Our cross-linked modified polyolefin is specifically designed for electrical splices, cable terminations, and joints. Its high-shrink-ratio allows for easy application over irregular shapes and large connectors.
With our cross-linked modified polyolefin, you can expect reliable performance and protection for your electrical connections. Its medium wall thickness ensures durability, while its excellent electrical and mechanical performance guarantees optimal functionality. The high electrical insulation properties provide added safety, and the material's exceptional abrasion and impact resistance ensure long-lasting use. Additionally, it is UV resistant, making it suitable for outdoor applications. The operating temperature range of -55 ºC to 110 ºC allows for versatile usage, and the minimum fully recovery temperature of 120 ºC ensures secure and tight connections.
