Right: Grivory HT1 is a new PPA from


EMS-Grivory for high heat applications


either 40 or 50% glass fibre reinforcement and the choice of organic or inorganic stabilisers. Potential target applications include automotive clutch and gear components as well as structural parts and supporting brackets in the engine compartment. The company also introduced Grivory G5V, which


offers a modulus of elasticity in the conditioned state at 80°C around 40% higher than that of the existing Grivory GV product and reduced water uptake. Two 50% glass reinforced grades are offered with focus applications including automotive interior parts requiring tempera- ture resistance at up to 80 or 100°C. Also new is Grivory G6VX-AP (Advanced Perfor-


mance), described as a new generation of high-perfor- mance polyamides for high precision components. The products are said to be characterised by very high stiffness and impact strength as well as high dimen- sional stability. Target applications include thin-walled structural frames for portable electronics. ❙ www.emsgrivory.com


Spain’s GCR Group said that the expansion programme it initiated in the summer is on track and will be completed by the end of the year, lifting its annual production capacity for mineral filled masterbatches from 220,000 to 300,000 tonnes. The company also presented the results of some of


its latest development projects, including a develop- ment with film producer Kivo and converter CMD that has resulted in a 19% reduction in Global Warming Potential in refuse sack production. Incorporation of


20% of its Granic 1522 CaCO3 masterbatch, which is based on Vistamaxx resins from ExxonMobil, in a monolayer HDPE refuse sack film allowed Kivo to downgauge from 18 to 15 microns, saving material and processing energy. Aside from the environmental gains, the company claims that the addition of Granic 1522 to an existing HDPE resin formulation allows thinner film structures to be used while enhancing dart impact strength. ❙ www.gcrgroup.es


Composite technology – both continuous fibre reinforced thermoplastic hybrids and short glass fibre reinforced compounds – features heavily in the Lanxess display with two transportation applications standing


Right: A hybrid thermoplastic composite brake pedal produced for Porsche using Lanxess materials


76 COMPOUNDING WORLD | December 2016


out: an award winning brake pedal for the Porsche Panamera and a new air filter support system for Daim- ler trucks. Developed by BOGE Elastmetall and used on the


Panamera and the Bentley Continental cars, the brake pedal was a winner of the Body Interior category in the SPE Automotive Awards. Comprised of a Tepex multi-axial continuous fibre reinforced thermoplastic composite sheet overmoulded with Durethan BKV 60 H2.0 60% glass reinforced PA6, the part weighs half that of a steel counterpart. The part is manufactured using a one shot hybrid moulding process that integrates the shaping of the Tepex insert. “Thanks to the injection moulding process, numerous functions such as guides and contact surfaces for the pedal bracket can be integrated into the component, which cuts costs. The component is also reinforced with ribs in areas subjected to high stress,” said Ulrich Jecmeniza, an expert in lightweight construction with Lanxess subsidiary Bond-Laminates, manufacturer of the Tepex sheet. The company also showed a new air filter carrier


developed by BBP Kunststoffwerk Marbach Baier for Daimler Trucks and injection moulded in 50% glass reinforced Durethan AKV 50 H2.0 PA66. The parts, which have to support a load of 7.9kg, weigh half as much as the previous metal alternatives at just 2.9kg and required the use of a complex tool with optimised cooling. “The numerous cores in the mould required a complex, contoured design of the cooling system,” explains Horst Hauke, President of BBP. ❙ www.lanxess.com


Merck introduced its Thermaval range of high tempera- ture pearlescent pigments, which offer thermal stability at up to 1,100 °C. Primarily developed for applications in the ceramics sector, the company said its sees applications for the new pigments in high performance plastics exposed to extended use periods at elevated temperatures. Four temperature-stable effect pigments area available in the Thermaval series:
