Pure Sil

Pure Sil 20 and Pure Sil 30 are 2-part, tin-catalyzed, condensation curing silicone rubbers in 20 Ashore and 30 A shore hardness. Pure Sil rubbers have excellent tear resistance and exhibit low linear shrinkage. Pure Sil 20 is softer and easier to demould from fine details. Both rubbers are suitable for economical mould making for the casting of resins, gypsum, candle wax and similar materials.
