Q1: What is the primary thermal stability range for CATHAYTHERM YA22XRS?
A: CATHAYTHERM YA22XRS is engineered for high-temperature applications and maintains color integrity and chemical stability in polymer processing environments typically up to 300°C, making it suitable for engineering thermoplastics and heat-intensive compounding processes.
Q2: Is YA22XRS compatible with polyolefins such as PP and PE?
A: Yes — YA22XRS demonstrates excellent compatibility and dispersion stability in polyolefin matrices, including homopolymer and copolymer PP and HDPE/LDPE, without requiring specialized surface treatment or coupling agents under standard melt-processing conditions.
Q3: How does YA22XRS perform under UV exposure and weathering?
A: As an inorganic pigment based on stable metal oxide chemistry, YA22XRS offers inherently high UV resistance and long-term outdoor durability, with minimal fading or chalking observed in stabilized polymer systems exposed to natural or accelerated weathering conditions.
Q4: Can YA22XRS be used in food-contact compliant compounds?
A: While YA22XRS itself contains no organic dyes or volatile impurities, regulatory compliance for food-contact applications depends on the full formulation, processing conditions, and applicable regional requirements; users must conduct full migration testing and obtain approval from relevant authorities before use in such applications.
Q5: What is the typical dosage range for achieving optimal color strength and opacity?
A: Dosage depends on the base polymer, desired shade depth, and processing method, but YA22XRS is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight — due to its high intrinsic tinting strength and fine particle morphology.
