Fortschritte bei walzbaren Urethanen

von Thomas L. Jablonowski, Dr. Curt Reichel

Millable urethanes are polymers that are known for their excellent abrasion and strength properties while being able to be processed on conventional rubber equipment. Existing millable urethanes are primarily used in applications that take advantage of these properties. A newly developed polymer also takes advantage of and improved upon urethane’s excellent permeability and fluid resistance for automotive applications. A second polymer has been developed for FDA applications requiring contact with wet foods. Applications for this polymer can include belting for food processing, milking inflations, etc. Development of these polymers and compounding studies for specific applications will be discussed. Compounding techniques for achieving high hardness compounds with excellent processability and properties will also be evaluated.
