Rubber Extrusion Technology

Learn applicable basic information on all aspects of the rubber extrusion process. Build a knowledge base that encompasses products ranging from intricate profile extrusions to tires, using compositions ranging from a single thermoplastic elastomer to multiple dense and cellular compounds coextruded with carriers and reinforcements.

This course can be applied to the Elastomer Technology Certificate.
