Arkema Inc. Adds Kynar PVDF Grades to NSF 61 Listing

Arkema Inc. is adding several grades of its Kynar polyvinylidene fluoride (PVDF) and Kynar Flex PVDF to the National Sanitation Foundation (NSF) 61 listing for potable water applications.  Arkema offers a broad range of both homopolymer and copolymer Kynar resin grades, which vary in melting point, flexural modulus and tensile properties.

arkema0826The range of grades also are suitable for a broad range of manufacturing practices, including  extrusion, injection molding, rotational molding, compression molding, thermoforming, blow molding, solvent casting, thermal induced phase separation (TIPS) and solution phase separation (NIPS) processes.

Kynar PVDF and Kynar Flex PVDF polymers are commonly formed into pipe, tubing, valves, pumps, instrumentation, nozzles, dump tower packing and tanks. Filtration products, which are commonly made of Kynar PVDF, include flat-sheet and hollow-fiber membranes, woven filtration cloth and nonwoven filtration support substrates.

Kynar PVDF is a popular material for construction due to its 150C UL RTI rating, ability to handle low-pressure steam sterilization, chemical resistance to a broad range of cleaning agents, 25/50 ASTM E84 flame and smoke listing for some grades, high abrasion resistance, long-term performance in extreme sunlight and ease of welding and fabrication, according to Arkema.
