HSF is a woven flexible and shrinkable sleeve made of polyester multifilaments and irradiated modified polyolefin monofilaments. Heated above 110°C, the HSF sleeve shrinks and provides tight fit around the pipe to protect, even on narrow radii. It provides outstanding abrasion resistance even in high temperature environment. It can also be used for sound dampening. Very flexible, the HSF sleeve is easy to install on bent Durit® and garantees protection against abrasion, oils, trapped water, heat and humidity.
