The Custom Neoprene Molding Experts
Chemical Designation: Chloroprene (CR)
Molded neoprene rubber is an all-purpose resilient polymer/elastomer because it provides resistance to corrosion from chemicals. Neoprene demonstrates resilience, tear resistance and tensile strength. Additionally, it is abrasion resistant and has admirable compression set properties.
Although Neoprene is resistant to oil, gasoline, sunlight, the ozone and oxidation, other polymers have better resistance to these same elements.

What is Neoprene Rubber?
Neoprene Rubber or Polychloroprene (CR) is a versatile synthetic rubber with exceptional resistance to oil, petroleum and weathering. It also offers good UV, ozone and chemical stability; flexibility over a wide temperature range and superior abrasion resistance. Neoprene is often found in laptop sleeves, electrical insulation, automotive fan belts and various other industries and applications.
Neoprene production involves free-radical polymerization of chloroprene. In commercial production, however, it is prepared by free radical emulsion polymerization. Chloroprene polymerization is initiated with potassium persulfate. Bifunctional nucleophiles, metal oxides and thioureas are then used to cross-link individual polymer strands.
Although natural rubber offers better mechanical properties, Neoprene’s resistance to degradation is far better than both natural and synthetic rubber. As a result, it is ideal for particularly demanding applications: gaskets, hoses, tubing, corrosion-resistant coatings.
