Model: JY-TL, JY-TT, JY-TS
Teflon sleeve is made of polytetrafluoroethylene (PTFE) material, which has high temperature resistance (260℃), corrosion resistance, high insulation, high strength and other characteristics. Products are used in important science and technology industries such as electronics, computers, electric heating, aerospace, military and communications, such as miniature transformers, special sensors, artificial blood vessels
Density: 2.16-2.20 g/cm3 Volume resistance > 1×1018
Surface resistance > 2 × 1013, arc resistance > 165 seconds without leakage
Low water absorption: water absorption < 0.1% Minimum friction coefficient: minimum friction coefficient
Surface does not stick: known hard material heads cannot stick to the surface
Non-flammability: does not burn in air and meets areas with strict fire protection requirements
Non-toxic: non-toxic and tasteless, with physiological inertness, without any harm to people and the environment
