Seals

Greene, Tweed & Co.in semiconductor fabrication are usually molded from elastomeric compounds, or machined from polymeric materials. They are intended to form a barrier to the passage of fluids or gases within the systems (or components) in which they are used. Greene, Tweed & Co.in semiconductor processing must be resistant to chemical exposure, high temperatures, extreme pressure, aging and cyclic motion, and must form a reliable seal without bonding to the sealing surface(s). The three basic types of semiconductor seal installations are: dynamic seals (installed on surfaces that move relative to each other in a reciprocating or rotary motion); semi-dynamic seals (installed onto mating surfaces that move relative to each other in an "up-down" motion); and static seals (installed onto mating surfaces that do not move relative to each other).
