2:1 PVDF Heat Shrink Tubing 175°C High Temperature Insulation Sleeve for Wire Protection

175°C High-Temperature PVDF Heat Shrink Tubing for Demanding Circuits

When a circuit runs hot, ordinary polyolefin insulation quickly reaches its limit. Our 2:1 PVDF heat shrink tubing is produced from modified polyvinylidene fluoride (PVDF) resin through precision extrusion and electron-beam cross-linking, forming a semi-rigid, thin-wall and transparent sleeve that keeps protecting conductors where standard tubing fails. With a continuous operating temperature of -55°C to 175°C and a short-term peak of 200°C, it is engineered for high-temperature wire, busbar and component protection.

Why Choose PVDF

PVDF combines outstanding thermal stability with exceptional mechanical and chemical toughness. The material resists abrasion, cut-through and attack from most industrial oils, fuels, solvents and chemical reagents, while its high dielectric strength guards against electrical breakdown. That combination makes the tubing ideal for fully or partially insulated wires, busbars, component leads and other electrical assemblies that must survive heat, friction and aggressive environments.

Key Specifications

Performance Highlights

• Excellent dielectric strength with good flame retardancy
• Semi-rigid, thin-wall and transparent for easy visual inspection
• Superior abrasion, cut-through and chemical/solvent resistance
• Stable electrical and mechanical performance over a very wide temperature range

Typical Applications

The tubing is widely used for high-temperature wire harnesses, busbar insulation, component lead protection and general electrical assembly insulation in home appliances, instrumentation, automotive and industrial equipment. Its transparency also supports clear identification and quality inspection after assembly, while the 2:1 shrink ratio gives a tight, secure fit over connectors and splices.

Standards and Compliance

Every batch is controlled to RoHS 2.0, UL224 and REACH requirements. The electron-beam cross-linking process produces a consistent, void-free wall and predictable recovery, so engineers can specify the sleeve with confidence for certified end products. Dimensional tolerances and shrink performance are held to tight limits from one production run to the next.

Installation Notes

Simply slide the sleeve over the substrate, then apply even heat with a hot-air gun until recovery begins at 150°C and completes at 175°C. Avoid prolonged exposure above the 200°C short-term peak to preserve material properties. Proper heating results in a smooth, tight, insulation-grade covering that resists vibration, moisture and chemical contact over a long service life.
