High performance polymers play a key part in the design and functionality of a car’s exterior components, such as doors and sills, lighting, roof systems, mud guards, front and rear bumpers, spoilers, hoods and wing mirror housing. These polymers must have the demanding mechanical properties of dimensionally stability, high toughness, stiffness and flexibility, good weathering and chemical resistance.

High-performance masterbatches are also required for the coloring of bumpers, exterior trim and roof boxes that are made of polyamide, polypropylene or plastics such as PC or PBT. Our range of color and black masterbatches have been specifically designed to offer the ideal mix of properties to ensure that your products meet these high demands.


Superior mechanical properties

Regardless of the polymer being used, our compounds and masterbatches can be formulated to provide the optimal balance of mechanical properties, including tensile strength, flexural strength, impact, hardness, creep resistance, heat deflection temperature, hysteresis and thermal mechanical performance, to give you the widest choice of materials suitable for your application.

Color Accuracy

As one of the preferred providers of tier-1 producers worldwide, we produce masterbatches for all the large automotive brands. Our colors are used in interiors, exteriors and electrical parts. With more than 500 running OEM colors and a deep understanding and extensive experience of the specific requirements of the automotive industry, we are not only a valued partner, but one of the market leaders in this field. In fact, 50% of cars manufactured around the world today use Tosaf red masterbatch in their seat belt push button.


For ultimate consumer appeal, a vehicle should feel as good as it looks. We have formulated solutions to create a pleasant tactile feel to exterior polymer surfaces.

Our Products

Light fastness

Light fastness additives prevent exterior car parts from fading over time due to UV radiation. Our products are specifically developed to give a high level of permanence, as measured by the Blue Wool Scale (BWS).

Weather fastness

Weather fastness protects colorants used in exterior car parts from degradation due to chemical pollutants. Our colorants have the highest Grayscale performance, for minimal fading over time.

High UV

Polymers are susceptible to photo-oxidation which over time causes the deterioration of mechanical properties and surface appearance. We produce a range of masterbatches that eliminate or vastly reduce the effects of UV radiation and photo-oxidation.
