More Information
GMW16392
- GMW16392 is an automotive specification from General Motors.
- This specification covers silicone foam materials used for sealing various components within vehicles. These silicone foam materials are recommended for applications where the operating temperature range is -55 °C to +200 °C. Materials can be produced in continuous rolls, sheets, or cast bun blocks.
- Our material is approved and listed for GMW16392 Class 2 Type 2 on the international General Motors MATSPC database.
- Material Class II: Closed Cell Foam.
- Material Definition: Type 2 – This is a medium modulus (medium cellular) foam, which can be easily compressed and used as noise isolation and as an air, dust, and fluid seal.
Rechargeable Energy Storage Systems
- This silicone foam meets the rechargeable energy storage systems (RESS) requirements for compression set and water impermeability, making it safe to use in electric and hybrid electric vehicles. Best suited for use in fluid and dust seals, vibration isolation and battery cell alignment.
