HP-HST(Viton) Viton Shrink Tubing

Product Details

■ Application:
HP-HST(Viton) is high temperature resistant, solvent-resistant heat shrink tubing. It is made of cross-linked fluoroelastomer compound with superior impact, abrasion and cut through resistance. With superior resistance to high and low temperature, fuids, solvents and corrosive chemical, HP-HST(Viton) is particularly suitable for applications that require heat resistance (such as electric and hydraulic systems near engines and fuel tanks of airplanes and vehicles) and resistance to chemical solvents. It is particularly used in applications require high temperature (200℃) resistance or in chemically exposed environments. It can be used in applications where additional protection against weather, ultraviolet radiation and ozone degradation is needed. It is used for insulation and strain relief on appliances and for protection of electronic components.
■ Characteristics:

● Material: Fluororubber
●Shrink ratio 2:1
● Operating Temp : -65℃--+200℃
●Very flexible, highly flame-retardant
●High temperature resistant up to 200℃
●Excellent high and low temperature resistance
●Excellent abrasion resistance and resistance to oil, diesel and hydraulic fluids.
●Abrasion resistance and excellent mechanical properties
●RoHS and REACH compliant.
