BISCO® Cellular Silicone Materials


Many engineers prefer to use gasketing materials like BISCO Silicones and PORON Urethanes that are already certified for use under several standards including UL-508 (industrial control equipment), UL-1570-2 (HID lighting fixtures), and especially UL-50E (electrical enclosures) with testing done to the new periodic recompression standard. These certifications enable designers to design-in gasket material without testing the material itself, effectively simplifying the screening process.
