High-Temperature Heat Shrink
For demanding thermal environments in automotive, industrial, power electronics and sensor-routing applications.
Technical Data
Catalog-based heat shrink tubing parameters
These ranges summarize the main heat shrink families shown in the WCW catalog and help buyers compare shrink ratio, temperature class and sealing structure.
General Polyolefin Series
Standard insulation and harness-marking projects usually start from the common polyolefin series with multiple shrink ratios.
- Main shrink ratios: 2:1 / 3:1 / 4:1
- Typical use: harness insulation, connector covering, terminal bundling
- Qualification direction: UL224 / RoHS according to selected model
- Selection focus: supplied diameter, recovered diameter and wall build
Halogen-Free and 150C Series
For cleaner material requirements or higher continuous service temperature, the catalog lists halogen-free low-smoke and 150C options.
- Halogen-free 2:1: initial shrink >=80C, full shrink >=125C
- Halogen-free operating range: -55C to +125C
- 150C tubing: initial shrink >=84C, full shrink >=135C
- 150C operating range: -55C to +150C
- Reference compliance: RoHS / IPC or equivalent project requirement discussion
Dual-Wall Adhesive Series
Preferred for waterproof sealing, anti-corrosion protection and air-tight wrapping around irregular connector exits and joints.
- Main structures: 2:1 / 3:1 / 4:1 dual-wall adhesive tubing
- 2:1 adhesive type: initial shrink >=70C, full shrink >=125C
- Typical operating range: -45C to +125C
- Project strengths: waterproofing, corrosion resistance, sealing and UV resistance by model
- Common applications: automotive harnesses, battery packs, terminals and outdoor cable joints
If you send the target recovered diameter, supplied diameter, shrink ratio and whether adhesive sealing is needed, WCW can help narrow the correct tubing family more quickly.
FAQ
Common buying questions
What should I provide for a replacement project?
Share the target brand or model, recovered size, supplied size, adhesive or sealing need, operating temperature and end-use application so we can narrow the correct tubing family faster.
Do you support battery pack and automotive harness projects?
Yes. This series is commonly used for battery-pack harnesses, terminal sealing, connector protection and sensor-branch protection in automotive and energy storage projects.
Can you send samples before mass quotation?
Yes. We can arrange samples first so your team can validate fit, shrink behavior, sealing effect, installation process and replacement feasibility before mass ordering.
Can you help compare shrink ratios and wall structures?
Yes. We can recommend the suitable ratio and whether single-wall, dual-wall or special high-temperature structure is more appropriate based on sealing target, wall build and assembly space.
