Cloropreno (CR)
This material is popularly known as neoprene. It has good resistance to weathering, lubricants and ammonia, among other products. Good resistance to abrasion.
Most common temperature range from -40 ºC to +100 ºC.
Silicone (VMQ)
Methyl vinyl silicone rubber with outstanding thermal resistance and good cold flexibility. Good electrical properties. In general, its chemical resistance is poor. It is usually used in cryogenics.
Most common temperature range from -60 ºC to +250 ºC.
Fluoroelastómero (FPM / FKM)
This material is popularly known as viton. It has good resistance to lubricants, fuels and acids and bases, among other products. Peroxide-cured formulations improve its resistance to incompatible fluids such as alcohols and steam. It is a material widely used as seals and O-rings that stands out for its low permeability to gases.
Most common temperature range from -20 ºC to +210 ºC.
