Made from plant (bio-sourced) Reduces global warming potential High performing Competitive against existing polyamides
This is a polyamide produced using sebacic acid (COOH-(CH2)8-COOH) produced from plant-derived castor oil as a raw material, and hexamethylenediamine as a monomer.
Low water absorption and good dimensional stability
High chemical resistance
High resistance to metal chlorides (calcium chloride)
High bending fatigue resistance
Good processability
VESTAMID® Terra HS (PA 610) is produced by polycondenzation of 1,6-hexamethylenediamine (H) and 1,10-decanedicarboxylic acid (sebacic acid, S), the sebacic acid obtained from castor oil. Thanks to its properties, Terra HS is similar to the high-performance polyamide PA 612 and fills a position between this one and the PA 6 and PA 66 standard polymers. It is semicrystalline with a very high mechanical strength and good UV and chemical resistance. Compared to short-chain standard polyamides, it absorbs only low quantities of water. Thanks to its high melting point, it also has the best heat distortion resistance of all Terra products.
