Innovation Award “Bio-based Material of the Year 2015” goes to Bayer MaterialScience AG for the firstbio-based polyurethane crosslinker for high performance automotive coatings

The competition focuses on innovative materials and products, which have had (or will have) a market launch in 2014 or 2015

German version:

For the eighth year running the Innovation Award “Bio-based Material of the Year” is awarded to the young, innovative bio-based material industry, finding suitable applications and markets for bio-based products. The competition focuses on innovative materials and products, which have had (or will have) a market launch in 2014 or 2015. The prize has been awarded by nova-Institute and sponsored by Coperion GmbH, one of the leading compounding and extrusion companies, at the “8th International Conference on Bio-based Materials” in Cologne (Germany), 13 April 2015. With 220 participants from more than 20 countries, it is one of the biggest conferences in the world, gathering the latest developments in the field of bio-based materials and providing an excellent platform for networking. 

Six bio-based materials and products have been nominated for the Award by the advisory board – out of 24 submitted products. The nominated companies were from the United Kingdom, the United States and Germany. In a 10-minute presentation, each nominated company explained their innovative materials and products to the audience. The three winners were elected by the participants of the conference and awarded with the prize at the dinner buffet. The winners of the Innovation Award “Bio-based Material of the Year 2015” are:

1) Bayer MaterialScience AG (Germany): DESMODUR® eco N – First bio-based polyurethane crosslinker in the market for high performance automotive coatings: Polyisocyanate based on Pentamethylene Diisocyanate (PDI)

The limiting factor for bio-based polyurethanes has been the need for polyurethane crosslinkers based on renewable feedstock, since bio-based polyols solutions already exist. Bayer MaterialScience has taken up this challenge and developed DESMODUR® eco N: a new solvent-free aliphatic polyisocyanate and the first polyurethane crosslinker on the market with a significant renewable content that has not come at the expense of performance. This crosslinker is based on a new isocyanate, pentamethylene diisocyanate (PDI), 70 percent of whose carbon content comes from biomass. Furthermore it is produced using energy-efficient gas-phase technology, to assure minimum impact on the carbon footprint. This product enables the production of bio-based polyurethanes for high-performance automotive coatings.


2) HIB TRIM PART SOLUTIONS GmbH (Germany): Nature 50 – Natural fibre reinforced plastic (Hemp – PP) including a long fibre ratio > 50% for injection moulding

In the last years, many companies have developed natural fibre reinforced PP granulates – but the market success has been limited. Our new Nature 50 granulate is a completely new development with unique properties. Long hemp fibres (> 50%) are mixed with PP and additives in an innovative cold-press technology (no extruder). The granulate can then be extruded and injection moulded in serial moulding tools. The long hemp fibres give a unique design and a good Charpy impact property to the material – making it suitable for automotive parts. The weight reduction is between 18 and 20% in substitution of serial plastic PC ABS GF20. Also impact strength, shrinkage and heat expansion show attractive properties.

As a pure injection moulding part, Nature 50 shows an extraordinary appearance due to the long fibres, which can be varied through colouring. Therefore the material offers a wide range of design options in- and outside of the automotive sector.


3) EcoTechnilin Ltd (UK): FibriRock innovative composite material for aircraft applications comprising flax non-woven, basalt yarns and a sugar-based bioresin. Co-developed with TFC

FibriRock: a lightweight bio-sourced fast-curing composite with excellent FST performance. Certified for use in an airline galley cart, FibriRock combines a Nomex-type core with skins formed from flax, basalt and a sugar-based bioresin. There are three reasons why FibriRock is so special in the field of aerospace composites: the skins, which represent 87% of the material, are 100% biosourced; the fast processing times (150 seconds) are pretty exceptional in the field of aircraft composites where most sandwich-type materials take between 40 and 70 minutes to cure; and the low heat release rate figures (15 kWmin/m2) are three times lower than competitive materials enabling clients to use much cheaper films and decorative finishes. Hence FibriRock is taking EcoTechnilin to new heights!
