Multiple components make up the rubber formula or recipe. The biggest component and determining factor is the base polymer. The base polymer might be Nitrile, Neoprene, EPDM or Natural Rubber for example. This determines many of the formula’s physical properties and is also the biggest cost driver within the formula.

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. Continue reading
