Description: 1. Chemical inertness: tubes show excellent resistance to almost all chemicals (including strong acids, strong alkalis, organic solvents, etc.), and will 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 -240C to +260C, and the long-term use temperature can reach 200C. 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. Specifications: 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 will not affect use Color: White Material: PTFE Size: 5M Package Contents: 1 * 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.
