Production Description
3240 epoxy fiberglass sheet is made of alkali-free glass fiber cloth impregnated with epoxy phenolic resin, baked and hot pressed. It has high mechanical, dielectric properties, good heat resistance and moisture resistance. 3240 epoxy fiberglass sheet has high mechanical strength at medium temperature, and good electrical performance stability under high humidity. The surface of the board is required to be smooth, free of bubbles, no pits and wrinkles.
As the price of 3240-B is cheaper than 3240-A and has good practicability, it is more common in the market. For more information, please kindly contact our sellers.
Application
3240 epoxy fiberglass sheet is used in machinery, electric appliance and electronic high insulation components, also, it is suitable for motors and electrical equipment as an insulation parts and can be used in humid environments and transformer oil.
The Main Application of 3240 Epoxy Fiberglass Sheet:
● Chemical machinery parts, General machinery parts
● Gear, Generators, Pads, Bases, Baffles, Transformer, Fixture Invertor, Motor, Electric Insulation Component
● Fixture Board, the Mold Plate, High and Low Voltages Distribution Box
● PCB, ICT Fixture, Molding Machine, Drilling Machine, Mesa Grinding Pads
