Silicone heat shrinkable tubing is a high-quality, general-purpose heat shrinkable tubing manufactured through a special formula process. It also has high temperature resistance, low temperature resistance, chemical corrosion resistance, high insulation, high flame retardancy, high shrinkage, environmental protection, and softness. and weather resistance, and can be used to organize wiring harnesses and provide insulation protection. Product performance: A new type of heat shrinkable product mainly used for insulation, protection, coating, etc. of electronic components. After heating, the inner diameter of the casing quickly shrinks to half, tightly wrapping the protected electronic components within the casing without being affected by the external environment. The biggest advantage over ordinary heat shrink tubing is its high temperature resistance, which can be as high as 200 degrees Celsius.
Application fields: Silicone heat shrinkable tubes are often used in medical equipment, household appliances, aerospace, military industry, automobiles, electronic components, transformers, engines and other fields that have certain requirements on product flexibility and temperature resistance to provide insulation protection for wires and cables. . Compared with ordinary casing, it has better high temperature resistance, high pressure resistance and insulation performance.
