Fibre reinforced polypropylene for light, integrated, high performing solutions.
Global manufacturers of motor vehicles and appliances require new material solutions to replace existing conventional ones. Such materials must not only meet or exceed current performance and quality levels, but must also be globally available, cost and energy efficient, and help contribute to enhanced sustainability. Our Fibremod™ product family of fibre-based compound polypropylene (PP) innovations supports the automotive and appliance value chain in achieving weight-saving and process cost-saving targets. Replacing engineering plastics and metal parts with energy efficient and lighter weight PP grades leads to improved fuel economy and lower CO2 emissions. Our customised glass fibre reinforced PP solutions are at the cutting edge of innovation, bringing lighter weight, extra strength and impact performance to a wide range of applications. Our innovative grades also support more environmentally-considerate production by reducing processing temperatures and energy requirements when replacing alternative solutions such as polyamide (PA).
Short glass fibre reinforced polypropylene (PP-SGF) products are produced as compounds on co-rotating twin screw extruders. The combination of specially sized short glass fibres, the PP matrix and the chemical coupling define the final material properties. PP-SGF products are usually converted to parts using various injection moulding technologies, including complex processes such as injection compression moulding or injection foam moulding.
Long glass fibre reinforced polypropylene (PP-LGF) is a group of glass fibre reinforced products which are produced by pultrusion to achieve increased fibre length in both pellets and final parts. The glass fibres are typically arranged in a parallel manner in the pellets, with each having the same length as the pellet itself.
Borealis has extensive experience in developing balanced PP-SGF recipes to meet customer demands. We use the best production technology available for optimal product performance and to support customers in material conversion.
We have over 20 years experience in producing PP-LGF and have developed a proprietary processing technology which produces high-quality products in terms of fibre impregnation, and a broad range of fibre and matrix combinations for tailor-made solutions.
We offer our customers flexibility in production around the world: PP-SGF is produced at Borealis and Borouge plants in Monza (Italy), Beringen (Belgium), Itatiba (Brazil), Shanghai (China), and in North America via toll compounding. PP-LGF is produced both in Monza as well as by way of toll compounding.
Because glass fibre reinforced PP grades are by nature complex in structure, extensive engineering is required. Computer-aided methods reliably predict the final part qualities of the conversion processes (shrinkage, warping etc.), as well as the fibre orientation distribution. Based on these results, our Integrative Simulation Approach computes on a local scale the material behaviour as the basis for simulating performance of the final application. We have established the latest testing standards for glass fibre reinforced PP grades and are committed to further enhancing application performance prediction methodologies.
