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.

Silicone Foam Die Cut

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.
