Q1: What are the primary application areas for Clariant HR02 Organic Pigment?
A: Clariant HR02 is widely used in high-performance plastics applications, including polyolefins (PP, PE), engineering thermoplastics (e.g., ABS, PS), and masterbatch systems where excellent heat stability, lightfastness, and dispersion behavior are required.
Q2: How does HR02 perform under processing conditions typical for injection molding or extrusion?
A: HR02 exhibits good thermal stability up to approximately 280–300 °C, making it suitable for standard melt-processing of common thermoplastics. Its molecular structure supports resistance to degradation during high-shear compounding and extended residence times.
Q3: Is HR02 suitable for food-contact plastic applications?
A: HR02 is designed for use in non-food-contact plastic applications. For food-contact compliance, specific regulatory evaluations must be conducted per regional requirements; this grade is not pre-certified for such use.
Q4: What is the typical dosage range when using HR02 in polyolefin masterbatches?
A: Dosage generally ranges from 0.1% to 2% by weight, depending on the desired shade strength, polymer type, and processing method. It is typically used at low concentrations due to its high tinctorial strength and efficient dispersion characteristics.
