Q1: What types of polymers is Colanyl Green GG 131 compatible with?
A: Colanyl Green GG 131 is specifically formulated for use in polyolefins such as PP and PE, and demonstrates good compatibility in thermoplastic elastomers and certain engineering plastics. Performance may vary depending on polymer polarity and processing conditions.
Q2: How should this color paste be incorporated into the base polymer?
A: It is typically introduced via masterbatch dilution or direct gravimetric dosing during extrusion or injection molding. Pre-blending with carrier resin or using high-shear mixing is recommended to ensure uniform dispersion and optimal color development.
Q3: Does Colanyl Green GG 131 offer heat stability suitable for high-temperature processing?
A: Yes, it is designed to withstand typical polyolefin processing temperatures up to approximately 260 °C, maintaining color integrity and minimizing thermal degradation under standard melt-processing conditions.
Q4: Is this product suitable for applications requiring low extractables or migration control?
A: Colanyl Green GG 131 is formulated with high-molecular-weight components to support low volatility and reduced extractability in non-food-contact applications. For regulated food-contact or medical uses, consult Clariant’s regulatory documentation and conduct application-specific testing.
