Details Of CNC Machining PTFE

  • Teflon is another name for polytetrafluoroethylene, PTFE. 

  • PTFE products are generally referred to as "non-stick coatings". It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. PTFE is resistant to acid, alkali and various organic solvents. It is almost insoluble in all solvents. PTFE is also resistant to high and low temperatures, up to -180°C to 260°C. Its friction coefficient is extremely low, and the friction with steel can reach 0.04, which is close to rolling friction and can be used for lubrication. PTFE is also one of the most corrosion-resistant materials in the world and can resist any organic solvent. The material is soft, difficult to process, easy to deform, and cannot process high-precision parts. Generally used in mechanical design for wear-resistant parts. Such as chain guides, W-shaped seals, etc. It also makes an ideal coating for the lining of nonstick pans and water pipes.

  • Some medical customers have requested Sibai to supply medical parts with PTFE raw material. Sibai offers a variety of brackets to medical customers from black PTFE material. These brackets are used in medical equipment. Therefore, the black PTFE material must comply with FDA requirements. SiBai also requires a third-party Lab agency to do raw material testing, and then they can provide FDA certificate reports too. In this way, we can guarantee the quality of PTFE. We use PTFE sheet material for these brackets. The dimensions of these PTFE sheets are 300mm*300mm*8mm. It can withstand high temperature over 134℃. Because these medical customers will do high-temperature sterilization multiple times a day during the use of these brackets.

  • To be honest, the process of these PTFE stents is not complete, and the processing is also very difficult. But the key is to find suitable and good PTFE raw materials. Appropriate high-quality PTFE raw materials mean high-quality PTFE brackets. Sibai purchased imported PTFE raw materials to ensure the quality of these brackets. 

  • We can also provide machined parts made of PTFE from bars and tubes according to customer needs. Sibai does 100% inspection before delivery. As a result, there are few complaints from medical customers about these components manufactured by Sibai.
