Scratch resistance for car interior applications

The amount of plastics in a car increases from year to year. This general trend is driven both by cost reasons and by the aim to reduce the weight of a car which results in lower fuel consumption. For example a today's standard car is made by 15% out of plastic materials. 20 years ago the amount was half of it.

In interior applications such as trims or panels often pp/talc is used, high glossy panels for the decoration of middle consoles are made of PMMA or PC/ABS. All these materials are sensitive to scratches. Each scratch destroys the high value perception of a car interior why the surfaces needs to be protected against scratches. We offer TEGOMER^® antiscratch additives that can be used directly in the compound for all standard polymer which are used for car interior & exterior applications.

The video clips show:

1. the test methods which we use to determine the scratch resistance of different polymers and surface types.
2. our technical expert Kathrin Lehmann in an interview sharing her insights, major findings and results of a BMBF supported project called “NaNoScratch”. Aim of the project was to explore the use of nano-particles in polymers to improve the mechanical properties.
