Description of Products for Trade Inquiry
1) Rubber materials for wetsuits: We offer a variety of chloroprene rubber/fiber composite materials depending on the application. All of them are safe and secure materials compliant with REACH and other regulations. Please contact us for details on thickness and surface specifications. We also offer some ready-made products such as immersion suits. 2) Bio Esperanza, a medical device for medical biorubber and health promotion: It gently warms the body with room temperature infrared rays without the use of electricity, supporting everyone's health.

Various chloroprene rubber/fiber composite materials are available for different applications.

The new material is also used in a variety of health promotion devices.

The new materials are stones and flowers!
Most conventional wetsuits are made primarily from petroleum. Yamamoto, on the other hand, aims for environmentally friendly and sustainable manufacturing, and produces rubber from limestone and rape blossoms at a cost of approximately 8.5 times the cost of conventional rubber. Furthermore, Yamamoto was the first company in the world to successfully recycle used wetsuits into new rubber material. Let's explore the unseen sea in a wetsuit made of stones and flowers!
