Minimizing Emissions of automotive leather

Konferenzbeitrag

Content: Today, automotive leather has to meet a multitude of requirements for different automotive brands. In addition to the important traditional aesthetic properties, such as the feel and appearance of the leather, a growing number of measurable specification parameters have been added over time. One of these parameters are the Volatile Organic Compounds (VOC) which the final leather article emits. The large number of emission specifications, each with its own limits, represents a major challenge in the development of automotive leather today. Each of these methods has a slightly different substance focus and highlights certain groups of volatile substances in the test result. This often makes a targeted development for a certain leather article with associated test method necessary. The recurring question of how to further reduce the emissions of automotive leather is answered by presenting the latest developments from the Leverkusen laboratories as one focus of this work. The increasingly profound measurement of the emissions over the last decades has led to VOCs becoming reduced from grams to micrograms per kilogram of leather. Most probably because of this dramatic reduction in VOC levels, the focus of the regulations has switched today more from quantity of emissions to the properties of single substances emitted. Often the exact source of these substances were initially unknown and consequently a specific solution to meet the limits were not available. The search for the sources is becoming increasingly complex and difficult as many of these substances are not applied directly but are often degradation products of other compounds. Often the measured low concentrations are in the range of the natural decomposition processes. Nevertheless, it is possible to identify some of the sources by evaluating the results of different analytical methods. Thus it is now possible to develop suitable countermeasures. The presentation of the source of special single volatile organic substances as well as their reduction forms a further focus of this work.
