Overview

The HTD 2X series is a yellow–green polyolefin heat shrink tube designed for wire marking, cable identification
and neat insulation. Using radiation cross-linked polyolefin, it delivers a stable 2:1 shrink ratio and a clean surface after shrinking.
Typical shrink activation is around 125 °C (initial ~70 °C), compatible with standard hot-air tools.

This polyolefin heat shrink tube features flexible, durable color bands for quick visual identification on
production lines. It is also flame-retardant, making it suitable for safety-critical marking and harness work.

Features

  • 2:1 shrink ratio; radiation cross-linked polyolefin.
  • Operating temperature: −55 °C to 125 °C; initial shrinking ≈ 70 °C; full shrinking ≈ 125 °C.
  • Flame-retardant construction for added safety.
  • Bright yellow–green color for clear cable identification.
  • Convenient to use with oven or hot-air gun; smooth, clean finish.
  • Standard packaging by size (see table below).

For panel builders and OEMs, this polyolefin heat shrink tube simplifies daily marking jobs while providing
durable insulation and strain-relief.
