Foster distributes high-strength polyamide to North American medical manufacturers


Foster Polymer Distribution, a business unit of Foster Corp. (Putnam, CT) specializing in the distribution of medical polymers and additives, has partnered with Mitsubishi Gas Chemical (New York) to distribute MX nylon to the North American medical market. MX nylon, a meta-xylene diamine polyamide, offers mechanical and barrier properties suitable for molded components and devices, and for use in medical packaging applications.

Metal replacement is one area where the material has tremendous potential. Polymer components are frequently preferred over metal in medical equipment since they do not interfere with magnetic resonance imaging (MRI), computerized axial tomography (CAT), fluoroscopy and x-ray imaging. MX nylon is a high-strength metal replacement material with a flexural modulus 50% greater than traditional polyamide 6/6 and 15% greater than polyetheretherketone (PEEK). It also has a cost advantage, since it is priced 25% less than PEEK, according to Foster Corp., making MX nylon an economical option for high-strength components that must be radiolucent.
