■ Application:
HP-HST(DR) is flexible, flame-retardant Diseal-Resistant elastomer heat shrinkable tubing. It is made of irradiation cross-linked specially formulated flexible elastomeric compounds. With resistance to aviation and diesel fuels, hydraulic fluids, and lubricating oils, DR is ideal for applications require resistance to fuels, fluids and solvents. It is particularly suitable for protecting and bundling of high-performance cables and wiring harnesses.
■ Characteristics：
●Material: Elastomer
●Shrink ratio 2:1
●Operating range : -75℃--+150℃
●Flammability : VW-1
●Outstanding fluid and heat resistance
●Abrasion resistance and excellent mechanical properties
●Excellent resistance to oil, diesel and hydraulic fluids.
●RoHS and REACH compliant.
