Heat shrinkable tubes are available in many different materials. Please choose below between heat shrink tubes made of polyolefin, halogen free polyolefin, elastomer, fluoropolymer (Kynar), FEP, PTFE and TFE (Teflon), silicone and viton. Every material has its own properties. Polyolefin heat shrink tubes are often used for general purpose applications. They are available in many different colours. For rail application there are halogen free polyolefin tube available. Flexible and diesel resistant tubes are made of elastomer. UV-resistant and thin walled heat shrink tubes are often made of fluoropolymer. Heat shrink tubes made of FEP (fluorinated ethylene propylene) can be used for temperatures up to +200°C. Teflon (PTFE and TFE) heat shrinkable tubes combines properties like high temperature, thin wall and chemical resistance. Silicone heat shrink tubes are extremely flexible. For outstanding fluid and temperature resistance we recommend the heat shrink tubes made of Viton.
