epoxy board

What is an epoxy board?

Electrical Insulating material-Epoxy board, also known as 3240 epoxy phenolic fiberglass cloth laminate, the color is yellow, black, is made of electrician special alkali-free glass fiber cloth dipped in epoxy phenolic resin, baked and hot pressed. Our company mainly produces epoxy board sizes:  1020*2020 mm, 1220*2020mm, 1220*2470mm, 1220*1220mm and 1020*1020 mm.

Features of epoxy insulation board:

Epoxy board has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good machinability.

1. Higher combat strength. Epoxy sheets have various substances with high adhesion. The shrinkage of the epoxy resin during the curing process is low, and the internal stress generated is small, which also contributes to the improvement of the adhesion strength.
2, excellent mechanical properties. The epoxy system can be cured in a temperature range of 0 to 180 °C. Mechanical behavior. The cured epoxy resin system has excellent mechanical properties.
4. Lower shrinkage. The reaction between the epoxy resin and the curing agent used is an addition reaction by direct ring-opening polymerization or an epoxy group-containing resin molecule with or without water or other volatile by-products. Compared with unsaturated polyester resin, phenolic resin, it shows very low shrinkage during curing.

Application of epoxy board:

The epoxy resin sheet has a heat resistance class of B. It is suitable for use as insulation structural parts in motors and electrical equipment, and can be used in humid environments and transformer oils.

Epoxy resin sheet is one of our company’s main products. please contact us if you need it .Looking forward to working with you. Email is jiangqian@ztaero.com .
