VESTAMID® L – polyamide 12

Evonik is one of the world's largest producers of polyamide 12 (PA 12), which it markets as VESTAMID® L. We benefit here from backward-integrated production: From butadiene as the starting material Evonik produces laurolactam, the monomer for PA12, in a multi-stage process. We are currently building an additional complete production complex, which will increase our capacity by more than 50%.

The concentration of amide groups is lowest in polyamide 12 and determines its special properties.


Evonik's VESTAMID® L compounds comprise a large number of different products tailored precisely to the requirements of processors and end users.

The properties of semicrystalline polyamides are determined by the concentration of amide groups in the macromolecule. This is lower in PA 12 than in all other commercially available polyamides, which accounts for its special properties:

  • Minimal water absorption: molded parts show almost no dimensional changes with variation in atmospheric humidity.
  • Extraordinarily high impact resistance and Charpy notched impact strength, even well below freezing point
  • Good to excellent resistance to greases, oils, fuels, hydraulic fluids, and many solvents as well as to salt solutions and other chemicals
  • Excellent resistance to stress cracking, even for metal parts encapsulated by injection molding or embedded into the plastic
  • Excellent abrasion resistance
  • Low dry sliding friction coefficient as compared with steel, polybutylene terephthalate, polyacetal, and other materials
  • Noise and vibration damping properties
  • Excellent resistance to fatigue caused by frequent load change
  • Easy processability

Thanks to these properties, the applications of VESTAMID® L range from sophisticated line systems for motor vehicles, through large-volume pipes as are used in crude oil production, core insulation in the cable industry, and catheters in medical technology, to precision injection-molded parts like impellers and control-valve housings in machine and equipment manufacture.
