Thermoset laminates were first developed by Leo Baekeland in 1907 when he introduced Bakelite, a non-flammable thermoset utilizing phenolic resin with a paper substrate. This material has been used in everything from engine parts to jewelry to electronics. Products that were originally made from Bakelite include telephone mouth and ear pieces, buttons, and frying pan handles.
Ryertex was first introduced in the 1930’s as a replacement to metal. Demand grew shortly thereafter as World War II put a strain on the nation’s metal supply and Ryertex was quickly seen as a replacement in a wide variety of industrial applications.
Today, Ryertex is a trade name of W.S. Hampshire who has built an outstanding reputation for producing high quality, custom fabricated parts for use in many industrial applications including bearings, bushings, and other wear parts.
