NH
is a halogen free, flame retarded, flexible, heat-shrinkable
polyolefin tubing that |
| |
has
excellent flame retardancy with reduced acid gas emission
and |
| |
smoke
generation. |
| |
NH
is recommended for use in environments where safety is an
important |
| |
consideration,
in case of fire or overheating of electrical circuits. |
