ChronoSil®

STRONG YET SUPPLE: THE POWER OF POLYCARBONATE MEETS THE SOFTNESS OF SILICONE. 

Thermoplastic Silicone Polycarbonate Elastomers

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.

ChronoSil processing can be optimized by drying to a moisture content equal to or less than 0.05% by weight prior to melt processing.  

Typically, the pellets must be dried for 3-4 hours with a dryer inlet air temperature of 180ºF +/- 20ºF. We recommend a machine-mounted desiccant-type hopper dryer, capable of reaching and maintaining a dew point of -40ºF.  If dry times are in excess of 8-10 hours, a hopper dryer temperature of 120-150ºF is usually sufficient to achieve optimal moisture content.
