Highly dispersible in rigid and flexible PVC compounds without requiring pre-dispersion.
Excellent thermal stability up to 200 °C, minimizing color shift during high-speed extrusion and calendering.
Low dust generation and improved handling safety due to optimized particle surface treatment.
Consistent jetness and opacity across diverse PVC formulations, including calcium carbonate-filled systems.
Compatible with common PVC stabilizers (e.g., Ca/Zn, Pb-free, and organotin systems) without adverse interaction.
Rigid PVC profiles for window frames and door systems.
PVC flooring (sheet, tile, and luxury vinyl tile – LVT).
Wire and cable jacketing compounds.
PVC pipes and fittings for potable water and construction applications.
Automotive interior trims and under-hood components.

Q1: What is the primary application of Telasperse PVC Black 41?
A: Telasperse PVC Black 41 is specifically engineered for use in rigid and flexible PVC compounds, including profiles, pipes, cables, flooring, and injection-molded articles where high jetness, excellent dispersion, and thermal stability during processing are required.
Q2: Is this pigment suitable for food-contact or potable water applications?
A: Telasperse PVC Black 41 is designed for general-purpose PVC applications. For food-contact or drinking water systems, regulatory compliance must be verified case by case with final formulation testing and relevant local authority requirements — Clariant does not pre-certify end-use compliance.
Q3: How should Telasperse PVC Black 41 be incorporated into PVC formulations?
A: It is typically added during dry blending or high-shear compounding stages. Good dispersion is readily achieved due to its optimized surface treatment, and it performs well in both internal mixers and twin-screw extruders commonly used in PVC processing.
Q4: Does this pigment offer resistance to migration and blooming in flexible PVC?
A: Yes — Telasperse PVC Black 41 exhibits low tendency toward migration and blooming in plasticized PVC systems, thanks to its tailored molecular compatibility with common phthalate and non-phthalate plasticizers.
Q5: What is the typical dosage range for achieving full black opacity?
A: Dosage depends on formulation requirements, PVC type, and desired opacity level, but it is generally effective at concentrations ranging from 0.1% to 2% by weight of the total compound.
