PVC masterbatch pigment carbon black application instructions:   
PVC masterbatch is a special masterbatch for PVC. PVC materials are often added stabilizer, lubricant, auxiliary processing agent, color, impact resistance agent and other additives in actual use.   Non - flammability, high strength, weather resistance and excellent geometric stability.   PVC is very resistant to oxidants, reducing agents and strong acids.   However, it can be corroded by concentrated oxidizing acids such as sulfuric and nitric acid and is not suitable for contact with aromatic and chlorinated hydrocarbons.   
The processing of masterbatch will add pigment carbon black to make its blackness more black.   And good dispersion performance, good gloss and more durable performance characteristics.
