The interior of a car, whether in terms of comfort or added luxury, plays a vital role in the consumer’s decision to make a purchase. Trims, steering components, the instrument and door panel, headliner, safety systems and pedals, load floor, seating and composites, all play a part in creating the right esthetic. They can even affect performance, safety, cost and longevity of the vehicle.

When it comes to both functionality and color of the polymers used in this application, Tosaf is the partner of choice of many OEM, tier one, two and three suppliers.


Low VOC Emissions

Exposure to air pollutants has for many years been recognized as major cause of health problems. Emissions of volatile and semi-volatile organic compounds from car interiors can have an adverse effect on vehicle interior air quality (VIAQ), raising concerns for passenger health and safety. We select our additives, colors and base polymers carefully to ensure that they are suitable for use in car trim components and meet the limit levels specified by various automobile associations.

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.


Consumers want to drive a vehicle that feels as good as it looks. Our soft-touch solutions give polymer surfaces a warmer, more pleasant tactile feel.

Superior mechanical properties

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

Our Products

Light fastness

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

High UV

Polymers are susceptible to photo-oxidation that results in the deterioration of mechanical properties and surface appearance over time. Our range of masterbatches eliminate or vastly reduce the effects of UV radiation and photo-oxidation.

Scratch and Mar Resistance

Scratch and mar resistance of automotive plastics is becoming increasingly importantת due to the trend to eliminate paint in favor of molded-in color. Our anti-scratch masterbatch reduces the whiteness that makes scratches and scuffs visible, particularly in black and high vibrancy shades.

Fire Resistance

Materials used in the passenger compartment of vehicles needs to have a high degree of burn resistance so that occupants have time to escape the vehicle in the event of a fire. We offer a range of formulations that help to achieve resistance to fire and a safe reaction to fire.

Thermal management

Surfaces can become very hot under solar irradiation, impacting energy consumption used for cooling, and affecting the durability and integrity of the material. Our range of polymer masterbatches control the thermal load of black and other color surfaces.

Conventional materials used in car interiors tend to attract dust. Our range of e-tech permanent anti-static compounds repels dust to maintain a factory-fresh appearance in automotive interiors over years of use.

Laser marking

We offer a number of technical solutions to enhance the effect of the laser to either improve charring, create a dark mark, or improve foaming to create a light/white mark. Our masterbatches have all been proven and our colorants are selected to enhance the marking effect.
