Irradiation heat shrinkable materials are important protective materials and the demand in the industrial field continues to increase.

Irradiation heat shrinkable materials are polymer functional materials prepared using ionizing radiation technology. The polymer materials with linear structure are bombarded by ionizing radiation to generate polymer free radicals, which are then rebonded to each other to form a three-dimensional network structure. After the irradiation heat shrink material is heated, expanded, deformed and cooled to…
