LGF 9621 is a polypropylene homopolymer reinforced with 60% by weight of long glass fibers. (PP-LGF60, Long Glass fiber Granulate).. This PP-LGF60 is a ‘concentrate' which has to de diluted with either 'neat'-polypropylene and/or mineral filled PP based compounds. The 'dilution' is typically done as a dry blend of granulates by means of gravimetric dosing devices at the injection-molding machine. A weight ratio of 1 : 2 of LGF 9621.00 and i.e. LGF 8100 PP-copolymer will result in a composite-system having 20% by weight of glass fibers. LGF 9621 has been especially formulated to meet the long term heat ageing resistance (LTHA) required for use in some automotive 'interior' applications i.e. instrument panel carrier or integrated door-modules. LTHA> 1000 h @140°C and/or LTHA > 400 h @150°C will be achieved after dilution to 20% GF-content with ‘neat'-PP (LGF 8000 or LGF 8100). The 'long' glass fibers (11 mm length) provide high stiffness, strength and impact-resistance of the injection molded parts. The properties shown below have been measured on standardized ‘dog bone'-shape specimens (ISO 3167). Note: The mechanical properties which will be present in 'real' injection-molded parts may be different - depending on the fiber-orientation and the fiber-length distribution profile - which themselves are resulting from hardware configuration and processing parameters (such as i.e. the type of screw and mixing elements, diameter and radii of nozzle and hot-runners, number and size of gates, injection speed during mold filling and backpressure during dosing cycle).
