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
