- Polyphthalamide abstract "Polyphthalamide (aka. PPA, High Performance Polyamide) is a diverse subset of thermoplastic synthetic resins in the polyamide (nylon) family defined as when 60% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids. Some of them have been used to replace metals in high temperature automotive applications, as the housing for high temperature electrical connectors and multiple other uses. PPAs are polyamides containing aromatic rings in the diacid part of their backbones, which gives them high mechanical strength and thermal resistance.As a member of the nylon family, it is a semi-crystalline or amorphous material composed from a diacid and a diamine which means PPA is formed by the reaction of aromatic acids with aliphatic diamines. However, the diacid portion contains at least 55% terephthalic acid (TPA) or isophthalic acid (IPA). TPA or IPA are aromatic components which serve to raise the melting point, glass transition temperature and generally improve chemical resistance vs. standard aliphatic nylon polymers and reduce water absorption. If more than 55% of the acid part of a PPA is made out of IPA, then the copolymer is amorphous.Polyphthalamide with 6T-SegmentPolyphthalamide with 6T-SegmentPolyphthalamide with DT-SegmentPolyphthalamide with DT-SegmentIn recent years, polyphthalamides have been commercialized by several polymer resin manufacturers which are under the trade names Amodel, Grivory, Ultramid T, VESTAMID HTplus, Akromid T and Zytel HTN.".
