High Shrink Ratio Heat Shrink Tube
High-Shrink Ra o HS Tube (GMW 5x) is manufactured from high quality cross inked polyolefin material.
Features & Benefits
- High shrink ra o up to 5:1
- Optional hot melt adhesive lining for complete environmental protection and insulation
- Excellent resistance to weathering, UV rays, chemicals and solvents
- Meets RoHS Compliance | Halogen Free
- Meets IP 68 (Ingress Protec on)
Applications
- Ideal for applications where there is a large dimensional difference between the cables, connectors and components.
- Enables the Tube to cover the large-size transi ons between cables, cable connectors and back shells, thus simplifying repairs of damaged cable as well as sealing the back end of the connectors.

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.
