Nicem® White Silicone is formulated for use as a backer for more expensive silicone compounds. Combining this compound with another, more expensive silicone helps you to reduce your total mold cost. Nicem® White can also be a good choice when casting uncomplicated pieces in tin alloys. It’s also a little harder than the other available compounds. Like all Nicem silicones, Nicem® White is formulated and blended using only the highest quality polymers and fillers.
Every silicone rubber mold set has a nominal thickness of 1" and consists of four 1⁄4" thick sections. The term "durometer" used in the table below refers to the relative hardness of a rubber compound when cured. The higher the durometer, the harder the rubber compound is.
