ChronoSil is a family of polycarbonate based silicone elastomers. These biocompatible materials maintain the inherent benefits of polycarbonate-based urethanes, including high pressure resistance, tensile-strength and superior chemical resistance combined with silicone’s industry recognized advantages such as heightened elongation, superior elasticity and a low coefficient of friction.
Consistent with other polycarbonate-based materials, ChronoSil can be synthesized to provide targeted mechanical properties and is resistant to Environmental Stress Cracking (ESC).
These products are adaptable to most standard manufacturing processes and are available in hardnesses ranging from 75 Shore A to 75 Shore D.
