1. Chemical inertness: tubes show excellent resistance to almost all chemicals (including strong acids, strong alkalis, organic solvents, etc.), and not corrode or dissolve due to contact. 2. High temperature resistance: It can maintain stable physical and chemical properties in a wide temperature range of -240°C to +260°C, and the long-term use temperature can reach 200°C. 3. High lubricity: The internal friction coefficient is extremely low, and the resistance of the fluid when flowing in the tube is small, which is suitable for conveying viscous or high-purity fluids. 4. High tensile strength: It can withstand a certain external tensile force without breaking easily. 5. Good flexibility: It is easy to bend and install, and can adapt to various complex pipeline layouts. Heat resistance: Maximum temperature 260℃ Applicable to most models using 4mm outer diameter tube Due to different batches, there may be differences in product appearance and printed text, which not affect use Colour:White Material:PTFE Package Contents: 1 x PTFE Polytetrafluoroethylene Tube Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
