Natural Rubber (NR) Gum. As the name would indicate, this elastomer occurs naturally and comes from the latex of certain trees and plants. After the latex is processed, it becomes an elastomer with excellent mechanical properties.It has excellent tensile, elongation, tear resistance and resilience.tyrene Butadiene (SBR) (Buna-S) (GRS). This is a copolymer of styrene and butadiene. It has similar properties to natural rubber. Its resistance to solvents and petroleum products is about the same as natural rubber.
