Q1: What is the primary application of Telasperse PVC Black 24 Gran?
A: Telasperse PVC Black 24 Gran is specifically engineered for coloring rigid and flexible PVC compounds, including profiles, pipes, cables, flooring, and injection-molded articles where high jetness, good dispersion, and thermal stability during processing are required.
Q2: How does the granular form benefit PVC processing?
A: The free-flowing granule format ensures excellent dosing accuracy, minimizes dust generation during handling, and promotes rapid and uniform dispersion in PVC dry-blends—reducing mixing time and supporting consistent color development in both calendering and extrusion processes.
Q3: Is this pigment suitable for food-contact or potable water applications?
A: Telasperse PVC Black 24 Gran is formulated for general-purpose PVC applications. For food-contact or drinking water use, regulatory compliance must be confirmed case-by-case with Clariant’s technical team and relevant local authorities, as suitability depends on final compound composition, processing conditions, and end-use requirements.
Q4: What is the typical dosage range in PVC formulations?
A: Dosage depends on the desired black intensity and PVC matrix characteristics, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—due to its high tinting strength and optimized particle morphology.
Q5: Does this product contain heavy metals or restricted substances?
A: Telasperse PVC Black 24 Gran is manufactured without added heavy metals such as lead, cadmium, mercury, or hexavalent chromium, and is designed to support compliance with major global regulatory frameworks for PVC pigments—including RoHS and REACH—subject to final formulation validation.
