Platinum Cured Silicone Foam Availability
- August 19, 2021
Stockwell Elastomerics is known for its readily available inventory of high performance silicone foam. While supply chain challenges persist for the near term, Stockwell Elastomerics is positioned to support its customers in the silicone foam market.
Rogers Corporation and Saint-Gobain manufacture high performance, platinum cured silicone foam. Although their products have some minor differences, all of them provide the unique benefits of silicone foam. Rogers’ BISCO® and Saint-Gobain’s NORSEAL® silicone foam product families are described in more detail on the silicone foam materials page.
Silicone foams are offered in different firmness values, cell structures, and densities. These details may be important to create a robust seal for each specific application. Technical data sheets with more specific are available on the silicone foam datasheets page. BISCO HT-800 and NORSEAL F-20 are great where water sealing is required (typically IP66 range). NORSEAL F-12, BISCO BF-1000, BISCO HT-870 are considered open cell structure. They can handle splashing but are better for applications that don’t require rigorous water sealing. These include thermal management, dust, splashing, etc.
The chart below compares many of the soft to medium firmness silicone foams.
