Silicone foam rubber, (currently the subject of an ongoing materials shortage), is one of the higher performing foam materials we die cut at JBC. Used in gaskets, seals, heat shields, fire stops, and more, it has a very strong (low) compression set and extremely effective resistance to heat, cosmic radiation, weathering, and other environmental factors. As a result, silicone gaskets and seals typically see a longer shelf life and better product durability than less costly alternatives.
Yet, for those tasked with selecting the “right” material for a gasket that will need to withstand high heat and temperature extremes, it is not quite as simple as saying, “use silicone.”
There are many variations of silicone foam, not only in composition (open cell vs. closed cell), but in color, weight, thickness, density, presentation, and chemistry. And, as a product design engineer, those are only a few of the choices you have to make when choosing the right material for your application.
Rather than dive into the specific details of the myriad of options available, today’s post uses real-life stories to demonstrate the benefits of silicone -- or, more specifically, the benefits of one of the more popular families of silicone rubber products: BISCO ® Silicone,
