Feature:1. Better Design: The outside adopts silicone rubber as the insulator, and the inside adopts the nickel chromium alloy wire as the electric heating elements, so that it can be in close contact with the heated object.2. Quick Heating: Thin, light and flexible. With excellent dielectric strength, fast heating and perfect heat transfer efficiency, it can quickly deliver heat to where it is needed.3. Reliable Work: Convenient and safe to use, has a service life of up to four years, a thickness of 1.5-2mm, and a maximum temperature resistance of 200.4. Practical Use: Can be used for mixed insulation in industrial equipment pipelines, tanks, etc., and can be directly wrapped on the surface of the heated object when used.5. 4Pcs in Total: There are 4pcs silicone heating mat in the set, which will meet your working needs with high work efficiency.Specification:Item Type: Heat MatMaterial: SiliconeProduct Size: Approx. 50 x 50mm / 1.97 x 1.97inLine Length: Approx. 0.3m / 0.98ftVoltage: DC 12VPower: 7.5wHeating Temperature: 120-150Heat Resistant Temperature: 200Resistance Density: 2W/cm.
