Discover the Anti-blocking Agent for PVC Products

Anti-blocking agent (also known as anti-caking agent) is a chemical additive used to prevent the formation of blocks or agglomerates in powdered, granular, or bulk solid materials. These agents are typically added to improve the flowability, dispensability, and handling properties of the materials during processing, storage, and transportation.

Anti-blocking agents work by creating a thin layer between particles, which reduces the friction and adhesion between them. This layer helps to prevent the particles from sticking together and forming blocks or agglomerates.

Common types of anti-blocking agents include silica, magnesium silicate, calcium silicate, talc, and various polymers. The selection of the appropriate anti-blocking agent depends on the specific application, the type of solid material, and the desired properties.
