Permlastic is a polysulfide, condensation-cured, elastomeric impression material available in three viscosities.
- Heavy body is used whenever a stiffer material is indicated
- Regular body is used for partial- or full-denture impressions due to high flow that registers fine detail
- Regular body can also be used with light body for crown and bridge impressions and resists tearing when removed from undercuts
- Light body syringe material is used for inlay and fixed bridge impressions
- Light body bonds completely with both regular and heavy bodies, producing highly accurate impressions with fine definition
