product description
Description of Laminates for Insulation Gasket
Steel & Insulation sheet composites (SIC) material is made with combination of Glass Reinforced Epoxy (GRE) and steel core offering the strength and integrity of a mental which also maintains the Isolation characteristics of traditional GRE designs. This in turn ensures the highest levels of electrical isolation. This material provides excellent solution for resistance and withstand extremely corrosive condition such as CO2, H2S and generally used for high-pressure services. It is mainly used in the manufacturing of insulating gasket of sealing flange in piping connections from oil, gas, water, chemical and offshore industries.

Insulation Material
The laminate material is composed with Glass Reinforced Epoxy (NEMA G10,G11,Fr4,Fr5) for excellent insulation. It used as sealing materials in flanges to protects from leakage and penetration of fluids induced erosion with deformation.
