Plastisol

Plastisol is a liquid dispersion of finely divided resin in a plasticizer, q.v.. Polyvinyl chloride resin dispersed in a plasticizer is a typical plastisol. It is usually 100% solid with no volatiles; when volatile content exceeds 5% of the total weight, it is called an organosol. When the plastisol is heated, the plasticizer solvates the resin particles and the mass gels. With continued application of heat, the mass fuses to become a conventional thermoplastic material.

Remarks: Plastisols are useful for molding, casting films or coating. They are often used without volatile or high processing temperatures. Some plastisols or organosols may be heat or shear-sensitive.

Pump Notes: Check with supplier of material for liquid characteristics before making a pump recommendation.
