Natural rubber is a polymer that is derived from the latex sap of certain types of plants, primarily the rubber tree (Hevea brasiliensis). It is a resilient and elastic material known for its unique properties, such as flexibility, high tensile strength, and excellent resilience to deformation.
The following table provides a comprehensive list of natural rubber (NR) properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
