[Research and Development Case] Rubber × Resin Cross-linked Composite Material 'Radicalock'
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 "R-COMPO" for shoe soles handled by Daicel-Evonik Co., Ltd. Rubber has excellent performance and functionality as a material for shoe soles, such as grip and abrasion resistance, but the conventional technology had the drawback of making rubber shoe soles heavy. To address this, we achieved a lightweight and high-performance rubber shoe sole by applying minimal rubber in a stud-like pattern on a thin and light resin film. By using transparent resin, we increased the design freedom for the shoe sole. In addition, we also have examples of independent research and development. 【Research and Development Cases】 ■ Inter-company collaborative development ■ Independent research and development *For more details, please refer to the PDF document or feel free to contact us.

basic information
**What is Rajikarokku?** - A new adhesive technology that firmly bonds rubber and resin without using adhesives. - By inducing cross-linking reactions that occur between rubber molecular chains during the molding of rubber, this technology also generates cross-linking reactions between the molecular chains of rubber and resin, allowing for direct chemical bonding between them. - Due to the intermolecular cross-linking bonds created by chemical bonding (covalent bonds), the bond strength (adhesion strength) is high. *For more details, please refer to the PDF document or feel free to contact us.*
