VITON - Fluoroelastomer Heat Shrinkable Tubing
Applications
VITON is made of cross-linked fluoroelastomer. It provides optimum performance and reliable protection in high and low temperature and harsh chemical environments, while maintaining a flexible elastic state. It is often used for the wire harness protection in chemical, aviation and automotive industries.
Operating Temperature Range
- Continuous operating temperature: -55℃ ~ 200℃
- Minimum shrink temperature: 150℃
- Full recovery temperature: Above 220˚C
Color
Standard color: black, (Other colors, special sizes, and cut pieces are available on request.)
※VITON is a trademark of E. I. Du Pont De Nemours and Company
Characteristics
- Shrink ratio: 2:1
- Excellent flame retardance
- Excellent chemical resistance
- Flexibility at high and low temperatures without cracking
