What should we know about NR (Natural rubber) hoses?

Natural rubber (NR) hoses are, as their name suggests, made of rubber material obtained from the natural latex sap of rubber trees. When we examine a natural rubber sample, approximately 94% of it is made up of polyisoprene, while the remaining few percent is made up of natural resin, protein, and small amounts of water and ash. The combination of resin, protein and polyisoprene with a high cis content gives the unique properties of natural rubber hoses, which are used in many industries, because they have a high resistance to inorganic chemicals.
