Epoxy resin heating plate is also called epoxy glass fiber heating plate, and epoxy phenolic laminated glass cloth heating plate.
1.Product introduction of Epoxy resin heating sheet
Epoxy resin heating plate is also called epoxy glass fiber heating plate, and epoxy phenolic laminated glass cloth heating plate. Epoxy plate: The cloth is bonded with epoxy resin and made by heating and pressurizing. It has high mechanical properties at medium temperature and stable electrical properties at high humidity. Suitable for mechanical, electrical and electronic parts with high insulation structure, with high mechanical and dielectric properties, good heat resistance and moisture resistance. Heat-resistant grade F (155 degrees) is deformed by heat at high temperature of 180℃, with specification thickness of 0.5～100mm.
2. Main features of Epoxy resin heating sheet
(1). Various forms. Various resin, curing agent and modifier systems can almost meet the requirements of various applications, ranging from extremely low viscosity to high melting point solids.
(2). Convenient curing. With different curing agents, the epoxy resin system can be cured almost in the temperature range of 0 ~ 180℃.
(3). Strong adhesion. The existence of polar hydroxyl and ether bonds in the molecular chain of epoxy resin makes it have high adhesion to various substances. The shrinkage of epoxy resin during curing is low and the internal stress is small, which is also helpful to improve the adhesion strength.
(4). Low contractibility. The reaction between epoxy resin and curing agent is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in resin molecules, and no water or other volatile by-products are released. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.
(5). Mechanical properties. The cured epoxy resin system has excellent mechanical properties.ng service life and not easy to age.
3. The main application of Epoxy resin heating sheet
