High temperature PTFE tube for 3D printers | BESTEFLON

Since engineering grade materials require high continuous temperatures for 3D printers, component requirements are high. Therefore, the 3D printer uses PTFE tube as the feeding tube (feeder tube). PTFE tubes are widely used in the 3D printer industry, mainly because of the following performance:

Non-stickiness: PTFE is inert, almost all substances are not bonded with PTFE tube, and very thin films also show non-stick properties.

Heat and cold resistance: PTFE tube has excellent heat and low temperature resistance. It can withstand temperature up to 300℃ in a short time, and the melting point is 327℃. It will not melt at 380℃. Generally, it can be used continuously between 240℃ and 260℃. It has remarkable thermal stability. It can work at freezing temperature. No embrittlement, cold resistance to 65℃.

3. Lubricity: PTFE tube has a low coefficient of friction. The friction coefficient changes when the load is sliding, but the value is only between 0.04-0.15.

4. Non-hygroscopicity: The surface of PTFE tube does not stick to water and oil, and it is not easy to stick to the solution during production operations. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

5. Corrosion resistance: PTFE tube is hardly corroded by chemicals, and can withstand all strong acids (including aqua regia), strong alkalis, and strong acids except molten alkali metals, fluorinated media, and sodium hydroxide above 300°C. The role of oxidants, reducing agents and various organic solvents can protect parts from any kind of chemical corrosion.

6. Weather resistance: no aging, better non-aging life in plastics.

7. non-toxic: in a normal environment within 300 ℃, physiologically inert, non-toxic can be used for medical and food equipment.

8. Insulation: Very good dielectric constant and high insulation.

9. The friction coefficient is small, and the fluidity of the raw materials is good.

Due to the excellent performance of PTFE hose, it is not only suitable for 3D printer industry, but also widely used in pipeline anticorrosion, high temperature, low temperature and corrosion resistance. And used in harsh environments such as lubrication, electronics, electrical appliances, aerospace and medical treatment.
