Plastisols

Plastisols are a dispersion of fine polyvinyl chloride (PVC) particles in a plasticizer. When heated, the plasticizer is absorbed by the PVC particles, causing them to fuse into a flexible, solid material. This process is known as gelation or fusion. Plastisols are typically viscous liquids at room temperature.

The properties of a plastisol can be significantly altered by varying the type and amount of plasticizer used, as well as by adding other additives such as fillers, pigments, heat stabilizers, and blowing agents. These additives can influence flexibility, hardness, color, durability, and foaming characteristics.

Plastisols find a wide range of applications due to their versatility. They are commonly used in the production of coated fabrics for items like tarpaulins, tents, and protective clothing. They are also employed in screen printing inks, where they allow for the creation of durable and vibrant graphics on textiles. Other uses include dip coating for tools and handles, slush molding for automotive interiors and toys, and as sealants and adhesives. The ability to form a continuous film upon heating and their inherent flexibility make them a valuable material in many manufacturing processes.
