Your TFL solution for better air quality in car interiors
Emissions of volatile organic compounds from vehicle trim components such as leather can affect the interior air quality and therefore the comfort and health of drivers and passengers. Several countries have therefore established regulations and guidelines about vehicle interior air quality (VIAQ) and the automotive industry has specified chemical emission limits and testing requirements for automotive components.
Product selection to fulfill low emission specifications
Chemicals applied in the leather processing may cause unwanted VOC emission. Therefore a careful screening of all products used from beamhouse to finishing needs to be performed to understand the main sources of potential emissions.
Fatliquoring has a high impact on the emission behavior of leather – be it odour, fogging or harmful substances. Enjoy significantly reduced emissions in your car interior with an innovative TFL fatliquoring concept. Thanks to CORIPOL® LE / AV / AT you can enjoy a soft and smooth ride with the best in class emission behavior for automotive leathers of all kinds.
Chinese Emission GB / T27630
The chinese government is defining a new national standard specifying different concentration limits for eight VOC’s emitted by components used in car interiors. Acetaldehyde in automotive leathers is the biggest challenge within the eight VOC’s of GB / T27630. Acetaldehyde has a very low boiling point and is highly water soluble; nevertheless it may occur in leather and can be detected in emission tests, such as TSM0508G:2009 & TIS 01204-00351A.
How to control acetaldehyde in leather?
Acetaldehyde isn’t used in the synthesis of TFL products, however, small amounts may be found with extraction methods. Therefore TFL has selected products to be used from beamhouse to finishing which allow leather production with a significant reduction in acetaldehyde, such as:
RODA® Tec AI – the acetaldehyde Inhibitor
TFL has developed an acetaldehyde scavenger to be used in wet end applications and in finishing to eliminate remaining acetaldehyde which may still be present in spite of optimized product selection.
