Product Information Liners All resins used by FUSIBOND are Virgin. All Liner systems are also available in unpigmented food and microchip grades. ® (PFA) Perfluoroalkoxy is virtually inert to all chemicals except elemental fluorine and molten Alkali metals. It has better mechanical properties and does not creep or cold flow like PTFE. Tensile strength is 4000 to 4500 psi. Temperature range from -20F (-29C.) to 500 F. (260C.). Metal requires venting. ® (PTFE) Polytetrafluoroethylene has the same corrosion resistance but is softer and has less strength for a given thickness than our other liners so it requires special design considerations. PTFE because of its micro porosity, has a higher gas permeation rate which can be improved by increasing the liner thickness, which also helps its overall strength. Special attention to piping alignment and torquing of the flange bolts may keep creep and cold flow to a minimum. Tensile strength apx. 3000 psi. Temperature -20F. (-29C.) to 450 F. (232 C.) metal requires venting. ® (ETFE) Ethylene Tetra Fluroethylene is a fluoropolymer with superior physical properties and chemical resistance approaching that of PTFE and PFA. It is excellent where high pressure, vacuum, cold flow, or joint creep is a problem. Tensile strength is apx. 6700 psi. Temperature range is -20 F. (-29 C.) to 311 F. (155 C.). Metal is not vented and fittings are Fusion Bonded. Halar® (ECTFE) Ethylene ChlorotriFluoroethylene is a fluoropolymer with exceptional properties. It has by far the best combination of chemical resistance and toughness of any lining we offer. It's superior where temperature cycling, mechanical stress, abrasion, or permeation are a problem. Tensile strength is typically in the 6000 to 7000 psi range. Temperature range is -20F (-29 C.) to 300 F. (149 C.) Metal is not vented. Kynar® Flex(PVDF) Polyvinylidene Fluoride has excellent mechanical properties and is resistant to most chemicals. Tensile strength is 4500 to 6000 psi. Temperature range is -20 F. (-29 C.) to 275 F. (135 C.) metal is not vented. Polypropylene(pp) Has a proven chemical resistance in a wide variety of applications and because it's a copolymer it can be used from -20 F. (-29 C.) to 225 F. (107 C.) mechanical properties are good and tensile strength is generally in the 4000 to 4500 psi range. Metal is not vented. High Density(HDPE) The least expensive of all our liner systems. Good in abrasive service and where PP has a problem stress cracking in HCL. Tensile strength. Temperature Range -20 F.
