Radiation cross-linked heat shrinkable materials must go through mixing-molding-irradiation-expansion before they can become heat-shrinkable products, and the performance requirements for the materials are relatively stringent. After silicone rubber is added to the outer protective heat shrinkable tube material, due to poor compatibility and poor mechanical properties of the material, cracking occurs during the molding process. If hydroxyl silicone oil is added to the material, the compatibility between the silicone rubber and other components in the outer protective material can be improved, so that the tensile strength and elongation at break of the outer protective material can be increased by more than 50%, which not only solves the problem of It solves the problems existing in the molding process and improves the intrinsic properties of the material to meet the needs of manufacturing radiation cross-linked heat shrinkable tubes.
