Summary for nylon pa12 data Discussion
Nylon PA12 data is the focus_keyphrase here, and Petter Haug asked where to find a material datasheet for NYLON PA12 and whether it could be compared with PTFE for use as a soft seat insert material in valves. Garry Taylor replied that PA12 is manufactured by EMS Grivory under the brand name Grilamid, and noted that TR grades are transparent. He also pointed to an alternative brand, Trogamid, made by Degussa-HPP, and suggested searching the manufacturers’ websites for more information. The thread does not provide a direct technical comparison of PA12 versus PTFE or a list of advantages and disadvantages for valve seat use, only sources for product data and brand names to investigate further.
Q. Where can I find a material datasheet for NYLON PA12? I need it to compare this material to PTFE, is there anywhere I can find advantages/disadvantages for use of NYLON PA12 as soft seat insert material for valves?
Best regards,

A. PA12 is manufactured by EMS Grivory (their website is – emsgrivory – do a search for it) under the brand name Grilamid.
TR grades are transparent.
An alternative brand is trogamid (manufacturer: Degussa-hpp)
Hope this helps.
