Creative innovation from lightweight solutions to surface aesthetics

Sustainability plays an increasingly significant role in automotive manufacturing. Key drivers of sustainability in the industry include lightweight solutions: both the replacement of metal parts with energy efficient and lighter weight plastics as well as down gauging lead to improved fuel economy and lower CO2 emissions. Replacement solutions, however, must offer comparable or even superior mechanical performance, and must fulfil the most sophisticated aesthetic, haptic and even olfactory demands of today's end users.

Optimised performance and surface aesthetics

Borealis offers a comprehensive range of innovative polypropylene (PP) and thermoplastic polyolefin (TPO) solutions for automotive applications such as dashboards, door panels, centre consoles, trims, structural components and more. Our PP and TPO polymers and compounds have properties that are balanced and tailored to precisely match all your application needs. They deliver surfaces exhibiting:

  • Non-stickiness
  • Low gloss
  • High scratch resistance
  • Absence of flow marks (e.g. so-called "tiger stripes")
  • Good haptics (pleasant to the touch)
  • Odour-neutrality
Based on our proprietary Borstar® technology, our materials solutions:
  • Comply with the most stringent purity criteria, even in high melt flow rate (MFR) ranges
  • Offer a very broad processing window
  • Add value by helping to lower system costs while providing reliable performance to the highest global industry standards
  • Enable faster development-to-production cycles
  • Reduce both material and energy inputs for enhanced sustainability

Fibremod™ for lightweight and robust solutions

For applications requiring an optimal stiffness/toughness balance, our Fibremod™ family of engineered short (SGF) and long glass fibre (LGF) compounds is the optimal solution. Their strength and durability makes them the ideal replacement for metals and engineered plastics, thus enabling significant vehicle weight savings and greater fuel economy without any compromises in mechanical properties. Moreover, they give reliable, corrosion-free performance throughout a vehicle's lifespan.

Creative innovation for the automotive industry

Building on our unique Borstar® technology and more than 50 years experience in polyolefins, Borealis provides innovative, value-creating plastics solutions for the automotive industry. In the spirit of creative innovation, we are dedicated to developing material solutions which meet both the existing and the projected needs of the industries we serve, working with partners to identify needs before they become challenges and developing solutions that add value along the supply and production chain through to and including the end user. Our newly-developed low density grades for visible and structural parts support the industry's efforts to reduce the weight of vehicles in the interests of sustainability.

Fibremod™

Engineered for success

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).

Consolidated strengths of Fibremod

In order to help our customers and partners identify, compare and select the right grade for their own needs, Borealis and Borouge have consolidated all its fibre reinforced PP material grades under the single name Fibremod. For the most part, Fibremod materials are designed for the higher performance demands of automotive and appliance applications. They provide the complete spectrum of mechanical and chemical resistant property combinations to offer the widest range of solution possibilities. This delivers time and cost savings through greater processing efficiency, parts integration and end-use performance, as well as reductions in part application weight as well as energy and material consumption.

Fibremod benefits at a glance

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.

  • Broad portfolio, from 10%-40% filled standard grades to tailor-made products with optimised matrices, glass fibres and/or filler mixture contents for the most demanding of applications
  • Global availability and production flexibility
  • Wide range of achievable performance attributes thanks to flexibility in selection of base polymers
  • Wide conversion window
  • Less sensitive to welding line, enabling greater design freedom
  • Good surface properties
  • Good organoleptic properties

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.

  • Broad range of fibre and matrix combinations covering glass fibre contents from 20%-60%
  • Highest stiffness and strength at elevated temperatures thanks to tailor-made solutions
  • Proprietary technology enables high fibre impregnation
  • Excellent flowability for smooth processing and uniform shrinkage behaviour
  • Outstanding energy absorption in high-speed deformation
  • Ideal for applications requiring increased impact, temperature and fatigue resistance while maintaining high stiffness
  • Low shrinkage anisotropy (warping)

Reliable global partner in product innovation

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.
