Short-cut hemp is compounded with PP to make chips for injection mouldings. Their use provides:
· 25% weight savings.
· 20% LCA Savings (CO2).
· Processability on existing machinery with a 6% reduction in cycle time.
· A step on the road to 100% bio-composites.
It is more expensive than P/E copolymer but currently perceived as the best compromise between quality and weight. It is now used in the Peugeot 308. 3000 tonnes are produced in the EU and a further 10000 tpa planned for Asia.
Faurecia is also developing its own 100% bio-based polymer “Biomat”, for non-visible auto parts. Biomat is 100% poly-butylsuccinate made from tapioca starch using monomer technology from BioAmber and polycondensation technology from Mitsubishi Chemicals.
