Biopolymers

VESTAMID® Terra is a new group of polyamides based on renewable raw materials. VESTAMID® Terra is manufactured from the castor bean (Ricinus Communis) and its oil derivatives. This is then synthesized into monomers and forms the basis of the VESTAMID® Terra product range. These Biopolyamides are long-lasting, durable high-performance polymers which can be used in a variety of technically demanding applications. VESTAMID® Terra material is typically processed using injection moulding and extruded to produce fibres and films.

AVAILABLE GRADES

Vestamid Terra DD (PA1012)

VESTAMID® Terra DD is partly based on renewable raw materials and in general has the highest performance of all the bio-based polyamides. Technically speaking, VESTAMID® Terra DD is similar to other high-performance long-chain polyamides such as PA 12 and PA 11. It shows a very high impact strength and heat resistance. Due to its semi-crystalline morphology, VESTAMID Terra DD provides an excellent chemical resistance, e.g., against greases, oils, fuels and hydraulic fluids. It is the best choice in applications where stiffness and impact strength are required.

VESTAMID® Terra DD (PA 1012) at a glance:
  • 45 -100% based on bio-renewables
  • Carbon Footprint: 5.2 kg CO2eq.
  • High dimensional stability
  • Very low water absorption so that the mechanical properties are scarcely affected by changes in atmospheric humidity
  • High impact resistance especially at low temperatures
  • Heat resistance
  • Excellent chemical resistance
  • For use at high temperatures
  • Transparent; in contrast to other semi crystalline polyamides, it can therefore be processed to films with good transparency
  • Fills a position comparable to PA 12 and PA 1212

Vestamid Terra DS (PA 1010)

VESTAMID® Terra DS is 100 percent natural and in many applications outperforms the niche long-chain nylons. VESTAMID® Terra DS is semi crystalline, which is the reason for its high mechanical resistance and chemical stability. It absorbs only little water. As a result its mechanical properties vary little when exposed to changing environmental humidity, and the material features a high dimensional stability. Because of its chemical and physical properties, and the plant origin of its monomers, VESTAMID® Terra DS is an interesting addition to conventional longer-chain polyamides, and it also meets the growing demand for materials made from renewable raw materials.

VESTAMID® Terra DS (PA 1010) at a glance:
  • 100% based on bio-renewables
  • Carbon Footprint: 4.0 kg CO2eq.
  • 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

Vestamid Terra HS (PA 610)

VESTAMID® Terra HS is partly based on renewable raw materials and fills the performance gap between the commodity and the niche long-chain nylons. Technically speaking, VESTAMID® Terra HS occupies a position between the high- performance polyamide 612 and the standard polyamides PA 6 and PA 66. VESTAMID® Terra HS is semi crystalline and thus has high mechanical resistance and chemical stability. Due to its higher melting point, VESTAMID® Terra HS has the highest heat deflection temperature of VESTAMID® Terra series.

VESTAMID® Terra HS (PA 610) at a glance:
  • 62% based on bio-renewables
  • Carbon Footprint: 4.6 kg CO2eq.
  • 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
