Moulding material (Press material) DSV-2O BH4300-5
Product Introduction
This series of products are thermosetting molding plastics made of e-glass fiber and modified phenolic resin by soaking and baking. It is used for pressing heat-resistant, moisture-proof, mildew proof, high mechanical strength, good flame retardant insulating parts, but also according to the requirements of the parts, the fiber can be properly combined and arranged, with high tensile strength and bending strength, and suitable for wet conditions.
