Fluorinated plastics (Halar® ECTFE, Hylar® PVDF, Hyflon® MFA/PFA, Algoflon® PTFE) are extruded or molded into pipes, valves, pumps and fittings for use in chemical process equipment when excellent temperature and chemical resistance are required. Small pieces can economically be made entirely of fluoropolymers. Extruded or molded components include tubes, pipes, hose, column packing, pumps, valves, fittings, gaskets, and expansion joints. Certain heat exchangers, used in very acidic media, have entire components made of MFA or PFA.
Hyflon MFA, Halar ECTFE, and Hylar PVDF tubing is designed for fluid handling applications requiring a pure material with excellent chemical and high temperature resistance.
The surface of Hyflon MFA perfluoropolymer is up to 10 times smoother than standard PFA, improving cleanliness, reducing pressure drop, and reducing wall build up in problematic slurries or mixtures. Hyflon MFA is designed to give much better physical properties than FEP, lower creep and improved stress cracking resistance. Like PFA, Hyflon MFA offers the highest temperature rating and broadest chemical resistance of all melt processable fluoropolymers. MFA has a continuous use temperature of 250°C.
Halar ECTFE and Hylar PVDF are excellent choices for all high purity water applications.
Algoflon® PTFE has outstanding chemical inertness in aggressive environments, thermal resistance, electrical properties, and non-stick characteristics in a wide range of temperatures from cryogenic to 260°C. This makes Algoflon PTFE the ideal material for many critical applications. In particular, Algoflon DF powders are currently used for the production of pipe and tubing by past extrusion meeting the demanding requirements of the chemical industry.
