Advanced Softmaterials Inc. (headquarters: Kashiwa City, Chiba Prefecture;
Representative Director and President: Yumiki Noda; abbreviation: ASM)*1 has developed
a sound absorption finishing agent called SeRM® SA (Sound Absorption) Mixture
containing SeRM® Super Polymer (supermolecule polyrotaxane)*2.
There are various types of sound absorbing materials, but existing porous materials
currently in use, such as non-woven fabric and urethane foam, exhibit sound absorbing
effects only at their respective natural frequencies.
However, coating with SeRM® SA Mixture makes it possible to greatly improve the soundabsorption coefficient, or shift the targeted frequency peak or the frequency band wherea sound absorbing effect is exhibited. This is a function which manifests itself due to thespecial structure of slide-ring material*3, which has moving cross-linking points, andthere is potential for combined use with a variety of porous materials.
Frequencies for which a sound absorption effect is needed vary depending on
differences in the application and paint, and material used also differ. Therefore, the planat our company for the time being is to continue sales to companies, while adjusting theblend of SeRM® SA Mixture to suit requirements in each case.

Established in 2005 with the aim of commercializing slide-ring material developed by
the University of Tokyo. Has obtained an exclusive license for comprehensive basic
patents pertaining to slide-ring material from the University of Tokyo, and is engaged in
product design, market development, and development of manufacturing methods.
※2 SeRM ® Super Polymer

A molecular aggregate in which multiple molecules of different types assemble, and arefounded through comparatively weak interactions.
By incorporating into various resins, it is possible to create these into materials withmoving cross-linking points, i.e., slide-ring material.

In March of this year, we concluded an exclusive
licensing agreement with Toyoda Gosei Co., Ltd.,
relating to dielectric actuator and dielectric sensor
applications employing the characteristics ofslide-ring material.
In addition, in the R&D program of Kohzo Ito,
Program Manager of the governmental Impulsing Paradigm Change through Disruptive
Technologies Program (ImPACT), new functions of slide-ring material have been
confirmed, such as Toray Industries, Inc.’s success in greatly improving impact resistance
while maintaining hardness, by incorporating slide-ring structure into network structureof polyamide.
