PTFE Heat Shrink Tubing (also named teflon heat shrink tube ) helps extend product life by providing a protective covering
that resists heat, shock, corrosion, moisture and other extremes. They have excellent surface lubricity and high dielectric
strength. They are water resistant, chemically inert, and can be produced in a number of custom sizes with a range of
shrink ratios.
