FAQs
1. What is a Heat Shrink Shroud?
A Heat Shrink Shroud is a protective sleeve made from cross-linked polymer material that shrinks when heat is applied. It provides insulation, sealing, and mechanical protection for cables, joints, and terminations.
2. How does a Heat Shrink Shroud work?
When heat is applied using a heat gun or torch, the shroud shrinks uniformly and tightly wraps around the cable or joint, creating a secure and sealed covering.

3. What material is Heat Shrink Shroud made of?
It is typically made from cross-linked polyolefin material, often containing carbon black for UV resistance and weather protection.
