Features: <br>1. Enhanced with a proprietary high performance additive blend. <br>2. It is specially developed for 1.75mm consumables with an extremely accurate inner diameter. <br>3. 1.9mm ± 0.05mm inner diameter reduces the "swing space" or bending inside the tube, allowing flexible filaments to be printed even on the longest Bowden system. <br>4. Excellent acid, alkali and various organic solvents: ASTM D543. High lubricity, non-stick. <br>5. Widely used in electronics, chemistry, medical and industrial. <br>6. Low friction coefficient: The friction coefficient is generally only 0.04, which is a very excellent self-lubricating material, and the friction coefficient does not change with temperature. <br>7. Excellent anti-adhesion, the inner wall of the tube is not easy to adhere to colloids and chemicals. <br>8. Excellent aging resistance, can be used outdoors for a long time. <br>9. Excellent electrical insulation properties: PTFE is a highly non-polar material with good dielectric properties, great electrical resistance, and a dielectric constant of about 2.0, which is small in all electrical insulating materials. <br>10. Raw materials meet FDA requirements of FDA 21 CFR 177.1550 for food contact surfaces. <br>11. Excellent electrical performance and long life. <br> <br>Specifications: <br>Length: 1m <br>ID: 1.95mm±0.05mm <br>Outside Diameter: 4.0mm <br>Color: Blue, Red Optional <br>For: <br>3D Printer <br>Heat exchanger <br>Valve core <br>Chemical raw materials, pharmaceutical intermediates, transport of corrosive substances <br>High and low temperature liquid, gas delivery <br>Various electronic, insulation of communication components, insulation protection. <br> <br>Package List: <br>1 * Nozzle Tube1、Enhanced with a proprietary high performance additive blend. <br>2、It is specially developed for 1.75mm consumables with an extremely accurate inner diameter. <br>3、1.9mm ± 0.05mm inner diameter reduces the <br>4、Excellent acid, alkali and various organic solvents: ASTM D543.
