Chloroprene Rubber is moderately resistant to both petroleum oils and weather (ozone, UV, oxygen). This qualifies Chloroprene uniquely for certain sealing applications where many other materials would not be satisfactory. Chloroprene has relatively low compression set, good resilience and abrasion, and is flex cracking resistant. Chloroprene 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.
