Q1: What is the primary application of Sanodure Black CRO Pigment?
A: Sanodure Black CRO Pigment is specifically developed for coloration of polyolefin-based food contact materials, particularly in injection-molded and blow-molded packaging applications where high thermal stability and low extractability are required.
Q2: Is this pigment compliant with food contact regulations?
A: Sanodure Black CRO Pigment is formulated to meet the general requirements for pigments used in food-contact plastics under major global frameworks, including FDA 21 CFR and EU Regulation (EC) No 1935/2004. It is not intended for use in applications requiring direct aqueous or fatty food simulants without prior validation by the end-user.
Q3: How does Sanodure Black CRO differ from standard carbon black pigments?
A: Unlike conventional carbon blacks, Sanodure Black CRO is a surface-treated, highly purified pigment with optimized particle dispersion and reduced volatile organic content—designed to minimize odor, improve color consistency, and support regulatory compliance in sensitive food packaging applications.
Q4: What is the recommended dosage range for optimal performance?
A: Typical dosage ranges from 0.1% to 2% by weight in polyolefin matrices, depending on desired shade depth, processing conditions, and final application requirements. Lower concentrations are generally sufficient due to its high tinting strength and efficient dispersion characteristics.
Q5: Can Sanodure Black CRO be used in high-temperature processing such as injection molding?
A: Yes—the pigment exhibits excellent thermal stability up to typical polyolefin processing temperatures (e.g., 200–260 °C), maintaining color integrity and minimizing degradation-related volatiles or discoloration during extended residence times.
