistance and self extinguishing. The insulation class is H class.

Application of Diphenyl Ether Board

Suitable for insulating structural spares in motors and electrical equipments.

Advantage of Diphenyl Ether Board

Diphenyl ether fiberglass cloth laminated board, produced by ZTelec Group using diphenyl ether resin or phenol modified diphenyl ether resin as raw materials, can be mass produced with full automatic production equipments. This product has the advantages of uniform appearance and color, small thickness tolerance and reliable quality. 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.
