2021年7月9日 · 左がPFOAで炭素が8個 右がPTFEで長い鎖状. 摩擦低減剤（FM剤）のPTFE（テフロン）が2021年秋からほぼ使用出来なくなります。. 理由はPTFEに含まれているPFOA（ペルフルオロオクタン酸）と呼ばれる有機フッ素化合物が問題です。. PFOAは現在、オイルの摩擦低
2022年8月8日 · High weather resistance. High quality and high performing material. Low flammability. The chemical resistance of chlorotrifluoroethylene is relatively similar to that of PTFE and PVDF. Although its chemical resistance level is identical to PVDF, E-CTFE outperforms PVDF with its chemical resistance in the alkaline range higher than a pH of 10.

2.Features. 1. Good temperature tolerance,24 working temperature -140 to 360 Celsius degree. 2. Non stick,easy to clear adhesives on the suface. 3. Good chemical resistance:it can almostly
For example ptfe would be great for high temp low force very low friction lubrication. Lithium spreys for things like chains and dryness. Silicone for penetrative use and low temp. PTFE can burnish when applied to electrical connectors causing high resistance. Silicone is a better choice there in my opinion.

Since 1958, Gore has developed products that improve lives. At the center of these solutions is polytetrafluoroethylene (PTFE), a polymer with exceptional properties like high tensile strength, a low dielectric constant, UV resistance and many more. In 1969, the possibilities for PTFE expanded with Bob Gore’s discovery of expanded PTFE, or ePTFE.
