Product Specification

PFA High-Transparency Heat Shrink Tubing

Premium Protection for Industrial Rollers & Precision Components (-70°C ~ 260°C)**

Product Overview

Clear as glass. Strong as armor.
This industrial-grade PFA Heat Shrink Tubing is engineered for extreme chemical environments and high-temperature processes. As a premium member of the Teflon™ fluoropolymer family, PFA (Perfluoroalkoxy) inherits PTFE’s exceptional chemical resistance and thermal stability, while offering superior transparency, lower gas permeability, and enhanced weldability.

Whether you are coating industrial rollers, protecting semiconductor fluid lines, insulating precision electronics, or reinforcing medical instruments, PFA heat shrink tubing provides unmatched reliability and purity.

Key Benefits

1.  Ultra-High Transparency (Crystal-Clear Visibility)

Unlike the milky appearance of PTFE shrink tubing, PFA offers nearly glass-like clarity.
✓ Visual inspection without disassembly
✓ Easily monitor fluid flow, cable condition, or roller surface
✓ Ideal for laboratory, cleanroom, and online monitoring systems

2. Exceptional Chemical Resistance

PFA is completely inert to almost all chemicals, including:
✓ Aqua regia & hydrofluoric acid
✓ Strong acids & strong alkalis
✓ Organic solvents
✓ Oxidizing & reducing agents

Zero corrosion. Zero swelling. Zero degradation — even under long-term exposure.

3. Lower Gas Permeability (Better than PTFE)

Due to its denser molecular structure, PFA provides significantly superior barrier properties:
✓ Reduced vapor penetration
✓ Enhanced protection for sensitive components
✓ Ideal for corrosive gas, acid fog, and high-purity environments

4.  Wide Operating Temperature Range (-70°C to +260°C)

Engineered for harsh thermal conditions:
✓ No cracking in deep-cold environments
✓ Continuous performance at 260°C
✓ Flame rating: VW-1 (self-extinguishing)

Perfect for shrink-fit applications, roller coating, and electrical insulation.

5. Biocompatible & High Purity

PFA is non-toxic and exhibits excellent biocompatibility with extremely low extractables.
✓ Medical insulation
✓ Pharmaceutical fluid handling
✓ Analytical and precision instruments
