The difference between G11 epoxy fiberglass board and G10 epoxy fiberglass board
Epoxy glass fiber board also has many materials. It is a finished product made by heating and pressing with glass fiber cloth and epoxy resin. Most of the time, the epoxy glass fiber board is yellow 3240 epoxy glass fiber board, G10 epoxy Composition performance of fiberglass board and G11 epoxy fiberglass board.
The composition of G10 epoxy glass fiber board: It is made of imported electronic grade alkali-free glass fiber cloth impregnated with imported epoxy resin, and corresponding imported flame retardant, adhesive and other additives are added; it is processed by precision hot pressing.
The performance of G10 epoxy glass fiber board: flame retardant grade UL94-VO, good mechanical properties at high temperature, good processing performance and insulation performance.
Application: Used as insulating structural parts in motors and electrical equipment, such as circuit breakers, switch cabinets, transformers, DC motors, AC contactors, explosion-proof electrical appliances and other electrical appliances.
After understanding G10 epoxy glass fiber board, let’s look at the related performance description of G11 epoxy glass fiber board:
Application characteristics of G11 epoxy glass fiber board:
One: 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 very low viscosity to high melting point solids;
Second: Convenient curing. Choose a variety of different curing agents, the epoxy resin system can almost be cured in the temperature range of 0 ~ 180 ℃;
Third: 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;
Fourth: 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.
G11 epoxy glass fiber board composition: imported electrician’s alkali-free glass fiber cloth is impregnated with imported epoxy resin, and the corresponding imported flame retardant, adhesive and other additives are added; the cardboard-like insulating material is processed by hot pressing.
The performance of G11 epoxy glass fiber board: the same as G10 epoxy glass fiber board.
Application: Insulating structural parts in motors and electrical equipment, which can be used in humid environments and transformer oil, high-voltage switch cabinets, high-voltage switches, etc.
The two materials have different composition and production processes, so the performance is also different.
