Polyurethane can be processed in a number of forms including rigid, cast and flexible. It can also be used for coatings, adhesives and sealants. Each type of polyurethane processing requires its own kind of equipment, but all of the machinery generally have one thing in common: chemicals (usually a polyol or polyether, and an isocyanate or diisocyanate) are stored separately and then combined in the mixing head, forcing a chemical reaction that creates the polyurethane. The companies below manufacture or supply polyurethane processing equipment. Click on a link to view a company's information.
