G11 epoxy insulation board
G11 epoxy insulation board
G11 epoxy insulating board is made of imported electrician's alkali-free glass fiber cloth impregnated with imported epoxy resin, and added with corresponding imported flame retardant, adhesive and other additives; it is a cardboard-like insulating material processed by hot pressing. Flame retardant grade UL94-VO grade, good mechanical properties at high temperatures, good processing performance and insulation performance, is a commonly used raw material for insulating structural parts in motors and electrical equipment, G11 epoxy insulation board can also be used in humid environments and transformers Use a high-voltage switchgear, a high-voltage switch, etc. in the oil.
Application characteristics of G11 epoxy board:
1. Various forms. Various resins, curing agents, and modifier systems can almost adapt to the requirements of various applications on the form, which can range from extremely low viscosity to high melting point solids
2. Convenient curing. Choose a variety of different curing agents, the epoxy resin system can almost be cured in the temperature range of 0 ~ 180 ℃;
3.strong adhesion. The inherent polar hydroxyl groups and ether bonds in the molecular chain of epoxy resins make it highly adhesive to various substances. The shrinkage of epoxy resin is low when curing, and the internal stress generated is small, which also helps to improve the adhesion strength
4. low contractility. The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage (less than 2%) during the curing process; fifth: mechanical properties. The cured epoxy resin system has excellent mechanical properties.
