Feature: 1. Better Design: The outside adopts silicone rubber as the insulator, and the inside adopts the alloy wire as the electric heating elements, so that it can be in close with the heated object. 2. Quick Heating: Thin, light and flexible. With excellent dielectric strength, fast heating and heat transfer efficiency, it can quickly deliver heat to where it is needed. 3. Work: Convenient and to use, has a service life of up to four years, a thickness of 1.5-2mm, and a maximum temperature of 200℃. 4. Practical Use: Can be used for mixed insulation in industrial equipment pipelines, , etc., and can be directly wrapped on the 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. How to Use: After taking out the product, connect the product to the power supply and it can be used.
