Dispersant for plastic additives

Plastic additive dispersant is a common plastic additive used to improve the dispersion performance of solid additives such as pigments and fillers with plastic substrates in plastic processing. They can evenly disperse pigments and fillers in the plastic matrix, enhancing the color uniformity and physical properties of plastic products. The following are several commonly used dispersants for plastic additives:

Anionic dispersants: Anionic dispersants have excellent dispersion properties and are suitable for many plastic systems. They are usually composed of hydrophobic and hydrophilic groups and can form surfactants in the plastic matrix, thereby achieving good dispersion of pigments or fillers.

Non ionic dispersants PAAS : Non ionic dispersants are also commonly used plastic additives, usually composed of polyhydroxy compounds such as polyethers, polyols, etc. These dispersants can be adsorbed on the surface of solid particles through their hydrophilic groups, while their hydrophobic groups are compatible with the plastic matrix, achieving good dispersion of pigments or fillers.

Organic phosphate dispersants: Organic phosphate dispersants are a special type of dispersant that react with metal ions or oxide surfaces to form complexes or complexes, thereby achieving the dispersion of pigments or fillers. These dispersants can improve the strength and heat resistance of plastic products.

It should be noted that the selection of suitable plastic additive dispersants should be based on the specific plastic system, additive type, and process conditions. In addition, the operation should be carried out in accordance with relevant technical guidelines and safety standards, and the correct operating procedures should be followed.
