Polyvinyl chloride (PVC) processing presents unique challenges for pigment selection. The pigment must withstand the thermal processing temperatures of PVC, resist sulfur-induced discoloration, and remain stable over the product’s lifecycle.
Ultramarine blue pigment meets all these requirements. It is highly resistant to migration and does not plate out during PVC processing. Its inorganic nature ensures compatibility with PVC stabilizer systems.
Our ultramarine blue for PVC at Shree Krishna Ultramarine Pigments (P) Limited is manufactured with controlled particle size distribution to ensure easy dispersion in PVC calendering, extrusion, and injection molding processes.
One important consideration when using ultramarine blue in PVC is its sensitivity to acid. In acidic environments, the pigment can lose its blue hue. However, when used in standard PVC formulations with appropriate stabilizers, this is not a concern.
With over four decades of experience, SKU Pigments offers technical support to PVC manufacturers to help them select the optimal ultramarine blue grade and dosage for their specific application requirements.
