product description
Description of Semiconductor Plate
3241 semiconductor laminated glass cloth board is a plateshape laminated product that made of electrical alkali-free glass cloth impregnated with epoxy phenolic anti-halo resin glue by baking and hot pressing. The product has semi-conductive properties, which is suitable for anti-halo materials in large motor slots and can be used as a material for wear-resistant structural parts at high temperatures.
