| HWIT-Z Heat-shrinkable halogen-free
heavy-wall tubing |
| |
 |
|
| Features |
| |
- Halogen-free: low smoke, low toxicity and
low acid gas generation
- Flame retardant
- Shrink ratio (Radial change): 3:1, which allows
it easily to fit over irregular shape and large
size connectors.
- Minimum Full recovery temperature: 1 20 ¡æ
- Continuous Operating Temperature: -55 ¡æ ~110
¡æ
- Outstanding physical performance, High resistance
to impact and abrasion
- High insulating strength
- Excellent chemical and solvent resistance
properties
|
|
|
| |
| Application |
| |
For use in cable accessories and as insulating tubing
in hazardous areas where very high material specifications
are required. Provide low smoke, low toxicity and low
acid gas generation while being highly flame retarded
and having low calorific value. |
