Next-generation environment-friendly automotive air-conditioning hose
Yokohama Rubber is now developing a next-generation environment-friendly automotive air-conditioning hose using a rubber-resin polymer alloy. This alloy has a sea-island structure that realizes high gas barrier properties while maintaining the flexibility and heat resistance of rubber. As a result, we succeeded in making the hose thinner and achieved a significant weight reduction of 50% compared to conventional hoses.
Yokohama Rubber’s wide variety of structural designs for hoses, advanced assembly technologies, and product evaluation techniques enables us to provide hose products that meet diverse customer needs.
We welcome all inquiries from OEMs, Tier-1 suppliers, resin component suppliers, and raw material suppliers, and others interested in our new technology. Please click the below link to send an inquiry. One of our dedicated company engineers will respond as quickly as possible.

Structure of new rubber-resin polymer alloy
By making our new rubber-resin polymer alloy a sea-island structure, it provides high gas barrier properties while maintaining the flexibility and heat resistance of rubber. Conventional rubber is generally made thicker to ensure gas barrier properties, but this increases the weight of the hose. The high gas barrier performance of the newly developed polymer alloy’s resin phase allows us to reduce the thickness and reduce the weight of the hose.
Challenge to develop resin piping
Aiming to use resin in almost all parts of the pipe system
Applying diverse technologies to achieve pipe resinization
Seeking partners for joint development effort
AC Pipe System
We provide innovative solutions
Yokohama Rubber’s wide variety of structural designs for hoses, advanced assembly technologies, and product evaluation enables us to meet diverse customer needs.
We believe that this new high polymer material can be applied to other applications such as battery cooling lines, as well as to other areas, such as hydraulic equipment and aerospace products.
We are also considering applying this new technology to other routing improvements.
