Q1: What are the key performance advantages of Novoperm Orange HL 70 in high-temperature polymer applications?
A: Novoperm Orange HL 70 offers excellent thermal stability and resistance to pigment degradation during melt processing of engineering plastics such as polypropylene, polyethylene, and polyesters. Its robust molecular structure supports good color retention and minimal blooming or plate-out under demanding extrusion and injection molding conditions.
Q2: Is this pigment suitable for use in food-contact plastic packaging?
A: Novoperm Orange HL 70 is designed for general industrial and non-food-contact applications. For food-contact compliance, specific regulatory approval depends on the final formulation, polymer matrix, and regional requirements—users must conduct full regulatory assessment and obtain appropriate documentation from Clariant prior to use in food-contact articles.
Q3: How does Novoperm Orange HL 70 compare to conventional azo orange pigments in terms of lightfastness and weather resistance?
A: As a high-performance perylene-based orange pigment, Novoperm Orange HL 70 delivers significantly improved lightfastness and weather resistance compared to standard mono-azo or disazo orange pigments. It maintains strong chroma and hue stability under prolonged UV exposure, making it well-suited for outdoor applications and durable masterbatches.
Q4: What dispersion methods are recommended to achieve optimal color development and consistency?
A: Optimal dispersion is typically achieved using high-shear compounding techniques—such as twin-screw extrusion—with compatible carrier resins. Pre-dispersed masterbatches are widely used to ensure uniform distribution. Avoid excessive shear or extended residence time at elevated temperatures to preserve pigment integrity and color strength.
Q5: Can Novoperm Orange HL 70 be combined with other high-performance pigments in multi-pigment systems?
A: Yes, Novoperm Orange HL 70 demonstrates good compatibility with other high-stability organic pigments—including quinacridones, perylenes, and diketopyrrolopyrroles—in both dry blends and co-compounded systems. Compatibility testing is recommended to confirm absence of adverse interactions such as flocculation or hue shift in the target polymer system.
