This is a 3:1 heat shrink tubing that is completely halogen-free and exceeds the requirements of the London Underground and MOD. It is recommended for applications where fire protection is paramount, such as in public buildings, public transport, underground passenger transport systems, submarines, hospitals, and airports. The tubing has very low flammability, with a flame temperature index above 350 °C, and complies with LUL standards for extremely low smoke emission with no toxic smoke emission. It has a high oxygen index, above 40%, making it ideal for use in insulation, cable protection, cable markings, and encapsulation on connectors. The package contains 5 black hoses, each 1.2 m long.
