The PlatSil® FS-Series (Fast-Setting) is Polytek's newest line of platinum-cured, room temperature curing (RTV) silicone rubbers. FS-Series products can be demolded faster than other PlatSil® silicones and also offer the benefit of having long pour times (~8 minutes) relative to their cure speed (~25 minutes). This allows for fast turn-around of molds and parts with sufficient time to mix and pour.
Polytek is now manufacturing three new molding latex rubbers. The NaturForm Series offers high-performing, natural molding latex rubbers that are most often used to make molds for casting plaster, concrete (e.g., veneer stone manufacturing and statuary) and limited casting with some resins.
