Q1: What is the primary application field for Colanyl RL131-CN Color Paste?
A: Colanyl RL131-CN is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers used in food, personal care, and household product applications.
Q2: Is this color paste suitable for food-contact applications?
A: Yes — Colanyl RL131-CN is formulated using pigments and additives compliant with global food-contact regulations for polyolefins, subject to final regulatory verification within the target market and specific end-use conditions.
Q3: How should Colanyl RL131-CN be incorporated into polyolefin compounds?
A: It is typically added directly during extrusion compounding or masterbatch production. Good dispersion is achieved under standard melt-processing conditions for PP and PE, and dosage generally ranges from 0.1% to 2% by weight depending on required shade intensity and base polymer transparency.
Q4: Does this color paste offer good thermal stability during processing?
A: Yes — Colanyl RL131-CN is engineered for excellent thermal stability up to typical polyolefin processing temperatures, minimizing color shift or degradation during high-shear compounding and film extrusion.
Q5: Can Colanyl RL131-CN be used in combination with other Clariant additives?
A: Yes — it is compatible with common Clariant additive solutions such as light stabilizers, antioxidants, and antifog agents in polyolefin systems; however, compatibility testing under actual processing and end-use conditions is recommended.
