Silicone heat-shrinkable tubing is fabricated from silicone rubber with excellent heat resistant and mechanical properties. . The inner diameter shrinks by about 50% simply by heating. Silicone heat-shrinkable tubing is used for insulation, protection, and sheathing applications. These rubber tubings have superior heat and cold resistance, flexibility, and electrical insulative properties. They typically maintain their performance characteristics over a wide temperature range, from -50°C to +180°C.
