Q1: What are the primary application areas for Clariant DG Pigments?
A: Clariant DG Pigments are specially developed for demanding applications in plastics, including food-contact packaging, medical devices, and high-clarity consumer goods. They are widely used in polyolefins, PET, PS, and engineering thermoplastics where excellent dispersion, thermal stability, and color consistency are required.
Q2: Are Clariant DG Pigments suitable for food-contact compliant formulations?
A: Yes — Clariant DG Pigments are designed with regulatory compliance in mind and many grades meet global food-contact requirements, including FDA 21 CFR and relevant EU framework provisions. Final compliance depends on the specific grade, polymer matrix, processing conditions, and end-use application, so validation with the intended formulation is recommended.
Q3: How do Clariant DG Pigments differ from conventional pigment preparations?
A: DG Pigments feature Clariant’s proprietary dispersion technology, offering superior pigment deagglomeration, enhanced rheological behavior in masterbatches, and improved batch-to-batch reproducibility. They are engineered to minimize plate-out and filter clogging during extrusion, especially in high-output or high-precision processes.
Q4: What is the typical dosage range for Clariant DG Pigments in plastic masterbatches?
A: Dosage varies based on desired color strength, polymer type, and processing method, but DG Pigments are typically used at low concentrations due to their high tinctorial strength and efficient dispersion. In standard masterbatch applications, loading generally ranges from 0.1% to 2% by weight relative to the final compound.
Q5: Can Clariant DG Pigments be processed using standard compounding equipment?
A: Yes — DG Pigments are compatible with conventional twin-screw extruders, high-speed mixers, and hot-melt pelletizers. Their optimized particle morphology and surface treatment support smooth feeding, stable throughput, and minimal wear on processing hardware under typical industrial conditions.
