NATURAL RUBBER (NR) Natural Polyisoprene
Advantages:
Outstanding resilience; high tensile strength; superior resistance to
tear and abrasion; excellent rebound elasticity; good flexibility at low
temperatures; excellent adhesion to fabric and metals.
Limitations: Poor resistance to heat, ozone, and sunlight; very little resistance to oil, gasoline, and hydrocarbon solvents.
Comment:
Natural rubber is a low cost material with excellent physical
properties. Generally speaking, it is ideal for applications that
require good resistance to abrasion, gouging, and cut growth. It is
tough and long wearing and can be compounded for service at temperatures
as low as -65F.
