Improved Lupranol Manufacturing Process

Lower Emissions in Car Interiors

According to the manufacturer, the improved manufacturing process of Lupranol makes an average reduction in aldehyde emissions of 20 % possible (© BASF)

BASF has now improved the process for manufacturing Lupranol (polyether polyol) so that car components which are made of BASF polyurethane systems emit an average of 20 % less aldehyde. This allows automotive suppliers, that manufacture e.g. acoustic parts, seats and steering wheels or back-foam instrument panels and doors, to meet the increasing requirements of car manufacturers and the law for lower emissions (VOCs: Volatile Organic Compounds) in vehicle interiors.

Following the process change at BASF’s Asian production sites at the beginning of 2017, the modification is now being made in Europe and will take place in the US plants during the course of this year. Alongside isocyanate, polyol is the starting product for polyurethane foam systems.

The emissions have been optimized by improving the cleaning and finishing processes of Lupranol in such a way that the mechanical properties of the material remain unchanged during the following foam and processing steps. This means that the currently used Lupranol grades can be exchanged immediately, there is no need for elaborate tests or renewed approvals of the PU systems which are based on these improved polyol grades.

With the improved Lupranol grades BASF contributes to automotive components with ever lower emissions. Completed parts made of BASF PU systems are tested internally as well as by certified test laboratories like Imat-Uve and Institut Fresenius. The improvement of the emission values varies from part to part: An average reduction of 20 % is possible, measured according to commonly accepted chamber test methods like VDA276 and BMW GS 97014-3.
