Leverkusen, Germany – Covestro PU foam is being used in a composite with hibiscus fibre in light-weight door trims for the new Toyota LQ electric concept car.

The composites use Covestro's Baypreg F NF technology to make the door trims. These are 30% lighter than trims produced from conventional materials, said Covestro. The Baypreg base materials typically have flexural strength between 15-18 MPa at 22°C, it said.
'[The products are] a good example of using alternative raw materials,' said Hiroaki Ido, head of polyurethane development at Covestro's Japanese Innovation Center.
Kenaf, which is used in the composite, is part of the hibiscus family that is grown in South East Asia, Bangladesh, India and Africa. The composite was developed by Covestro and Toyota Boskoku, the part of Toyota that makes car components.
