Heat shrink cable accessories are made of rubber/plastic composites. After exposure to radiation, the semi-finished productis heated and stretched to expand its dimension. It is then rapidly cooled in order to keep its shape.
Wheninstalling, the cable accessories will shrink back down to the original dimensions by applying heating because of their“shapememory effect”.
