For customers in the Tokai area: It is important to choose materials suitable for the usage environment! Please consult us if you are having trouble with rubber materials.
At our company, we select materials based on our extensive knowledge and proven track record in sales and verification. Some rubber materials can develop cracks on their surface when exposed to ozone or ultraviolet light. This occurs because, when left in the atmosphere, ozone causes a chemical reaction in the rubber, leading to molecular-level breakage. It is important to choose materials that are suitable for the usage environment of the rubber. If you are struggling with rubber material selection, please feel free to consult us. A must-see for customers in the Tokai area, especially in Shizuoka, Aichi, and Yamanashi prefectures! You can start with just a consultation.
