HTS 2X Heat-Shrinkable Tube (2:1)
2:1 shrink ratio, cross-linked polyolefin for clean insulation and bundling.
Flexible, abrasion-resistant, neat finish; typical shrink activation around 125 °C.
Multi-color options (Black/White/Red/Yellow/Blue/Green/Grey) and size range for common electrical harnessing.
- Flame-retardant construction for added safety (this property applies only to HTS 2X & HTD 2X).
Overview
HTS 2X is an electrical heat shrink tube series made of radiation cross-linked polyolefin with a 2:1 shrink ratio.
It provides clean insulation, bundling and strain-relief on wires, terminals and small harnesses, keeping a neat, professional finish.
Typical shrink activation is about 125 °C, compatible with common hot-air tools used by panel builders and OEMs.
The material remains flexible after shrinking and resists cracking; color options support quick identification on production lines.
A comprehensive size list helps standardize inventory for day-to-day assemblies.
HTS 2X is our go-to electrical heat shrink tube for day-to-day wiring insulation and bundling.
The flexible polyolefin material shrinks cleanly and leaves a professional finish on small harnesses and terminals.
Key Features
- 2:1 shrink ratio for broad coverage and easy assembly.
- Cross-linked polyolefin: flexible, abrasion-resistant, clean surface.
- Typical shrink activation ≈ 125 °C; works with standard hot-air tools.
- Neat insulation, bundling, strain-relief, and color identification.
- Standard colors: Black / White / Red / Yellow / Blue / Green / Grey.
- Custom cut lengths and halogen-free options available on request.
