Scratch resistance for car interior applications

Plastic Additives

Our competencies in the automotive sector.

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:
  • the test methods which we use to determine the scratch resistance of different polymers and surface types.

  • 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.  

Product Listing

  • TEGOMER® AntiScratch 100

    TEGOMER® Antiscratch 100 significantly increases the scratch resistance of plastic compounds (pp/talc) used for car interior applications like door panels or center console trims. In contrast to standard additives TEGOMER® AntiScratch 100 guarantees a durable and long lasting effect. Moreover, TEGOMER® AntiScratch 100 is a non-migrating additive which does not cause fogging, it has no influence on the haptics of the surface and the additive is absolutely odorless.
