Product description

Parameters

　　The basic components of drawing products are resin and glass fiber (including cloth, felt, etc.), which use glass fiber (including cloth, felt, etc.) as the reinforcing material, and resin (epoxy resin or polyester resin, etc.) as the glue joint The agent is cured and compounded at high temperature in the drawing mold. It has a series of excellent characteristics such as high temperature resistance, corrosion resistance, high strength, small specific gravity, low moisture absorption, small extension and good insulation.
