Neoprene
One of the earliest of the synthetic materials to be developed as
an oilresistant substitute for Natural Rubber, Neoprene is a homopolymer
of chloroprene (chlorobutadiene).
Temperature Range: Standard Compound: 45 ºF to +250ºF. (Dry
Heat Only)
Hardness (Shore A): 40 to 90.
Features: Neoprene can be used in innumerable sealing applications,
due to its broad base of such desirable working properties as: moderate
resistance to petroleum oils; good resistance to ozone, sunlight and
oxygen aging; relatively low compression set; good resilience; and
reasonable production cost.
Due to its excellent resistance to Freonl~l and Ammonia, Neoprene
is also widely accepted as a preferred material for refrigeration
seals.
Limitations: Neoprene is generally attacked by strong oxidizing acids;
esters; ketones; chlorinated, aromatic and nitro hydrocarbons.
Because Nitrile is economically competitive with Neoprene, and generally
has superior performance characteristics in most situations, it has
largely replaced Neoprene in the Orings of today.
