| VESTAMID Terra HS18-GF30 is a glass-fiber reinforced, heat stabilized, medium viscosity PA 610 compound for injection molding application. The material contains about 30% glass fibers, an ageing protective agent and processing aid for a fast and even form filling. The carbonamide groups (-CO-NH-) of the polyamides form hydrogen bridge bonds between the chains of the macromolecules, thereby substantially promoting crystallinity and increasing their strength, melting point, resistance to chemicals and even water absorption. This is characteristic of all semicrystalline polyamides. Because of its semi-crystalline morphology VESTAMID Terra HS18-GF30 provides a high impact strength, excellent chemical resistance (e.g. against greases, oils, alkalis and saline solutions), a low coefficient of friction and high abrasion resistance. Properties of VESTAMID Terra HS18-GF30 vary little with hanging humidity due to their low moisture absorption. VESTAMID Terra HS18-GF30 is supplied as cylindrical granules, ready for processing, in moisture-proof bags. VESTAMID® Terra HS is the polycondensation product of 1,6-hexamethylene diamine (H) and 1,10-decanedioic acid (sebacic acid—S). Because sebacic acid is extracted from castor oil, VESTAMID® Terra HS is based on natural, renewable resources up to 62%. |
