3240 epoxy laminate plate surface smooth, no bubbles, no pits and wrinkles, but allow does not affect other defects, such as: using scratch, indentation, stain and a few spots. The edge should be cut neatly, and the end face shall not be divided into layers and cracks.
Temperature tolerance grade:B
Color:Natural color (yellow), green, etc.
Characteristic：After curing epoxy resin system has excellent mechanical properties, high temperature strength Jie machine, good electrical properties under high humidity.
Electrical property:The cured epoxy resin system is an excellent insulating material with high dielectric properties, resistance to surface leakage and arc resistance
Uses:It is suitable for mechanical, electrical, electronic, electrical and other fields. Also used in the processing of insulation parts, processing into all kinds of insulation parts and equipment insulation structure parts.
Thickness:Under normal circumstances, 0.3 ~ 50mm, also can be produced according to the requirements of 50~150mm thick plate.
The epoxy resin and the curing agent reacts by direct addition reaction or resin molecules of the epoxy group ring opening polymerization, no water or other volatile by-products release. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.
