Silicone Elastomers for Automotive

Automotive Elastomers

Our products are used in a wide variety of automotive applications. Momentive’s silicone products are easy to process and generally maintain their elastomeric properties in extreme hot and cold environments, offer excellent dielectric properties, resist weathering and offer low compression set. Momentive’s silicone elastomers are excellent candidates to consider for a variety of sealing, bonding and insulating applications. Momentive also offers specialty products that can provide excellent resistance to many types of automotive fluids. Typical applications include: Gaskets, O-rings, Hoses, Spark plug boots, Diaphragms, Connector seals, Exhaust hangers, Fuel system valves, Powertrain applications, Oil-system seals. We offer a portfolio of liquid silicone rubber (LSR) and high consistency rubber (HCR) products. We can also deliver ready-to-use, custom elastomers based on individual customer needs.
