[Research and Development Case] Rubber × Resin Cross-linked Composite Material 'Rajikarokku'
Adopted by a major shoe manufacturer! Supporting rubber product development with extensive experience and specialized equipment!
We would like to introduce a research and development case of the rubber-resin cross-linked composite material 'Radicalock(R)', which was adopted for the development of the composite film for shoe soles "R-COMPO" handled by Daicel Evonik Co., Ltd. Rubber has excellent performance and functionality as a material for shoe soles, such as grip and abrasion resistance; however, a drawback of conventional technology is that rubber shoe soles tend to be heavy. To address this, we achieved a lightweight and high-performance rubber shoe sole by applying minimal rubber in a studded pattern on a thin and light resin film. The use of transparent resin has also increased the design freedom for shoe soles. In addition, we have other cases of independent research and development.

basic information
**What is Rajikarokku?** - A new bonding technology that firmly combines rubber and resin without using adhesives. - A technique that induces cross-linking reactions between the molecular chains of rubber and resin, in addition to those occurring between the molecular chains of rubber during molding. - Due to the intermolecular cross-linking bonds formed by chemical bonds (covalent bonds), the bond strength (adhesion strength) is high. *For more details, please refer to the PDF document or feel free to contact us.*
