Scratch Resistance



Appearance is a key aspect of perceived quality in car interior. Plastic parts made of polypropylene are more prone to mar and scratches which create an impression of lower quality. Additionally, dust and dirt tend to find their way into the rough surface accounting for a less hygienic environment and a reduction of the mechanical properties. The use of anti-scratch additives help to preserve the perceived quality of the surface and its mechanical properties. 

Clariant offers a selection of anti-scratch additives for automotive and consumer goods applications under the name CESA®-scratch. The selection of the additive packages depends on different parameters such as process, application, resin grade, color, presence of fillers, as well as the standards to be fulfilled. Our CESA®-scratch additives have no negative influence on surface migration or VOC emissions and can be supplied as well in color version, to match OEM color targets and anti-scratch effect in one single masterbatch solution.

  • Color Masterbatches

    Clariant brings dramatic color to plastic resins and all applications. Color that delights the eye. Color that differentiates. Color that adds value. Color that identifies form and function. Clariant products include REMAFIN® masterbatches for polyolefin polymers, RENOL® masterbatches for high-performance engineering thermoplastics, OMNICOLOR® multipurpose color concentrates, and MEVOPUR® medical-grade masterbatches for the medical industry, delivering hundreds of standard colors as well as custom formulations and color/additive combibatches. From business machines and appliances to textiles, automotive components and packaging, designers, brand managers and plastics processors rely on cutting-edge color technology and in-depth technical support through more than 50 global manufacturing sites and regional offices. more

  • Black & White Masterbatches

    Producing the purest whites and the deepest blacks for plastics can pose special challenges. These special masterbatches require high pigment concentrations and must be carefully formulated to ensure compatibility with the polymer matrix and uniform color development in the finished product. Contamination cannot be tolerated. Clariant Masterbatches has vast knowledge and experience in making these special colors and, in many cases, has dedicated entire processing plants to producing them. Strategically located around the world, these facilities are your assurance of fast delivery and the highest levels of local service. more

  • Additive Masterbatches

    CESA® additive masterbatches from Clariant offer remarkable opportunities to improve the performance of plastic products. They can prevent degradation due to heat and shear during processing as well as UV light and oxidation in the end-use environment. They can limit flammability to comply with key regulations and they can reduce product weight and resin consumption, prevent the build-up of static electricity, or make plastic surfaces easier to print or laser etch. Available in pellet, granule or liquid form, as single-function masterbatches or custom-made combibatches, CESA additive masterbatches are also easy to handle and easy to store. Very recently, many functionalities were also developed as masterbatches for the medical and pharmaceutical industry under the MEVOPUR® brand. more

  • Liquid Masterbatches

    A liquid masterbatch is a custom blend of additives and pigments dispersed in a liquid vehicle chosen in order to ensure compatibility with the end-use polymer. The decision to use liquids should be based on the specific requirements of the application and Clariant can provide excellent guidance when it comes to making the choice. Due to liquid masterbatches easy incorporation into the polymer matrix they are an excellent choice when it comes to transparent or translucent colors, parts with large wall thicknesses and customers who's operations experience multiple color changes per shift. Because liquid Masterbatches are not compounded at high temperatures and pressures, they represent a good option when heat-sensitive pigments or additives are required. Liquids can be metered with Clariant's very precise state-of-the-art dosing systems with wireless control for recipe control and inventory management. Liquid masterbatches can be formulated to improve the flow properties of the polymer, with fast filling times and shortened injection molding cycles, as well as improved extrusion throughput and low screw speeds. more
