Grivory® HTM-4H1

Grivory® HTM-4H1 is a polyphthalamide (PPA) grade reinforced with 40% mineral fiber. Is based on a semi-crystalline, partially aromatic co-polyamide. Shows almost isotropic properties and outstanding strength when compared to other mineral filled materials. Exhibits good dimensional stability, low warpage, good surface quality, UV resistance and heat resistance. Provides parts which are stiffer, stronger and have better heat distortion stability and chemical resistance at high temperatures. Is suitable for processing by injection molding. Used in automotive applications like fuel systems, powertrain & chassis, interior & exterior, in housewares & consumer goods like hydraulics & pneumatics, electrical & electronic, power transmission, sports & leisure and engineering tools. Complies with REACH, RoHS and WEEE.
