DUWAI DWTON - Fluoroelastomer Heat Shrinkable Tubing
APPLICATIONS
DWTON 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.)
- Shrink ratio: 2:1
- Excellent flame retardance
- Excellent chemical resistance
- Flexibility at high and low temperatures without cracking
