Description
Nicem® Green High Tear Silicone is formulated for use with tin and lead alloys when there is a need for additional tear strength. It replaces the now-discontinued Marathon and Millennial Silicone Rubbers. Because of its lower cost versus the Nicem Blue and Yellow silicones, it is also commonly used for shorter runs in zinc alloys. Like all Nicem silicone, Nicem® Green High Tear Silicone 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.
