With their medium watt density (15 or 30 watts per feet) and industrial style heating of 120 to 240 watts, these silicone rubber extruded were built for industrial uses. Their rubber outer cover provides abrasion and dielectric protection, making them ideal for applications when moisture, chemical, and abrasion resistance is required. Able to withstand temperatures of 450°F/ 232°C, they are ideal for when you need something that goes beyond the capabilities of elastomer insulated cables and tapes.
