Permlastic is a polysulfide, condensation-cured, elastomeric impression material in three viscosities.
- Heavy body is used whenever a stiffer material is indicated
- Regular body is used for partial- or full denture impressions because it has a high degree of flow that will register the finest detail ad
- Regular body can also be used with light body for crown and bridge impressions and will not tear when being 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, resulting in impressions with great accuracy and fine definition
