Q1: What is the primary thermal stability range for CATHAYTHERM ZF15C?
A: CATHAYTHERM ZF15C is engineered for high-temperature applications and maintains color integrity and chemical stability in polymer processing environments typically up to 350°C, making it suitable for engineering thermoplastics and high-heat compounding processes.
Q2: Is this pigment compatible with polyolefins such as PP and PE?
A: Yes, CATHAYTHERM ZF15C exhibits excellent compatibility with polyolefins and demonstrates good dispersion stability during melt processing. It is commonly used in PP and HDPE applications where heat resistance and UV durability are required.
Q3: How does ZF15C perform under prolonged UV exposure?
A: As an inorganic pigment based on stabilized metal oxide chemistry, ZF15C delivers inherently high UV resistance and minimal fading or chalking, even in outdoor applications — performance that exceeds most organic pigments and many standard inorganic alternatives.
Q4: What is the typical dosage range when incorporating ZF15C into polymer masterbatches?
A: Dosage depends on the desired shade intensity and base polymer, but ZF15C is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight in final formulations — due to its high tinting strength and efficient dispersion characteristics.
Q5: Does ZF15C contain heavy metals restricted under RoHS or REACH?
A: CATHAYTHERM ZF15C is formulated without lead, mercury, cadmium, or hexavalent chromium, and complies with current RoHS and REACH SVHC requirements for general industrial use; however, end-use compliance should always be verified against specific regulatory thresholds and application conditions.
