B.F.Goodrich Chemical raw
materials
Willard drain valves, using a diaphragm molded of Hycar by Immel Engineering, Dallas, are used in commercial washing machines manufactured by Cook Machinery, Inc., also of Dallas. B.F.Goodrich Chemical Company supplies the Hycar nitrile rubber.
Detergents tough on rubber parts as well as dirt .,. till Hycar solved the problem The drain valve for these commercial washing machines is controlled by a solenoid through a rubber diaphragm. Chemicals commonly encountered in soaps and detergents created a problem—till these diaphragms were made of Hycar nitrile rubber. Hycar is a tough rubber —unaffected by hot water, excessive
alkalinity or chemicals. It resists oils, greases, and other hydrocarbons, retaining its resilience and flexibility over a wide temperature range. Next time you have a rubber problem to solve, it may pay you to know about the unique advantages Hycar brings. For more information, write Dept. MG-3, B.F.Goodrich Chemical Company, 3135 Euclid
