At NEDC, it is all about materials. When talking about die cutting, or waterjet cutting and what NEDC can do, material is often the first topic of discussion. One of the more versatile materials that NEDC deals with, is silicone foam. To be clear, silicone foam is different than silicone sponge. Silicone foam gaskets come in a number of thicknesses, colors, and firmnesses. All the silicone foams below have in common that they are silicone foam that are UL94 V0 flame retardant, and are lightweight solutions. These foams have the common fixings of silicone, high volume resistivity for insulation, great resistance to ozone, and ultraviolet light.
NORSEAL® F12 Silicone Foam, Soft Cellular Silicone Foam. This foam is great for shock absorption and gasketing. It oftentimes serves as a cushion in applications. The compression deflection(psi) @ 25% is 3. It comes in multiple colors, gray(standard), white, black, or brown. It has a fabric finish that is a textured feel on one side of the foam. The thicknesses of this foam range from .062’’’ to 1’’ in thickness.
Rogers Corp. BISCO® HT-800, Medium Cellular Silicone Foam. NEDC uses this foam in applications requiring less compression but need a good solution for gasketing. The compression deflection(psi) @ 25% is 9. This foam comes in a variety of colors, gray(standard), black, and red. BISCO® HT-800 can be provided in thicknesses ranging from .032” to .500” thick.
Rogers Corp. BISCO® HT-870, Soft Cellular Silicone Foam. This silicone foams applications vary – ranging from HVAC units to electronic cabinets. The compression deflection(psi) @ 25% is 4, allowing low compression but great sealing. This material can be supplied in black(standard), and red. BISCO® HT-870 can be supplied in thicknesses ranging from .062” to .500” thick.
Rogers Corp. BISCO® HT-820, Firm Cellular Silicone Foam, This silicone foams applications vary from lighting fixtures to HVAC units, and other applications. The compression deflection(psi) @ 25% is 16. This elastomer comes in the color gray. BISCO® HT-820 can be provided in thicknesses ranging from .032” to .250” thick.
Rogers Corp. BISCO® HT-840, Extra Firm Cellular Silicone Foam, This silicone foam is great in applications that have a lot of force in order to force the gasket to provide a seal. The extra firmness can be a challenge in some applications. The compression deflection(psi) @ 25% is 22. The color availability is gray on this specific foam. Thicknesses range from .062’’ to .250’’ thick for BISCO® HT-840.
