Polychloroprene’s overall physical characteristics classify it as a general-purpose elastomer.

 

CR possesses excellent aging characteristics in ozone and weather environments, along with abrasion and flex cracking resistance.

 

Polychloroprene is widely known for its: 

 

  • High compression set
  • Flex fatigue
  • Weather and ozone resistance

General Properties

Good weathering and flame resistance, moderate resistance to petroleum-based fluids 

Resistant to 

Moderate chemicals and acids, ozone, oils, fats, greases, and solvents 

Attacked by 

 Concentrated oxidizing acids, aldehydes, and esters, ketones, halogenated-, and aromatic- and nitro hydrocarbons

General Polymer Characteristics
 Abrasion Resistance  Good    Gas Permeability  Good
 Compression Set  Fair  Low Temperature Flexibility  Good
 Elongation  Good  Tear Resistance   Fair
