Silicone Rubber Properties of Silicone Rubber Heating Blankets

pre-formed-stack-2Silicone rubber is ideally suited for the production of heater mats with its low thermal mass and superb electrical insulation properties, it allows high power densities with fast response to temperature control. With silicones wide temperature range tolerance of – 60°C to 230°C, being thin and lightweight it has a distinct advantage over other forms of heating elements. Where direct precise and intimate heating is required, a silicone heating blanket is the ideal solution.

Using evenly spaced resistance wires laminated between sheets of silicone, wire wound silicone heating blankets are ideal for prototyping or problem solving applications.  Manufactured to customer specifications they can be made in a limitless range of shapes and sizes. High flexibility in silicone rubber heating blankets can be obtained using tough, robust materials which are finding ever increasing applications in industries.
