Formulated and blended using only the highest quality polymers and fillers, the range of silicone rubber compounds offered by The Contenti Company covers the entire spectrum of centrifugal rubber mold casting applications.
Every silicone rubber mold set has a nominal thickness of 1" and consists of four 1/4" thick sections. The term "durometer" used below refers to the relative hardness of a rubber compound when cured. The higher the durometer, the harder the rubber compound is.
