Epoxy plate and epoxy glass fiber board, epoxy phenolic glass cloth laminated sheet, epoxy resin is a polymer compound, a molecule containing two or more than two epoxy groups, in addition to individual, their relative molecular mass is not high. The molecular structure of epoxy resin in the molecular chain with lively epoxy group as its characteristic, the epoxy groups can be located in the end of the chain, or intermediate molecules into ring like structures. Because the molecular structure of epoxy containing active, so that they can be cured with various types of agent crosslinking reaction and the formation of insoluble and infusible polymers with three direction mesh structure.
Epoxy board: fiberglass cloth is made of epoxy resin and heated and pressed. It has high mechanical performance at moderate temperature and stable electrical performance under high humidity. It is suitable for mechanical, electrical and electronic parts with high insulation structure. It has high mechanical and dielectric properties, good heat resistance and moisture resistance. Heat resistant class F (155 degree).
Specification thickness: 0.5 ~ 100mm
Color: yellow, water green, black
In the case of high temperature 180 degrees, heating deformation is generally not heated with other metals in one piece, which may cause sheet metal deformation
1, diverse forms. All kinds of resin, curing agent, modifier system almost can adapt to all kinds of application form of the request, which can range from extremely low viscosity to high melting point of solid.
2, easy curing. The epoxy resin system can be cured almost in the temperature range of 0~180 degrees with various curing agents.
3, strong adhesion. The existence of polar hydroxyl groups and ether bonds in the molecular chain of epoxy resin makes it highly adhesive to various materials. When epoxy resin is cured, the shrinkage is low and the internal stress is small, which also helps to improve the adhesion strength.
4, low contractility. 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.
5, mechanical properties. The cured epoxy resin system has excellent mechanical properties.
