PTFE 3D Printer Accessories PTEE Tube Nozzle Tube 1 m 2*4MM Blue

Features： 1. Enhanced with a proprietary high performance additive blend. 2. It is specially developed for 1.75mm consumables with an extremely accurate inner diameter. 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. 4. Excellent acid, alkali and various organic solvents： ASTM D543. High lubricity, non-stick. 5. Widely used in electronics, chemistry, medical and industrial. 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. 7. Excellent anti-adhesion, the inner wall of the tube is not easy to adhere to colloids and chemicals. 8. Excellent aging resistance, can be used outdoors for a long time. 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. 10. Raw materials meet FDA requirements of FDA 21 CFR 177.1550 for food contact surfaces. 11. Excellent electrical performance and long life. Specifications： Length： 1m ID： 1.95mm+-0.05mm Outside Diameter： 4.0mm For： 3D Printer Heat exchanger Valve core Chemical raw materials, pharmaceutical intermediates, transport of corrosive substances High and low temperature liquid, gas delivery Various electronic, insulation of communication components, insulation protection.
