NHF

nhf

NHF is aflexible heatshrinkable sleeving with a low toxicity index. It combines low smoke and acid gas emission with good mechanical and fluid resistant properties. The tubing is especially designed for use in fire safety applications; insulation and protection of cables, harnesses and electrical components used in enclosed spaces. NHF complies with Def. Std. 59/97 Issue 3 Type 8.
