Control is the holy grail to successful bending. Most man-made decking is made with at least two different plastics, so having the ability to control the temperature of each Heatingskins unit independently is the biggest breakthrough in bending in decades. Your future artistic creation will be easier than ever as you heat deck boards with confidence and precision! Silicone rubber Heatingskins are extremely versatile and suitable for a large range of environments. Moisture and chemical resistant silicone rubber provides exceptional durability and longevity. The heating elements are laminated between two layers of 20-mil fiberglass reinforced silicone rubber. The high-limit thermostat protects the heater and the contents being heated. A thermocouple probe measures the core temperature of the composite decking material you are heat forming. This allows for superior control, as some materials reach the desired temperature at different intervals of time during the heating process.
