Q1: What is the primary chemical composition of VANADUR 9010?
A: VANADUR 9010 is a high-performance inorganic pigment based on a mixed metal oxide system, engineered to deliver stable yellow-to-orange hues with excellent thermal and chemical resistance. Its exact phase composition is proprietary to Heubach, but it is formulated without heavy metals such as lead, cadmium, or mercury.
Q2: Is VANADUR 9010 suitable for use in plastics processing at elevated temperatures?
A: Yes — VANADUR 9010 is specifically developed for demanding polymer applications, including injection molding and extrusion. It demonstrates outstanding thermal stability up to typical processing temperatures of polyolefins, engineering thermoplastics, and certain thermosets, with minimal color shift or degradation under standard residence times.
Q3: How does VANADUR 9010 perform in terms of lightfastness and weather resistance?
A: As an inorganic pigment, VANADUR 9010 offers inherently high lightfastness and excellent resistance to UV exposure and atmospheric conditions. It is widely selected for outdoor applications where long-term color retention is critical, such as automotive exterior components and architectural plastic profiles.
Q4: Can VANADUR 9010 be used in food-contact plastics?
A: VANADUR 9010 is designed to meet stringent regulatory expectations for indirect food contact applications. While final compliance depends on the full formulation and end-use conditions, the pigment itself contains no intentionally added substances restricted under major global food-contact frameworks, and is routinely evaluated by customers for use in approved packaging and processing equipment.
Q5: What is the recommended dosage range for optimal color development and dispersion?
A: Dosage depends on the base polymer, desired shade intensity, and processing method. VANADUR 9010 is typically used at low concentrations due to its high tinting strength and opacity — generally ranging from 0.1% to 2% by weight — with effective dispersion achievable using standard compounding equipment and appropriate carrier resins.
