According to Evonik, the new reinforcement capabilities of the basic polyphthalamides take into account many highly demanding automotive applications, with coal, mineral, glass fibre, and mineral fibre reinforcements able to be used to create virtually any combination of properties.
The polycondensation of hexamethylene diamine and a mixture of terephthalic and isophthalic acid (T:I = 7:3) to the polyphthalamide PA6T6I (poly[imino-(l,4-co-l, 3-dioxophenylene)-iminohexamethylenel]) was studied.
LONDON, July 21, 2015 PRNewswire/ -- With the heat resistant and low moisture absorption properties, polyphthalamide is popularly recognized as high performance polyamide and is ideal for use in a chemical environment or temperature extreme conditions.
Specialty glass products and more traditional E-glass are holding off competition from carbon fiber through new chemistry and optimization to meet the demands for higher-performance thermoplastics (like polyphenylene sulfide, long-fiber thermoplastics, liquid crystal polymer, polyphthalamide, and polyetheretherketone) that are starting to be developed.
Included is the 3000 series, based on an entirely new molecule and said to be the industry's first biobased amorphous polyphthalamide (PPA).
Solvay Specialty Polymers, a supplier of high-performance thermoplastics for the automotive industry, is offering the market its Amodel polyphthalamide (PPA) and Ixef polyarylamide (PARA) for key fuel line connectors and glycol connectors, which were previously moulded of nylon 12 resin.
Wetted materials for flow transmitters include ETFE and EPDM, ASTM-PPA, Polyphthalamide, and ISO-PA6T/6I, Grivory 40% GF.
This work deals with the amidation of PET at high temperatures to the polyphthalamide PA6T (poly [iminoterephtaloyliminohexane-1,6-diyl]) and derivatives thereof by diamines DA (Scheme 1).
Thermoplastics used for the adhesive evaluation were commercial test pieces of polycarbonate (PC), polybutyleneterephthalate (PBT), polyphenylene oxide (PPO), 6,6-nylon (PA66), 6-nylon (PA6) and polyphthalamide (PPA): commercial test pieces of metals were made of chromium-galvanized iron, stainless steel (SUS) and aluminum (A1).
In developing the impellers for these pumps, we considered resins such as polyphthalamide and several nylon derivatives, but these did not perform as well as PPS.
The report "Polyphthalamide Market by Type (Unfilled, Mineral Filled, Glass Fiber Filled, & Carbon Fiber Filled), by Application (Automotive, Electronics 7 Electricals, Industrial Equipment & Apparatus, Consumer & Personal Care, & Others) - Global Trends & Forecast to 2019", defines and segments the global Polyphthalamide Market with analysis and forecast in terms of volume.
com) reportedly fills the gap between nylon 6 and polyphthalamide (PPA).
