Pigments for PVC

Organic pigments for pvc sourced from India with grade selection, documents, and export support.

PVC ranges from rigid profiles to highly plasticised flexible films, and the plasticiser content makes migration the defining pigment concern. In flexible PVC, low-molecular-weight organics can migrate, bloom or bleed into adjacent materials, so migration-fast grades are essential. Rigid PVC additionally needs heat stability for the processing window and weather fastness for exterior profiles and window frames. Buyers sourcing from India should confirm migration and bleed resistance in plasticised systems, heat stability for their process, and exterior weathering for outdoor profiles. Compatibility with PVC stabiliser chemistry should also be verified before bulk purchase.

At a glance

What Pigments for PVC covers

Migration in flexible PVC

Plasticiser mobilises low-solubility pigments, so flexible PVC needs migration-fast grades that will not bleed into adjacent films, gaskets or packaging over time.

Rigid profile heat stability

Rigid PVC processing needs pigments stable across the extrusion window so profiles and pipes hold shade without degradation or plate-out on tooling.

Exterior weather fastness

Window frames and cladding endure years of sun, so specify high-weathering organics that resist fading and chalking in outdoor PVC profiles.

Stabiliser compatibility

Confirm the pigment works with your PVC stabiliser system and does not interfere with heat stabilisation or cause discolouration during processing.

Answers

Pigments for PVC — frequently asked questions

Why is migration the biggest issue in flexible PVC?

Plasticiser gives flexible PVC its softness but also mobilises soluble pigment, letting it migrate to the surface as bloom or bleed into contacting materials. This ruins appearance and can stain adjacent products, so flexible PVC requires high-molecular-weight, migration-fast organic grades verified under heat and pressure in the actual compound.

Do rigid and flexible PVC need different pigment grades?

Often yes. Rigid PVC has little or no plasticiser, so migration is minor and heat stability and weathering dominate. Flexible PVC's plasticiser makes migration critical. A grade ideal for rigid profiles may bleed in a soft film, so specify your PVC type and plasticiser level when sourcing.

What pigments suit exterior PVC window profiles?

Use high-weathering organics such as chlorinated phthalocyanine green and blue, quinacridones and DPP reds for coloured profiles, often alongside inorganics for durability. These resist UV fade and chalking over long outdoor service. Request weathering data representative of your climate and confirm heat stability for the extrusion process.

How do I check pigment compatibility with PVC stabilisers?

Run a processing trial in your actual formulation with the intended stabiliser and lubricant package. Watch for discolouration, plate-out on tooling, or reduced stabiliser performance. Ask the exporter whether the grade is recommended for your stabiliser type, and confirm no adverse interaction during heat history before committing to volume.
