Our company mainly develops lightweight ducting for rail cars as well as insulation and sound-absorbing materials. We have been developing and supplying floor and side riser ducts for the new Shinkansen bullet trains for 10 years and continue to do so today. Our curled carbon fiber is used as rail car insulation. Moreover, we also develop cleaning systems for dirty rail car bodies, and we are currently engaged in the development of coatings that prevent dirt accumulation.
