Nylon 12

Engineering Plastic

Nylon 12 (PA12) Engineering Plastic

A high quality engineering plastic material; the chemical name is polyamide 12. It’s available in a range of grades and forms to suit many applications.


While not as fine as Acetal, the machinability of un-modified Nylon 12 is good. Glass-filled grades will require the use of tipped tooling. As with all plastic materials, experience has shown that extra care must be taken with larger diameters, especially in the colder months when plastic materials lose some of their toughness and so have less resistance to machining stresses. So it’s important that these materials are not machined while in a chilled condition. Full machining instructions may be supplied on request.

Chemical Resistance

Nylon 12 is highly resistant to hydrocarbons, alkalis, fats, oils, fuel, ethers, ester and ketones. Not resistant to halogens, mineral acids and certain organic acids, oxidising agents.

Typical Applications

Commercial applications for this engineering material include:

  • Sealing and dampening elements,
  • Mechanical and equipment engineering
  • Bearing and gearbox components
  • Housings and covers
  • Vehicle construction
  • Quick-disconnect couplings for fuel lines
  • Low maintenance parts
  • Vibration dampening

We stock Nylon 12 (PA12) in round bar, plate, sheet and hollow bar.
