Nylon 11

Description

Nylon 11 is composed of polymerized 11-amino-undecanoic acid. Nylon 11 was originally made from castor bean oil and marketed under the trademark of Rilsan®. Nylon 11 fibers have similar properties to nylon 6 and 6,6. Nylon 11, however is less dense, melts at a lower temperature and has better dimensional stability. It is often used for brush bristles, lingerie, bulked yarns, and injection molded plastics.
