Silica fiberglass filtration for foundry


    Silica fiberglass filtration for foundry is made from silica fiberglass scrim or mock leno scrim that coated on surface with high temperature resistant coating. It used as filtration for molten metal, can improve quality of coasting. Silica fiberglass filtration has good properties of high temperature resistant, scour resistance, low gas evolution, easy to use and economic. It’s suitable for grey cast iron, nodular cast iron and small size cast steel casting filtration.
    Sheet size: standard size300×150mm, max. Size: 1000×900mm. Non-standard size is available by order.
