HT 50 Heat Shrink Sleeves

HT50 is superior performance heat shrinkable products designed for corrosion protection on field applied girth-weld joints of buried and exposed steel pipelines operating up to 50°C
50°-type product uses the polyethylene produced by ATOFINA of France and many other auxiliary materials as base materials. The mechanic performance targets such as indentation resistance, impact resistance and tensile strength have reached EN12068 standards. And its aging-resistance and ultraviolet rays-proof performance have met the requirements of ASTMD638 standards.
