High-consistency elastomers available for a wide range of applications.

A family of versatile elastomers was designed for optimal performance. VersaSil³, produced by NuSil Technology (Carpinteria, CA; 805/684-8780), includes three base stocks, which, when vulcanized, produce tough, durable elastomers with nominal Shore-A durometers of 30, 50, and 70, respectively. The base stocks may also be blended to produce elastomers of intermediate durometer. VersaSil³ was developed for volume users who require maximum versatility. Its applications include extrusion, transfer and compression molding, and calendering. The elastomers' advantages include translucency, variable table life, wide processing parameters, high tear strength, low cure temperatures, and relatively low cost, among others.
