WebThe permeability and solubility of gases and liquids in a polymer can be very different for different polymers and permeants. In general, permeability and solubility at a given temperature depend on the degree of crystallinity (morphology), the molecular weight, the type of permeant and its concentration or pressure, and in the case of copolymers, also … WebSep 12, 2024 · 4.5: Crystallinity in Polymers. We often think of polymers in the form of plastics: solid materials that serve some structural function, like a water bottle or some Venetian blinds. Polymers are different from many other such solids. Metals, for instance, have crystalline structures, in which atoms form a regularly repeating pattern, row upon … lewis formula nh3
Polyphthalamide (PPA) RTP Company
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 … 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. … See more Polyphthalamide based resins are injection moulded into parts that are used in a wide variety of applications. Automotive uses include fuel and coolant lines, pump wear rings, motor bobbin parts, fuel line connectors, water heater manifolds fuel … See more • Arkema under the brand Rilsan HT polymers based on decanediamine, presumably 10T/X. • BASF under the brand Ultramid Advanced N (PA9T), Ultramid Advanced T1000 (PA6T/6I), Ultramid Advanced T2000 (PA6T/66), Ultramid T KR (PA6T/6).
