1.7: 1 /4: 1 PTFE Heat Shrinkable Tubing High Temperature PTFE Heat Shrink Tube

Product DescriptionW-SPTFE 1.7:1 4:1 PTFE Heat Shrinkable TubingPTFE heat shrinkable tubing is made of PTFE with high-temperature performance, chemical resistance, high insulation and excellentmechanical properties. Designed to provide insulation and mechanical protection in severe chemical and thermal environments.Widely used in electronic, aerospace, military and communication fields. Used to cover hydraulic hose and couplings to preventcontamination and corrosion. The high mechanical strength and ex tremely low coefficient of friction make it good for reducingdamage to bearing shafts and similar applications.* Operating temperature: -67ºC ~ 260ºC* Minimum fully recovery temperature: 350ºC* Standard color: Clear* Shrink ratio 1.7:1 4:1* Excellent flammability * High temperature resistant to 260ºC* Excellent physical properties and chemical resistance* RoHS and REACH compliant   PropertyRequirementTest methodTypical data Longitudinal shrinkage ≤10% ASTM D 2671 ≤5% Tensile strength ≥17.3 MPa ASTM D 2671 ≥ 22MPa Elongation at break ≥200% ASTM D 2671 ≥300% Dielectric voltage withstand 2500V,60sec, no breakdown ASTM D 2671 pass Volume resistivity 1015Ω·cm min.
