While a majority of today’s leading automakers and their suppliers may have facilities in the U.S., many still buy and source raw materials and parts from all over the world. Gaskets, seals, fasteners, and the raw materials they are die cut from are no exception. Yet when manufacturing stateside, sourcing materials and die cut components from overseas vendors can present challenges—particularly when it comes to meeting tight production timelines, managing costs, and accurately forecasting inventory levels.

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,
Check out the following stories, all of which were published on the Rogers Corporation website:
Double-sided foam tapes are used for temporary or permanent fastening, packaging, acoustic dampening, thermal insulation, and gap filling. They are made of open cell or closed cell foams, coated with different types of pressure-sensitive adhesives (PSAs), and come in a variety of thicknesses. If needed, they can also be die cut, tabbed and/or delivered kiss-cut on rolls for ease of use.
The performance properties of double-sided foam tapes include shock absorption, vibration dampening, compensation for uneven surfaces, and thermal sealing between substrates with different temperatures. These tapes can also be used as seals to prevent the passage of air, gases, moisture, and humidity.
Here are some of the advantages of using double-sided foam tapes.

Medical die cutting for FDA USP VI silicones produces components for medical devices and equipment that are safe for direct or indirect physical contact with patients. Examples include seals, gaskets, washers, wearables, and diagnostics. FDA USP Class VI silicones aren’t suitable for medical implants, but these specialty elastomers still meet stringent standards for cleanliness and purity.
FDA USP VI silicones for medical devices meet strict standards for cleanliness and purity. The U.S. Food and Drug Administration (FDA) defines its requirements in section CFR 177.2600 of the U.S. Code of Federal Regulations (CFR). The United State Pharmacopeia (USP), a non-profit scientific organization, subjects USP Class VI materials to Biological Reactivity Tests, In Vivo that are directly related to end-use.
Medical silicones that pass these toxicity tests are safe for direct and indirect patient contact. As a medical die cutter, JBC Technologies sources FDA USP VI silicones from a trusted supplier that’s received a Certificate of Compliance (COC) from a leading medical research organization. Unlike some other medical elastomers, these silicones are wholly FDA USP VI compliant – and not just at the ingredient level.
In this article from JBC Technologies, you’ll learn how the way that medical silicones are made determines their cleanliness, purity, and quality. You’ll also learn about the different thicknesses and durometers of the FDA USP VI silicones that JBC can source, convert, and die cut for you.
