Polyphthalamide (aka. PPA, High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide (nylon) family defined as when 55% 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 … See more The diamines in PPAs are aliphatic. PA6T homopolymer melts at 371 °C, which renders it intractable. To make usable polymers, it is necessary to lower the melting point, which can be achieved practically using … See more Compared to aliphatic polyamides, PPAs offer improved • chemical resistance • higher strength and stiffness at elevated temperatures See more PPAs, as any thermoplastic, are theoretically fully recyclable by remelting, and as a condensation polymer by depolymerization. Commercial recycling requires the cost of … See more Polyphthalamide based resins are injection moulded into parts that are used in a wide variety of applications.
