Polygon Company – Innovation Beyond Metals

Who is Polygon?

Always the pioneer, Polygon invented the composite bearing, non-gelcoat composite pneumatic cylinders, composite laparoscopic surgical tubing, and remains one of the foremost suppliers of dielectric motor insulation worldwide.

By combining the power of a strong engineering staff with capable and timely manufacturing, Polygon's vertical integration assures quality products which are practical to produce.


Founded in 1949 by a chemist working on advanced composite materials during World War II at Wright-Patterson Air Force base, Polygon Company has grown into an engineered materials company with manufacturing facilities and distributors worldwide. Polygon’s original and ongoing patents stand as a hallmark in the development of fiber reinforced epoxy resin composite technology.
