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. Rôzne formy. Rôzne živice, vytvrdzovacie činidlá a modifikačné systémy sa môžu takmer prispôsobiť požiadavkám rôznych aplikácií na formu a rozsah môže byť od veľmi nízkej viskozity po tuhé látky s vysokou teplotou topenia.

2. Pohodlné vytvrdzovanie. Vyberte si množstvo rôznych tvrdidiel, systém epoxidovej živice je možné takmer vytvrdiť v teplotnom rozsahu 0 až 180 ° C.

3. Silná priľnavosť. Vďaka inherentným polárnym hydroxylovým skupinám a éterovým väzbám v molekulárnom reťazci epoxidových živíc je vysoko priľnavý k rôznym látkam. Zrážanie epoxidovej živice je pri vytvrdzovaní nízke a generované vnútorné napätie je malé, čo tiež pomáha zlepšiť pevnosť adhézie.

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. Mechanické vlastnosti. Vytvrdený systém epoxidovej živice má vynikajúce mechanické vlastnosti.

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.
