Introducing our high-quality cross-linked modified polyolefin material, perfect for a wide range of applications. With an operating temperature range of -55ºC to 125ºC, this material is designed to withstand extreme conditions. The minimum shrink temperature of 65ºC ensures easy installation, while the minimum fully recovery temperature of 95ºC guarantees a secure and tight fit.
Our material offers a shrink ratio of 2:1, allowing for efficient use and maximum coverage. It is halogen-free, creating a safe and environmentally friendly environment. Additionally, it is low smoke and complies with "RoHS" and "REACH" regulations, ensuring its quality and safety.
Not only is our material soft and flexible, but it also meets the UL224 VW-1 flammability standard, providing added protection. Its excellent insulation, heat resistance, and voltage performance make it a reliable choice for various applications.
Use our material for identifying wire bundles, cables, wire terminals, and components. The shrinkage process begins at 65ºC and completes at 95ºC, ensuring a secure and durable fit.
Choose our cross-linked modified polyolefin material from Shanghai Wellco International Limited for a reliable and high-performance solution.
