MuCell technology |
The MuCell technology is
a processing technology in which supercritical
gas is diffused into molten polymer to develop
foamed plastics with cell sizes between 0.5
- 100µm. On of the greatest advantages
of this technology is 20 - 30% reduction in
product weight without significant loss of mechanical
properties of conventional non-foamed plastics.
* MuCell is a registered trademark of Trexel
Inc. |

|
| The MuCell technology is
based on a patent awarded to Dr. Nam P. Suh
et al. at the MIT (Massachusetts Institute of
Technology). Trexel, Inc. based in Boston, USA
is the exclusive licensor of the proprietary
MuCell technology. On the basis of the fundamental
patent of MIT, Trexel Inc. invested tens of
millions of dollars on research and development,
successfully established and commercialized
the technology related to extrusion molding,
injection molding and blow molding. More than
2000 patents applied by Trexel Inc. form barriers
that prevent competitors seeking for the development
and commercialization of similar products from
entering the market. |
