Light body is excellent for inlay and fixed bridge impressions 2. Regular body is recommended for partial- or full-denture impressions 3. The denser viscosity of heavy body results in optimum compression of the light body in a double-mix or copper-band impression. Polysulfide Impression Material Permlastic is a polysulfide, condensation-cured, elastomeric impression material in three viscosities.Regular Permlastic is recommended for partial- or full denture impressions because it has a high degree of flow that will register the finest detail.
