Q1: What is the primary application field for Flexonyl Black PR 100?
A: Flexonyl Black PR 100 is specifically developed for coloring polyolefin-based packaging materials, including flexible films, rigid containers, and caps—particularly where high jetness, excellent dispersion, and thermal stability during extrusion or injection molding are required.
Q2: Is this color paste suitable for food-contact applications?
A: Yes, Flexonyl Black PR 100 is formulated to comply with global food-contact regulations for polyolefins, subject to final formulation validation and compliance with applicable regional requirements. Users must verify suitability for their specific processing conditions and end-use application.
Q3: How should Flexonyl Black PR 100 be incorporated into polyolefin compounds?
A: It is typically added directly to the base polymer via gravimetric or volumetric dosing systems during compounding—commonly using twin-screw extruders. Pre-blending with a portion of the base resin prior to main extrusion can support optimal dispersion and color uniformity.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and sources of heat. Avoid freezing. Stir gently before use if sedimentation occurs after prolonged storage, as the paste is designed for long-term physical stability under recommended conditions.
Q5: Can Flexonyl Black PR 100 be used in combination with other Clariant additives or pigments?
A: Yes, it is compatible with common Clariant additive solutions—including antioxidants, UV stabilizers, and processing aids—when used within typical dosage ranges. However, compatibility testing is recommended when combining with other colorants or functional additives to ensure no adverse interactions affect dispersion, hue, or performance.
