Elastomers for Automotive and E-Mobility

Silicone Elastomers for Automotive Applications and Electromobility (E-Mobility)

Our silicone elastomers are used in a wide variety of automotive applications. Momentive’s silicone products are easy to process and maintain their elastomeric properties in extreme hot and cold environments, offering excellent dielectric properties, resisting weathering, and offering low compression. 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
  • Ignition cables
  • Air-management system gaskets
  • Exhaust hangers
  • Fuel system valves
  • Powertrain applications
  • Oil-system seals

NEVSil™: Specialty Elastomers for New Energy Vehicles

Silicone’s unique properties enable Momentive’s materials to excel in a wide breadth of new energy vehicles' applications. Momentive’s LSR- and HCR- based material technologies are engineering enablers, providing the ability to meet and exceed demanding application performance requirements of new energy vehicles, today as well as tomorrow. Some of the key material characteristics inherent to addressing such challenges and solving these complex requirements are:

  • High thermal stability and temperature resistance
  • Low compression set
  • Equivalent to UL94 V0 flame-retardant performance (1mm thickness)
  • Self-lubricating properties
  • Low viscosity
  • Fast cure
  • Low modulus
  • Increased crack resistance
  • Outstanding resistance to aging
  • Easy to color
  • Self-bonding
  • Thermal conductivity
 

Typical applications include:

  • UL94 V-0 specified flame retardant parts/applications
  • High voltage connectors
  • Heat resistant molded components: seals, gaskets, O-rings, etc.
  • Boots
  • Heat transfer pads and gaskets
  • Under hood cooling parts
  • Battery sealing applications
