GenestarTM PA9T is a special semi-aromatic (terephthalic acid) polyamide engineering plastics composed of C9 monomers, which was commercialized by Kuraray for the first time. This product is well applicable in numerous modifications such as fibres, films or resin. Based on this very different and versatile subsequent processing is possible. We introduce the superior performance of GenestarTM PA9T especially desired for very demanding applications and environments. More specific fibre reinforced composites such as UD tapes and organo sheets shall be described in detail. Different application areas are highlighted.
