Want to know what are the main properties of the epoxy glass fiber cloth laminate flat pad?

Epoxy glass fiber cloth laminate flat mat is made of epoxy phenolic layer glass cloth board for electrical engineering, which is made by physical processing. It has high mechanical and dielectric properties, heat resistance, and is suitable for the insulation of motors, transformers, ballasts and other slots with equal intervals. It is made of electrician special alkali-free glass fiber cloth impregnated with epoxy phenolic resin, baked and processed by hot pressing.

The laminate has high mechanical and dielectric properties, good heat resistance and moisture resistance, and has good machinability, and the heat resistance grade is B grade. It is suitable for insulating structural parts in motors and electrical appliances. It is a special insulating material for electric furnaces in steelmaking, aluminum plants, aluminum alloy plants, calcium carbide plants, etc.; and can be used in humid environments and transformers.

Let us take a look at the main performance of epoxy glass fiber cloth laminate flat pad:

1. Diverse forme. Diferite rășini, agenți de întărire și sisteme modificatoare se pot adapta aproape la cerințele diferitelor aplicații din formular, iar gama poate fi de la vâscozitate foarte scăzută până la solide cu punct de topire ridicat.

2. Vindecare convenabilă. Alegeți o varietate de agenți de întărire diferiți, sistemul de rășină epoxidică poate fi aproape vindecat în intervalul de temperatură de la 0 ~ 180 ℃.

3. Aderență puternică. Grupările hidroxil polare inerente și legăturile eterice din lanțul molecular al rășinilor epoxidice îl fac foarte adeziv la diferite substanțe. Contracția rășinii epoxidice este redusă la întărire, iar stresul intern generat este mic, ceea ce ajută și la îmbunătățirea rezistenței la aderență.

4. Low shrinkage. 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 during curing.

5. Proprietăți mecanice. Sistemul de rășini epoxidice întărite are proprietăți mecanice excelente.

Epoxy glass fiber cloth laminate flat mat is made of electrician alkali-free glass fiber cloth impregnated with epoxy resin, baked, hot pressed in a forming mold, and processed into a tube with a circular cross section, which is combined with an insulating pad.

According to customer requirements, the epoxy glass fiber cloth laminate flat mat can also be molded at one time by opening the mold, and the general material is SMC sheet molding. The product has high mechanical properties, dielectric properties and good machinability. It is suitable for insulating structural parts in electrical equipment, and can be used in damp environment and transformer oil.
