Clariant Renol Yellow GG-HW 30 Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary application field for Renol Yellow GG-HW 30?

A: Renol Yellow GG-HW 30 is specifically developed for high-temperature and demanding polymer applications, particularly in polyolefins such as PP and PE—commonly used in injection molding, blow molding, and fiber spinning where thermal stability and dispersion performance are critical.

Q2: How does GG-HW 30 differ from standard Renol Yellow grades?

A: The “HW” designation indicates enhanced heat stability and improved compatibility with hydrophobic polymer matrices. Compared to conventional yellow pigment grades, GG-HW 30 offers superior resistance to thermal degradation during high-shear processing and maintains consistent hue and strength at elevated melt temperatures.

Q3: Is this pigment suitable for food-contact plastics?

A: Renol Yellow GG-HW 30 is designed for use in polymers intended for non-food-contact applications. For food-contact compliance, customers must consult Clariant’s regulatory documentation and verify suitability against applicable regional requirements—this grade is not pre-approved for direct or indirect food contact without further assessment.

Q4: What is the recommended dosage range in polypropylene?

A: Typical usage levels in polypropylene range from 0.1% to 2.0% by weight, depending on the desired shade intensity, processing conditions, and final part requirements. Optimal loading should be determined through formulation trials to balance color performance, dispersion quality, and mechanical properties.

Q5: Does this pigment require surface treatment or dispersing aids for optimal performance?

A: Renol Yellow GG-HW 30 is supplied in a pre-treated, highly dispersible form optimized for direct incorporation into polyolefin melts. While masterbatch production typically achieves excellent results without additional dispersants, fine-tuning may be beneficial in complex formulations or when targeting ultra-high-gloss or thin-wall applications.
