Polyphthalamide (aka PPA, Polyamide High Performance) bụ akụkụ nke thermoplastic synthetic resins na ezinụlọ polyamide (nylon) akọwapụtara dị ka mgbe 55% ma ọ bụ karịa mole nke akụkụ carboxylic acid nke akụkụ ugboro ugboro na polymer yinye bụ ngwakọta. Acids nke terephthalic (TPA) na isophthalic (IPA). Ngbanwe nke aliphatic na-ekpebi site na aromatic na-ekpebi na ọkpụkpụ azụ polymer na-abawanye ebe mgbaze, iko mgbanwe okpomọkụ, nguzogide kemịkalụ na isi ike.
