Silicone sealing material exhibiting high stress relaxation

The invention provides for a method of making simple or complex extruded gel profiles and the created article. In a particularly preferred embodiment, the method involves the extrusion of a silicone gel composition through a die into a heated fluid to complete the cure of the gel as well as to produce the desired gel profile shape. Shapes such as stars, trapezoids, cusped squares, cusped triangle, triangles and the like can be fabricated according to the method.

Extruded silicone gel profiles

A liquid crystal display is made from an encapsulated liquid crystal structure comprising a liquid crystal composition dispersed in a containment medium. Selected additives may be added to the encapsulated liquid crystal structure to improve performance characteristics such as the operating field, the hysteresis, and the voltage holding ratio.
