Chinese compounder Kingfa Sci. & Tech. Co. (Guangzhou) has been supplying polyamide 10T for several years now. Its Vicnyl semi-aromatic resin features better resistance to hydrolysis compared with PA 9T and PA 46 and employs a naturally-derived monomer.
PA 10T is based on decanediamine, a renewable raw material derived from castor beans, and terephthalic acid. The bio-based carbon content in Vicnyl ranges between 40%-60% by weight. The polymer is produced at a 2000-tonnes/yr plant.
Vicnyl PA10T has the lowest water absorption among commercialized semi-aromatic polyamides according to supplier Kingfa.
According to the supplier, Vicnyl materials are suited for a wide range of applications in the electrical and electronics, automotive, and metal-replacement fields. Two grades are currently available: Vicnyl650 glass-fiber reinforced PA 10T (50% glass fiber content) with heat-deflection temperature under load (HDTUL; ISO 75-2) of 280°C, water absorption (ISO 62) of 0.15% (23°C/24 hours immersion in water), and a Ul 94 HB rating at 0.4-3 mm thickness; and Vicnyl630 with HDTUL of 240°C, water absorption of 0.6% and UL 94 rating of HB. —[email protected]
