Nano-alloy Resin

Toray's innovative nano-alloy technology, developing frontier polymers

Pioneering polymeric materials created with innovative nano-alloy technologies

We created the new technology for the first time, using the nanotech field which combines two different types of polymers (into alloys) while bringing out the outstanding properties of both polymers. We started to market nano-alloys for use in automobile parts, electrical and electronic components and other injection molding applications, developing transparent sheets, decorative film and other new applications. This technology is also being applied to polylactide alloys, taking advantage of these inherent properties for moving into electrical and electronic fields in which it was difficult to put conventional polylactide to work.

Development Product Performance Comparison

Features

  • Controlability of the phase structures created by the different polymers through self-assembled alloy technology
  • Stability to form the 3-dimensional continuous structures at the nano-level
  • Possibility to create frontier polymers which was difficult to be created by the conventional technology
  • Possibility to expand the range of polymer combinations

Development Applications

  • Injection molding items: balance competing properties for high impact resistance of PC and high chemical resistance of PBT
  • Films, sheets: balance competing properties for the high transparency of PC and high chemical resistance of PBT

Impact-absorbing Plastic

In the gProject on Nano-structured Polymeric Materialsh of the New Energy Development Organization (NEDO), we had been promoted joint research with a group of Professor Takashi Inoue in Yamagata University and developed a revolutionary nano-alloy plastic. During normal use, this nano-alloy has properties equivalent to plastic in terms of strength and rigidity. When exposing the alloy to collisions or other fast and powerful impact, it transforms into a rubber-like consistency in taking on properties that effectively absorb the impact. As a pioneering material that rewrites the common wisdom on plastic performance, this nano-alloy will pave the way to expansion into totally new applications and fields.
