Industrial Elastomer Selection Guide
Correct industrial elastomer selection is critical for the service life of components such as seals, gaskets, o-rings, drive belts, and flooring. Each material has a unique profile of chemical, thermal, and mechanical resistance that must match the operating conditions.
The main industrial elastomers include SBR (general-purpose synthetic rubber), Neoprene CR (weather resistance), Nitrile NBR (oil resistance), EPDM (steam and water resistance), Silicone VMQ (high temperature and food-grade), Polyurethane PU (maximum abrasion resistance), Viton® FKM (extreme chemical resistance), and Natural Rubber NR (maximum elasticity and vibration damping).
The ASTM D2000 classification organizes elastomers by temperature range (grade) and oil resistance (type). This standard is the reference in B2B industrial supply engineering specifications across Mexico and Latin America.
