Q1: What is the primary application field for Sanodure Olive Brown 2R?
A: Sanodure Olive Brown 2R is specifically developed for coloring polyolefin-based packaging materials, especially where high thermal stability and excellent dispersion are required—such as in injection-molded or blow-molded food contact containers and closures.
Q2: Is this pigment suitable for food-contact applications?
A: Yes, Sanodure Olive Brown 2R is formulated to comply with global food-contact regulations for polyolefins, including FDA 21 CFR and EU Framework Regulation (EC) No. 1935/2004, subject to proper formulation and processing conditions.
Q3: How does Sanodure Olive Brown 2R perform under high-temperature processing?
A: It exhibits very good thermal stability, maintaining consistent color and minimal degradation during standard polyolefin processing up to 260 °C, making it suitable for demanding operations like hot-fill packaging production.
Q4: What is the typical dosage range in polyolefin compounds?
A: Dosage depends on the desired shade intensity and base polymer, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—with optimal dispersion achieved using standard masterbatch or direct addition techniques.
Q5: Does this pigment require special handling or pre-treatment before use?
A: No pre-treatment is needed. Sanodure Olive Brown 2R is supplied as a free-flowing, dry powder optimized for direct incorporation or masterbatch preparation. Standard industrial hygiene practices for pigment handling are recommended.
