What are the characteristics and application areas of pigmented carbon black for PVC foam

The pigmented carbon black is generally good for coloring plastics, and can be selected according to the coloring characteristics or physical and chemical properties, and the choice of coloring carbon black is basically determined by the blackness of the finished product. So it is used in PVC foam what are the characteristics and application in those areas?
Pigmented carbon black develops and designs color masterbatch series products: pigmented carbon black. It has the characteristics of high blackness, high coloring, high gloss, excellent blue phase and excellent dispersibility and circulation.
It is widely used in plastic masterbatches, polypropylene cloth, polyester fiber plastic masterbatches, pvc wire and cable, color paste, leather products, paper industry, waterproof sealant and other crafts.
The surface organic chemical properties of pigmented carbon black for PVC foam masterbatch: The surface organic chemical properties of pigmented carbon black for PVC foam masterbatch vary according to the manufacturing method. The surface layer of carbon black has different oxygen content functional group isomerization.
Generally, carbon black with high oxygen content functional group isomerization has high volatility, good color adjustable characteristics and high fluidity. The volatile content of carbon black is expressed as a percentage of net weight damage after heating to 825±25oC.
