Description
technical field [0001] The present invention relates to novel (extruded) polypropylene compositions suitable for use as automotive interiors and their use. Background technique [0002] Polypropylene was chosen as the material for automotive interior items because, in general, it is resistant to many environmental influences. However, such materials for automotive interiors must have a certain UV stability, long-term heat resistance and scratch resistance, which cannot be achieved by pure polymer materials such as polypropylene by themselves. Therefore, in order to meet this requirement, the polymers used must be mixed with different additives. Over the past few years, the standard requirements for UV stability, long-term heat resistance and scratch resistance have been increasing. Consequently, the amount of additives has also been increased to meet the higher demands in the automotive industry. However, as additives are added to improve, for example, scratch resistance ...
