Durex Industries' custom silicone heaters take advantage of the unique properties of silicone rubber to provide flexible heating elements of unparalleled performance. Silicone rubber is calendared onto fiberglass cloth in a variety of thicknesses and constructions which serve as the basis for Durex's flexible silicone heaters. Generally, two layers of material containing an etched foil element or a precision wire wound element are vulcanized together to form a basic silicone heating element.
Although most silicone heaters are manufactured in a flat flexible heater shape, Durex regularly manufactures silicone rubber heaters in a variety of formed shapes. Forming can provide superior heat transfer, and ease of installation by the customer. A typical design would be a cylindrically shaped heating element that "snaps" onto a pipe of the same diameter. Using proprietary techniques, Durex can form silicone rubber heaters into more complex shapes depending on the customer's requirements.
