The ST series is a heat-shrinkable rubber tube that can easily contract to 1/2 its internal diameter with heat application.[Features]· Excellent heat and cold resistance, and flame retardancy: can be used in a wide range of temperatures ranging from +200°C to -50°C. Also has UL standard compliant superior flame retardancy.· Excellent electrical characteristics: displays stable electrical characteristics even under harsh conditions.· Suitable flexibility: even after heat shrinking, the silicone rubber does not lose its pliability and is strongly resilient to age degradation.· Superior molding: The molding properties of silicone rubber can be utilized for masking and resin molding of jigs.· Superior airtight coating: A coating is applied to deal with the contractive stress of rubber, enabling a superior airtight seal.· Range of sizes: From small to large aperture, products with various opening diameters and thicknesses are available.
