Steel & Insulation sheet composites (SIC) material is made with combination of Glass Reinforced Epoxy (GRE) and steel core.
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.
Structure of insulating Gasket Materials
Metal Core
Attached Stainless Metal Core between Glass Reinforced Epoxy performs superior sealing ability and reinforced insulation characteristic in high pressure. (Max ASME Class 2500) Standard core material is Stainless Steel 316L and other special material options are available depend on client requests.

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.
