The epoxy insulating washer is made of 3240 / G10 /G11 epoxy board. It has high mechanical performance at medium temperature and stable electrical performance at high temperature. It is suitable for high-insulation structural parts for machinery, electrical appliances and electronics. It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and heat resistance class F. The washer is made of epoxy resin insulating fiber laminate as the base material and processed by lathes, grinders and punches.

Heat resistance and moisture resistance of epoxy insulating washer:

1. This product has high mechanical and dielectric properties, good heat resistance and moisture resistance, and has good machinability, and the heat resistance grade is B grade.

2. This product is suitable for use as insulating structural parts in motors and electrical equipment, and can be used in humid environments and transformer oil.

3. With high mechanical and electrical properties, it is widely used as insulating materials and components in generators, motors, and electronic appliances. It is also very suitable in transformer oil environment and humidity environment.

4. The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or the 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.

The epoxy insulating washer have a small contact area with conventional iron gaskets, especially where the pressure near the bolts is usually very large. With the increase of the distance from the bolts, the pressure drops rapidly. The washer made of epoxy pouring can be in full contact with the bottom surface and the base surface of the main machine base, so as to ensure the accurate positioning and centering of the main machine and the shaft system. And the product has a lower modulus of elasticity. When the ship is sailing at sea, the local transient pressure is induced by vibration, which can be alleviated and evenly distributed on the supporting surface, so that the bolts and washers will not be damaged or deformed due to the local transient pressure accident.
