Exterior

For exteriors that don’t just look good

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 robust mechanical properties of dimensional stability, toughness, stiffness and flexibility, good weathering and chemical resistance. In terms of color too, high-performance masterbatches are required for bumpers, exterior trim and roof boxes made of polyamide, polypropylene or plastics such as PC or PBT. Our range of color and black masterbatches has been specifically designed to offer the ideal mix of properties to meet these 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

Color accuracy is critical to avoid mismatched colors across the exterior of the car. The extensive expertise of our colorists, together with our state-of-the-art spectrophotometers, allow us to meet the most stringent tolerance demands operating within the industry

Tactile properties

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

Our Solutions

LF

Light Fastness

Specifically developed to deliver a high level of color permanence, Tosaf’s light fastness additive prevents colors from fading over time, ensuring a high rating on the Blue Wool Scale (BWS).

Highlights

  • Prevents fading over time

  • Prevents fading over time

  • High Blue Wool Scale (BWS) rating

UV

UV Light Stabilizer Masterbatch

Long-term exposure to UV radiation compromises the integrity of plastic, making it brittle and prone to cracking or breaking. The masterbatches in Tosaf’s UV light stabilizer range eliminate or vastly reduce the effects of UV radiation and photo-oxidation, offering long-term polymer protection.

Highlights

  • Prevents premature polymer degrading and failure

  • Minimizes deterioration of mechanical properties

  • Extends high-quality surface appearance

WF

Weather Fastness

Protect plastics from year-round weather conditions. Tosaf’s high-performance weather fastness masterbatch protects colorants from degradation and fading over time, offering the highest grayscale performance.

Highlights

  • Highest grayscale performance, for minimal fading over time.

  • Impacts dimensional stability

  • Transparent

CM
