Eastman: Fiber laser welding will boost medical role of copolyesters


Use of high-performance fiber lasers introduced at NPE 2012 may significantly advance use of a variety of clear plastics in medical applications, such as fluid bags now made from polyvinyl chloride.

Eastman Chemical announced at MD&M West held in Anaheim, CA last month that the technology developed by IPG Photonics (Oxford, MA) has significant potential for advancing its clear copolyester plastics.

One major reason is that the fiber laser process developed by IPG Photonics (Oxford, MA) does not require energy-absorbing additives. Medical device OEMs are pushing suppliers to remove as many chemicals from formulations as possible. Eliminating additives, such as Clearweld inks or Lumogen dyes also saves money....
