Q1: What types of polymer systems is HD-S Pigment compatible with?
A: HD-S Pigment is formulated for broad compatibility with thermoplastics including polyolefins (PP, PE), engineering plastics (ABS, PS, PC), and certain thermoplastic elastomers. Compatibility in reactive systems (e.g., polyurethanes or epoxies) should be verified through preliminary dispersion and stability testing.
Q2: How is HD-S Pigment typically incorporated into a polymer matrix?
A: It is commonly introduced via masterbatch dilution, dry blending prior to extrusion, or direct feeding in twin-screw compounding. For optimal dispersion, processing temperatures should remain within the thermal stability range of the pigment carrier system, and sufficient shear history is recommended.
Q3: Does HD-S Pigment offer resistance to migration and blooming in final applications?
A: Yes — HD-S Pigment is engineered with surface-treated particles and compatible dispersants to minimize migration and blooming, especially in non-polar matrices like polyolefins. Performance may vary depending on polymer polarity, crystallinity, and service temperature.
Q4: What is the typical dosage range for HD-S Pigment in colored compounds?
A: Dosage depends on the desired shade intensity and base polymer transparency, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in final compound formulations.
