Ludwigshafen, Germany - BASF has developed a nanostructured polyurethane foam to be used as insulation in its concept car collaboration with Daimler.
The Smart Forvision is an energy-efficient electric vehicle with a focus on temperature management and lightweight design, BASF said in a 1 Sept news release. The car was showcased for the first time at the 64th International Motor Show in Frankfurt in September.
BASF and Daimler worked together to bring "innovative technologies" from the chemical industry to the development of automotive energy-efficiency, according to BASF's release. This included the creation of a new high-performance polyurethane insulation material.
A BASF spokesperson told UTI 10 Oct that the key component of the insulating material is a vacuum-insulated high-performance foam, a cellular material with "pore sizes in the nanometre range." The polyurethane foam is produced and encased in a barrier film. The gas within the cells is then removed, creating a vacuum within the foam.
This gives an efficient insulating material with a lambda value of five, according to BASF, despite being only 1 cm thick. The spokesperson noted that it has lasting performance as the matrix material keeps the vacuum almost constant through the product's service life.
The foam is currently in pilot stage and not part of BASF's portfolio. However, it will be marketed after the completion of the pilot stage, the spokesperson said.
