Distributor of medical polymers and additives for Foster Polymer Distribution, a unit of Foster Corp., Putnam, Conn., has officially partnered with Japan’s Mitsui Chemicals to distribute the latter’s TPX polymethylpentene (PMP) polyolefin copolymer to the North American medical markets.The low-surface tension of this copolymer is said to be ideally suited for mandrels used in the manufacturing of precision medical tubing and release films for shipping and handling applications.

Precision medical device components, such as catheters, often require mandrels to support thin-wall sections and retain tolerances during manufacturing. TPX polyolefin copolymer has a melting point range of 220C-240C (428-464F) and a surface tension 38% lower than HDPE, a common mandrel material used for catheter manufacturing. It also has a specific gravity of 0.83, which is 13% lower than HDPE and represents the lowest density of any commercially available thermoplastic. As a result, TPX-based films minimize weight which can reduce transportation costs.
