Q1: What is the primary application field for PV Fast Red B-LHC?
A: PV Fast Red B-LHC is specifically developed for high-performance coloring of polyvinyl chloride (PVC), particularly in rigid and flexible applications such as profiles, cables, flooring, and medical tubing where excellent heat stability and migration resistance are required.
Q2: How does PV Fast Red B-LHC perform under processing conditions typical for PVC?
A: This pigment exhibits very good thermal stability during standard PVC processing—such as calendering, extrusion, and injection molding—without significant color shift or degradation, even at elevated temperatures up to 180–200 °C for short residence times.
Q3: Is PV Fast Red B-LHC suitable for applications requiring low extractability?
A: Yes—PV Fast Red B-LHC is engineered for low extractability in plasticized PVC systems, offering improved resistance to migration into adjacent materials or solvents compared to conventional red pigments, making it well-suited for multi-layer or contact-sensitive applications.
Q4: What is the typical dosage range when using this pigment in PVC formulations?
A: Dosage depends on the desired shade strength and final application requirements, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight in the PVC compound—with optimal dispersion achieved using standard high-shear mixing equipment.
