Material Introduction

PTFE heat‑shrink tubing is a high‑performance protective sleeving made of polytetrafluoroethylene (PTFE). It features outstanding temperature resistance, chemical stability and electrical insulation. Upon heating, it shrinks tightly to form a tough protective layer against high heat, corrosion, moisture and mechanical wear. Offered in 1.7:1, 2:1 and 4:1 shrink ratios, it is widely used in electronics, electrical, chemical, medical and aerospace industries.

Exceptional High‑Temperature Resistance Continuous operating temperature up to 260°C, withstands short‑term higher temperature exposure. Retains stable dimension and performance without softening, cracking or carbonizing under long‑term high‑heat loads for motors, transformers and high‑temp pipelines.

Excellent Chemical Corrosion Resistance Nearly chemically inert against strong acids, alkalis, solvents, oil and salt mist. Ideal for chemical pipelines, labs and marine scenarios to protect internal cables and components and extend service life.

Superior Electrical Insulation Low dielectric constant and high breakdown voltage prevent leakage and short circuits. Delivers stable insulation for high‑frequency & high‑voltage systems, suitable for electronic parts, sensors, harnesses and high‑frequency cables.

Low‑Friction & Self‑Lubricating Ultra‑low friction coefficient with smooth non‑stick surface. Reduces abrasion and friction loss, perfect for parts with frequent movement or mechanical contact.

Multiple Shrink Ratios for Good Conformability 1.7:1 / 2:1 /4:1 shrink ratios available. Shrinks evenly and fits closely over irregular connectors, bends and complex components for full‑coverage protection.

Global Compliance & Safety Complies with RoHS, REACH, FDA and UL/C‑UL VW‑1 flame‑retardant standards. Meets international safety requirements for export and high‑grade industrial projects.
