Neoprene Rubber & Sponge


Chloroprene Rubber (CR), widely known as Neoprene®, was one of the first oil-resistant synthetic rubbers.  Neoprene 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.  

Die-Cut Products stocks a broad spectrum of sponges & rubbers for your custom fabrication needs.  This includes both solid rubbers as well as open-cell and closed-cell sponge rubbers.  All materials are available with full cure date, shelf life, and supplier test reports right from the mill.   Need RoHS-compliant material?  We offer that too!

Benefits of Neoprene Rubber & Sponge

Neoprene rubber & sponge are considered to be a good general-purpose rubber with an excellent balance of physical and chemical properties. It has better chemical, oil, ozone and heat resistance than natural rubber but a rather lower level of physical properties. Chloroprene tends to slowly absorb water and its electrical properties are poor. Its gas permeability is fairly low and flame resistance is excellent, chloroprene being one of the few rubbers that are self-extinguishing. 

Neoprene has excellent adhesion qualities to metals for rubber-to-metal bonding applications.  It is used extensively for sealing refrigeration fluids due to its excellent resistance to Freon® and ammonia.

Typical temperature range for Neoprene is -40°F to +250 °F
