Pigment carbon black CF-100 can be directly used as black pigment in PVC special color paste, and can also be used in the preparation of color masterbatch based on PVC resin. CF-100 has excellent covering power, tinting power and dispersion. At the same dosage, the special color paste has a lower viscosity, which can significantly improve the fluidity and has good compatibility with PVC resin. Compared with traditional pigment carbon black or black pigment, it can improve the dispersion performance of carbon black in PVC special color paste and PVC products, facilitate color matching, improve the tear elongation of products, and improve the elasticity of soft PVC products.
The PVC special color paste prepared from this pigment carbon black has excellent storage stability and thermal stability, is cost-effective, and can be used as a preferred new material for cost reduction and efficiency improvement.
Dosage
1. In PVC special color paste or PVC masterbatch, it can directly replace the pigment carbon black and other black pigments in equal amounts or in increments. (The specific dosage depends on the color matching requirements)
2. In order to improve the functionality of the special color paste and the thermal stability of PVC products, it can be used with an appropriate amount of our company's PVC special thermal stabilizer BM-1.
