PFA - 260˚C PFA Heat Shrinkable Tubing
Applications
PFA heat shrinkable tubing is made of soluble polytetrafluoroethylene. It has the same low coefficient of friction, chemical resistance and non-stick properties as FEP products, but a higher heat resistance than FEP, allowing it to be used continuously at 260 ̊C. PFA is almost corrosion resistant to all chemical substances and is suitable for anti-stick and chemical resistant applications in high temperature environments.
Operating Temperature Range
- Continuous operating temperature: -65℃ ~ 260℃
- Full recovery temperature: Above 260˚C
Color
Standard color: clear, (Special sizes and cut pieces are available on request.)
Characteristics
- Shrink ratio: 1.25:1
- Excellent flame retardance
- Superior chemical and abrasion resistance
- Ideal insulation property
- High transparency
- Coefficient of friction: 0.1~0.2
