Heat Shrink is a non-flammable shrink tube which exhibits outstanding chemical and solvent resistance. Its electrical characteristics remain stable over a wide operating temperature range of -70°C to +260°C. The major use of this material is for electrical insulation, protection of electronic components and the covering of hydraulic hose and couplings preventing contamination and corrosion.
