Polyphthalamide high-performance polyamide

High- performance polyamide Polyphthalamide HPPA/PPA/ HTN Amodel, Kalix... 

After 1980 continuous growth was recorded with the development of a number of high performance polymers that could compete with traditional materials such as polyetheretherketone, polyetherimide (1982), polyamide 4,6 (1987), syndiotactic PS (1989), metallocene polyolefins, polyphthalamide (1991), styrene-ethylene copolymer, syndiotactic PP in 1992 and nanocomposites [15]. 

Engineering and high performance plastics markets are characterised by a high degree of concentration. The top three world suppliers of polycarbonate (GE Plastics, Bayer and Teijin), for example, control around 70% of total supply. The three leading polyamide suppliers control 55% of world supply and the largest three ABS producers account for 57% of world production. The most extreme cases are polyetherimide, polyphthalamide and PSU, where there are only one or two world suppliers of each t5 e of plastic. 

Solvay Advanced Polymers offers the broadest range of high performance materials of any supplier. These include PPS, PSU/PES, LCP, polyketones, polyarylamide, polyamide-imide and polyphthalamide. The company, which is headquartered in the USA, was established in 2001 following Solvay s acquisition of BP s advanced polymers business.
