Heat-shrink tubing

Series

HFGT

HFGT heat-shrink tubing is made from a polyolefin-based material whose formulation is free of halogens such as cadmium, fluorine and bromine, making it a LOW SMOKE and HALOGEN FREE product.

This formulation was developed specifically to pass technical specification EN 45545-2:2015, the reference standard for materials used in the construction of mass transport vehicles such as trains, trams, metros and buses.
