Teflon (PTFE) Heat-Shrink Tubing for High Temperature and Chemical Duty
Shrink PTFE for chemically aggressive and high-temperature service. PTFE shrink tubing serves where nothing else survives: continuous heat to ~260 degC and almost total chemical resistance. We supply it for sensor, lab and process duty. Expanded (FEP-like recoverable) PTFE is used where a true recovery is needed; we match the grade to the process fluid and temperature.

Applications by industry
- High-temperature and chemical-duty wire sleeving
- Semiconductor and lab instrument cable protection
- Heater and thermocouple lead insulation
- Capacitor and coil lead isolation tubing
- Low-friction conduit for moving wires
- Tight-diameter shrink over sensors and probes
Why PTFE / FEP heat-shrink for this application
PTFE shrinks over wires to give durable high-temperature, chemical-proof insulation with low outgassing for instruments that other polymers can't survive.
p>Shrink temperature is high; protect adjacent components. FEP shrinks easier than PTFE, confirm which your duty actually needs.Standards: UL 224, ASTM D3294, MIL-I-23053 (PTFE shrink class).
Feature and remaining-wall review
For Teflon (PTFE) Heat-Shrink Tubing we sinter ID and OD to size and CNC turn the ends, slots and holes. PTFE cuts cleanly only with sharp tooling. Review of feature depth, edge distance and remaining wall happens against critical geometries, and the drawing is what confirms capability, not a general tolerance.
Inspection and traceability
We state the control plan with you. Batch traceability links raw material lot to finished part.
- First-article inspection (FAI) per your plan
- In-process dimensional checks at every station
- Batch certificate of conformance (COA) supplied on request
- Lot traceability to incoming material certificate
- Dielectric strength and insulation resistance testing available on request
