Neoprene Molding

The Custom Neoprene Molding Experts

Chemical Designation: Chloroprene (CR)

Molded neoprene rubber is a versatile and resilient polymer/elastomer, renowned for its resistance to chemical corrosion. Neoprene molding produces materials that demonstrate excellent resilience, tear resistance, and tensile strength. Additionally, neoprene is abrasion-resistant and exhibits admirable compression set properties.

Although Neoprene molded rubber is resistant to oil, gasoline, sunlight, the ozone and oxidation, other polymers have better resistance to these same elements

What is Neoprene Rubber?

Molded neoprene rubber is a highly versatile and durable elastomer, celebrated for its exceptional resistance to chemical corrosion. The neoprene injection molding process produces materials with outstanding resilience, tear resistance, and tensile strength. Neoprene also offers superior abrasion resistance and excellent compression set properties, making it an ideal choice for a wide range of applications demanding reliable performance and durability.

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.
