Silicone Gasketing​

  • 12″ × 12″ silicone gasketing for fuel cell fixtures
  • Soft 35A durometer for superior conformability
  • Flexible across –80°F to +425°F temperature range
  • Protective peel-off masking keeps the sheet clean
  • Thin-gauge options: 0.010″ and 0.020″ with tight tolerances

Product Description 

This 12″ × 12″ Silicone Gasketing Sheet is engineered for precision sealing in fuel cell fixtures and high-demand thermal environments. Made from solid HT6135 silicone elastomer, it offers exceptional softness and conformability, outperforming standard silicone materials when used in sensitive assemblies.
The gasketing remains flexible across a broad temperature range, while a peel-off protective layer keeps the sheet clean during storage and installation.
Ideal for applications involving HT-PEMFC, PAFC, and other high-temperature electrochemical systems, this material ensures stable, reliable performance under demanding conditions.
