Qu\u2019est-ce que le PCTFE\u00a0?<\/h2>\r\n\r\n\r\n\r\n\r\nLe PCTFE (Polychlorotrifluoro\u00e9thyl\u00e8ne) est un polym\u00e8re \u00e0 base de fluorocarbone. Il offre une combinaison unique de propri\u00e9t\u00e9s physiques et m\u00e9caniques, d\u2019ininflammabilit\u00e9 et de faible capacit\u00e9 de perm\u00e9ation \u00e0 l\u2019humidit\u00e9 et \u00e0 la vapeur par rapport aux autres plastiques. La capacit\u00e9 de r\u00e9sistance thermique et de r\u00e9sistance chimique est inf\u00e9rieure \u00e0 celle du PFA et du FEP, cependant, les caract\u00e9ristiques m\u00e9caniques (en particulier la duret\u00e9) sont sup\u00e9rieures. Il convient pour une utilisation dans la plage de temp\u00e9ratures de -200 \u2103 ~ 150 \u2103, en particulier pour les applications cryog\u00e9niques telles que l'oxyg\u00e8ne, l'hydrog\u00e8ne, l'azote, etc. Le PCTFE pr\u00e9sente de tr\u00e8s fortes performances de r\u00e9sistance aux basses temp\u00e9ratures.\r\n\r\n\r\n\r\n\r\n

Le PTFE offre un si\u00e8ge \u00e0 faible friction, avec une excellente compatibilit\u00e9 avec les supports. Les qualit\u00e9s charg\u00e9es offrent une r\u00e9sistance \u00e0 l'usure et peuvent supporter les charges de si\u00e8ge des vannes de classe sup\u00e9rieure.\r\n\r\n\r\n\r\n\r\n

PCTFE(Polychlorotrifluoroethylene) is a fluorocarbon-based polymer. It offers a unique combination of physical and mechanical properties, nonflammability, and low permeation capability to moisture and steam atmosphere compared to other plastics. The heat resistance and chemical resistance capability are less than PFA and FEP, however, mechanical characteristics(especially hardness) are superior. It is suitable for utilizing in the temperature range of -200\u2103\uff5e150\u2103, especially for cryogenic applications such as oxygen, hydrogen, nitrogen, and more. PCTFE has a very strong resistance performance to low temperatures. Property List of PCTFE Item Color Density Hardness Compressive strength Long-term Temp.

PTFE provides a low-friction seat, with excellent media compatibility. Filled grades provide wear resistance and can support seating loads of the higher class of valves. Butterfly Valve Seats PTFE is one of the Butterfly Valve Seat Materials. PTFE Butterfly Valve Seats Are Available in Pure or Reinforced PTFE to Meet Specific Requirements for Different Working Environments.
