VESTAMID® Terra
Because we careTechnical biobased polyamides which
achieve performance by natural means
Evonik Industries AG has recently developed andis pushing a new line of bio-based polymers
under the existing family trade name
VESTAMID®. There are currently three products
within this new group of polyamides available
that are partially or entirely based on renewable
feedstocks:



VESTAMID® Terra HS (PA610)
VESTAMID® Terra DS (PA1010)
VESTAMID® Terra DD (PA1012)

Ricinus communis, the castor bean plant grows
in arid area, hence its cultivation neither affects
food production nor does it cause land usechange. The monomers used in the Vestamid®
Terra line are derived from castor bean oil.
The VESTAMID® Terra products are available inpellet form as a base polymer. Our expertise isto provide tailored solutions for specificapplication fields. This has lead to thedevelopment of a wide range of compounds
which can contain, e.g. various stabilizers, flame
retardants, fiber reinforcements, colouring
agents, etc. Detailed information can beobtained upon request.

Terra HSVESTAMID® Terra HS is partly based on
renewable raw materials and fills theperformance gap between the commodity andthe niche long-chain nylons.

Technically speaking, VESTAMID® Terra HS
occupies a position between the highperformance polyamide 612 and the standard
polyamides PA 6 and PA 66.

VESTAMID® Terra HS is the polycondensation
product of 1,6-hexamethylene diamine (H) and1,10-decanedioic acid (sebacic acid—S). Because
sebacic acid is derived from castor oil,
VESTAMID® Terra HS is a material that is partly
based on renewable resources.

VESTAMID® Terra HS is semicrystalline and thus
has high mechanical resistance and chemicalstability. Due to its higher melting point,
VESTAMID® Terra HS has the highest heat
deflection temperature of VESTAMID® Terraseries.

Terra DS
VESTAMID® Terra DS is 100 percent natural andin many applications outperforms the niche
long-chain nylons.
VESTAMID® Terra DS is the polycondensation
product of 1,10-decamethylene diamine (D) and1,10- decanedioic acid (sebacic acid—S).
Because both monomers are derived from castor
oil, VESTAMID® Terra DS is a material that isbased 100 percent on natural resources.
Technically speaking, VESTAMID® Terra DS
occupies a position between the highperformance long-chain polyamides such as PA
12 and PA 1212 and the standard polyamides PA
6 und PA 66, which have a shorter chain length.

VESTAMID® Terra DS is semicrystalline, which is
the reason for its high mechanical resistance andchemical stability. It absorbs only little water. Asa result its mechanical properties vary little when
exposed to changing environmental humidity,
and the material features a high dimensional
stability.
Despite its crystallinity, VESTAMID® Terra DS canbe used to manufacture films with goodtransparency. Compounds based on VESTAMID®
Terra DS have high melting points. In turn, highheat deflection temperatures result, which canbe advantageous for some applications.
Because of its chemical and physical properties,
and the plant origin of its monomers,
VESTAMID® Terra DS is an interesting addition toconventional longer-chain polyamides, and it
also meets the growing demand for materials
made from renewable raw materials.

Terra DD
VESTAMID® Terra DD is partly based on
renewable raw materials and in general has thehighest performance of all the bio-basedpolyamides

VESTAMID® Terra DD depicts 1,12dodecanedioic acid from fossil resources, whereas DD-G depicts the monomer from biomass
resources.

VESTAMID® Terra DD is the polycondensation
product of 1,10-decamethylene diamine (D) and
1,12-dodecanedioic acid (D). The 1,12dodecanedioic acid (D) is typically sourced froma petroleum production route, but can also be
sourced via palm kernel oil. Because bothmonomers can be derived from plant oils,
VESTAMID® Terra DD is a material that is based
45% to 100% on natural resources.

Technically speaking, VESTAMID® Terra DD issimilar to other high-performance long-chain
polyamides such as PA 12 and PA 11. It shows avery 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 inapplications where stiffness and impact strength
are required.
