BI MATERIAL GASKETS
Product catalog summary
Material and Manufacturing:
Bi-material gaskets are composed of silicone or fluorosilicone combined with a second silicone material infused with conductive particles such as aluminum, copper, nickel, or graphite. These materials are processed through extrusion, molding, and splicing, and are packaged in sealed bags. An anti-stretch option is available.

Description:
The gaskets are designed with a conductive silicone layer that partially covers the gasket section, providing resistance and flexibility. They are effective for IP sealing and shielding, particularly in harsh environments with exposure to salt spray, electrolytic agents, oil, and solvents.

Catalog excerpts
Description: Bi material gaskets are made of silicone or fluorosilicone, with a second silicone material charged with conductive particles. These two materials are extruded simultaneously. The conductive silicone partially covers the gasket section. This process makes the bi material gasket resistant and flexible. Several gasket profiles are available. This type of gasket is used very efficiently for IP sealing and shielding over time. Our range of bi material gaskets is developed to withstand the corrosion and aging problems encountered in aggressive environments: salt spray, electrolytic agents, oil, and solvents. AVAILABILITY : Bi-material gasket ■ Hook option for holding in the groove
