1- Adopt epoxy resin APG technology to manufacture, has good appearance, excellent mechanical and electrical performance.

2- Adopt high tenacity epoxy resin to manufacture, has excellent mechanical performance. Also adopt low reaction acitve system, has low material solidation speed and interior forces, can improve the mechanical performance of the products in maximum.

3- Add active silica micro powder, can further improve the mechanical performance of epoxy resin, also assure of good electrical insulation performance under long-term moisture enviroment.

4- Add organic pigment, the products have nice surface with high insulation performance.
