Neoprene - Neoprene Rubber

Trade Names:

• Neoprene (formerly) - E.I. du Pont de Nemours Company
• Butaclor - Distugil
• Petro-Texneoprene - Petro-Tex Chemical Company

Neoprenes are homopolymers of chloroprene (chlorobutadiene) and were among the earliest of the synthetic rubbers available to the seal manufacturers.

Neoprene can be compounded for service at temperatures of -65 degrees +300 degrees F (-54 to +149 degrees C). Most elastomers are either resistant to deterioration from exposure to petroleum lubricants or oxygen. Neoprene is unusual in having limited resistance to both. This, combined with broad temperature range and moderate cost accounts for its desirability in many seal applications.

Chloroprene is recommended for:

• Refrigerants (Freons, ammonia)
• High aniline point petroleum oils
• Mild acid resistance
• Silicate ester lubricants

Chloroprene is not recommended for:

• Phosphate ester fluids
• Ketones (MEK, acetone)
