UV Absorber, Optical Brightener, Pigment For PPVC

Polyvinyl chloride abbreviated to PVC, PVC comes in two basic forms: rigid (abbreviated as RPVC) and flexible. PPVC is abbreviated of plasticized polyvinyl chloride.

PPVC can be made softer and more flexible by the addition of plasticizers, In this form, it is also used in plumbing, electrical cable insulation, imitation leather, signage, phonograph records, inflatable products, and many applications where it replaces rubber.

Things to know when selecting pigments for PVC

1.Only pigment, no dyes for PVC.

2. Light Fastness, it is suggested light fastness level above 5 degrees.

3. Immigration, normally use bright color and good migrate resistance pigments.

4. Electrical properties, when coloring insulation materials,  electrical properties shall take into consideration as pigment could somewhat decrease PVC electrical properties.

5. Heat resistance, for RPVC, middle to high heat resistance is required.

6. Safety, for food and medical usage PVC, no toxic and chemosmotic shall be allowed.
