Soft lining materials: composition and structure

Abstract

An analysis of five proprietary acrylic soft lining materials revealed that they can be classified into two groups. The first of these groups (Soft Oryl and Coe Soft) resemble the tissue conditioners in composition in that their liquid component contains no monomer. A study of their mechanical properties may reveal that these materials should, in fact, be classified as tissue conditioners. The second group (including Palasiv, Virina and Coe Super Soft) were more conventional acrylic materials which differed in the amount of plasticizer and the type of acrylic monomer used in the liquid component and in the nature of the polymer component.
