Under the name VESTAMID® Terra Evonik markets a group of new polyamides based on renewable raw materials: The monomers are obtained partly or entirely from castor oil.

The castor oil plant is widespread throughout tropical regions.
The castor oil plant is widespread throughout tropical regions.

VESTAMID Terra is made from castor oil. This means that VESTAMID Terra is up to 100% bio-based. The castor bean plant grows mainly in dry areas and is neither foodstuff nor animal feed. VESTAMID Terra is also a high-performance polymer for demanding applications.

Unlike other biobased polymers, the 610 and 1010 biopolyamides produced by Evonik are high-performance polymers. They are not disposable, have no time limit on use, and have no technical weaknesses compared with equivalent products of fossil origin. VESTAMID® Terra biopolyamides are durable, long-lasting and offer demanding applications, for example, in the automotive or textile industries. Typical fields of application are extrusion, injection molding, fibers, powders, and films.

The name VESTAMID® Terra includes PA 610 and 1010 grades with different property profiles, which fill the gaps in the previously accessible property spectrum of the polyamides.

VESTAMID® Terra HS (PA 610)

  • 62% based on bio-renewables
  • Very high mechanical strength
  • Good UV and chemical resistance
  • Excellent heat distortion resistance
  • Low water absorption compared to standard short-chain polyamides
  • Fills a position between mass polyamides such as PA 6 or PA 66 and long-chain niche products

VESTAMID® Terra DS (PA 1010)

  • 100% based on bio-renewables
  • High mechanical strength
  • Good UV and chemical resistance
  • Low water absorption so that the mechanical properties are scarcely affected by changes in atmospheric humidity
  • For use at high temperatures
  • High translucency; good transparency with thin walls
  • Fills a position similar to that of the long-chain high-performance polyamides PA 12 and PA 1212
