Permlastic Rubber Base Impression Material
Permlastic® is a polysulfide, condensation-cured, elastomeric impression material in three viscosities.
Regular Permlastic is recommended for partial- orfull denture impressions because it has a high degree of flow that willregister the finest detail. While usually used in single-mix, it can beused with Light-Bodied Permlastic for crown and bridge impressions. Itwill not tear when being removed from undercuts. Light-Bodied Permlastic is themost free-flowing of the Permlastic materials. It is excellent forinlay and fixed bridge impressions. Light-Bodied Permlastic is asyringe material that is usually used with Heavy-Bodied Permlastic.Light Body bonds completely with both Regular and Heavy Bodies,resulting in impressions with great accuracy and fine definition. Heavy-Bodied Permlastic is formulated for usewhenever a stiffer material is indicated. The heavy body consistencyresults in optimum compression of the Light-Bodied Permlastic in adouble-mix, copper-band impression.
