Feature: 1. Silicone Rubber Exterior: The heating pad uses silicone rubber as the insulator on the outside and nickel chrome alloy wire as the electric heating on the inside, which can be in close contact with the object being heated. 2. Dielectric Strength: The heating pad has excellent dielectric strength and high heat transfer efficiency, so you can achieve fast heating and quickly provide heat to where it is needed. 3. Light Weight: The heating pad is thin, light weight and flexible, you can adjust this heating pad to the right condition according to different usage. 4. Safe Use: Our heating pad is very convenient and safe to use, with a maximum temperature resistance of 250℃, which can be used for a long time. 5. Applicable Scenes: This heating pad can be used for the insulation of industrial equipment pipes and tanks, and also for the insulation of many instruments, which can be directly wrapped around the surface of the heated object when used.
