The leading chemical firm Mitsui Chemicals, has begun working on the development of a new, reusable 3D-printed mask with Nagoya University and a spinoff venture from Nagoya University. The new mask’s key feature is the fact that it not only filters out viral particles but also can be reused.
• The mask consists of a reusable body and a disposable filter.


  • Mitsui Chemicals will provide the nonwoven disposable filter, which removes viral particles.
  • Professor HORI of Nagoya University has produced the mask body using a 3D printer and is investigating enzyme preparations and various other antiviral agents that could be applied to it. Plans are to produce a mask with consideration of design and comfort while also ensuring that it provides outstanding protection against viruses.
  • In working together with a university, a university startup and a materials manufacturer, Mitsui Chemicals aims to offer socially beneficial solutions and tie this into the development of novel products that will help shape the next generation

In March 2020: Mitsui Chemicals, had expanded its production facilities for meltblown nonwovens at wholly owned subsidiary Sunrex Industry Co., Ltd., starting operations at the new facilities here this January. The move comes as an effort to respond to growing demand for industrial-use meltblown nonwovens, and will increase the Mitsui Chemicals Group’s overall production capacity for these materials by 50 percent.

In August 2019: Mitsui Chemicals, Inc. announced that it has entered into a materials sector-based partnership agreement with Plug and Play, LLC (Founder & CEO: Saeed Amidi), a Silicon Valley-based firm that supports the growth of startups with innovative technologies and ideas.
