Material of food-grade rubber hose

In general, the inner and outer rubber layers of ordinary rubber hoses are made of natural rubber, SBR or BR. For hoses that need to be oil-resistant, CR and NBR are ideal. For hoses that need to be acid, alkali and high temperature resistant, EPDM, FKM, silicone rubber as well as EPDM rubber are better. These materials have good heat, chemical corrosion and aging resistance. Thus they can work for a long time in high temp and high pH environments.
