Neoprene homopolymer of chlorobutadiene and is unusual in that it is moderately resistant to both petroleum oils and weather (ozone, UV, oxygen). This qualifies neoprene uniquely for certain sealing applications where many other materials would not be satisfactory. Neoprene is classified as a general purpose elastomer which has relatively low compression set, good resilience and abrasion, and is flex cracking resistant. Neoprene has excellent adhesion qualities to metals for rubber to metal bonding applications. It is used extensively for sealing refrigeration fluids due to its excellence resistance to Freon® and ammonia.

Primary Uses

O-rings, rubber seals and custom moulded rubber components for:

refrigeration industry applications

general purpose seals, hose and wire

Application Advantages

petroleum fuel and oil resistance

resists flex cracking

good ozone resistance

good heat resistance

Application Disadvantages

poor compression set performance relative to NBR

lesser water resistance and low temperature performance than some other elastomers
