Acrylonitrile butadiene rubber (NBR)
Synthetic rubber with exceptional lubricant behaviour which makes it a first choice for seals and O-rings. Limited resistance to weathering and acids.
Typical temperature range from -30 ºC to +110 ºC.
Fluoroelastómero (FPM / FKM)
This material is popularly known as viton. It has good resistance to lubricants, fuels, acids and bases, among other products. Peroxide cured formulations improve its resistance to incompatible fluids such as alcohols and steam. Widely used as seals and O-rings, it is noted for its low gas permeability.
Typical temperature range from -20 ºC to +210 ºC.
Cloropreno (CR)
Este material se conoce popularmente como neopreno. Tiene buena resistencia a la intemperie, a los lubricantes y al amoníaco, entre otros productos. Buena resistencia a la abrasión.
Rango de temperatura más habitual desde -40 ºC hasta +100 ºC.
