Problems solved by technology

In the process of practical application, the EPDM rubber hose will be in contact with cooling water, hot air, etc. After a long period of use, it will often age, causing the EPDM rubber hose to degrade or harden, or even crack, thus Lose its strength and other properties; in addition, as a polymer material, EPDM rubber has poor flame retardancy, and the flame retardancy of hoses made of it is not ideal
