FEP plastics, the best chemical resistance for versatile parts<\/h1><\/div>

FEP material is a fluoropolymer commonly used in tubes or injected parts, with high chemical resistance restraint and is found as an injected part or as tube.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

FEP plastics offers performance near that of PTFE<\/h2><\/div>

FEP, Fluorinated ethylene propylene, is a copolymer of tetrafluoroethylene (the base component of PTFE) and hexafluoropropylene, and as such is part of the fluoropolymer family. The structure is near that of PFA, without oxygen atoms: a CF3 group is bonded on some carbon atoms of the polymer chain. Thus FEP is only based on carbon-carbon and carbon-fluorine bonds, just like PTFE, and is the only fluoropolymer matching PTFE\u2019s chemical resistance. It is resistant to nearly all chemicals, except molten alkali metals, gaseous fluorine, and some complex halogenated compounds.<\/p>\n

FEP has a much lower melting point than PTFE, at 260\u00b0C, and its recommended maximum operating temperature is 205\u00b0C.<\/p>\n

FEP is also slightly more rigid than PTFE and offers less flexlife.<\/p>\n

One important asset of FEP is its high transparency. FEP is amongst the clearest fluoropolymers. It is therefore commonly used in medical applications requiring UV treatment of fluids.<\/p>\n<\/div>\n

FEP is injection moldable and can be extruded with a few modifications compared to classical processes. This is the main asset of this fluoropolymer. With such processes, FEP is highly competitive for high volume applications. Compared to PTFE, FEP tubes are available with longer lengths per unity. FEP is also an excellent candidate for fluoropolymer injection molding. It offers good mechanical properties. Compared to PTFE, injection molding allows the production of many complex parts and still performing in seemingly high temperatures.<\/div><\/div><\/div><\/div><\/div><\/div><\/div>

        When requiring a transparent high performance polymer, virgin FEP is often the best solution. To improve mechanical resistance, at the cost of losing transparency, FEP can easily be replaced by PFA or you can use standard or custom compound, depending on price, as FEP is usually less expensive than PFA. The best price\/performance ratio in this case depends on the transformation process, the exact performance to be improved, and the impact of fillers. A long experience in fluoropolymers is needed in the decision of right material developments. It requires a strong experience in high performance polymer industry, and is one of 3P assets.<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":4508,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"100-width.php","meta":{"footnotes":""},"class_list":["post-4582","page","type-page","status-publish","hentry"],"yoast_head":"\nFEP -
