Neoprene

NEOPRENE

Neoprene (CR), also known as polychloroprene or chloroprene rubber, is a family of synthetic rubber produced by the polymerization of chloroprene. Neoprene is a great general-purpose rubber and for its high tensile strength, resilience, oil and flame resistance, and resistance to degradation by oxygen and ozone. The material exhibits good chemical stability and maintains flexibility over a wide range of temperatures. Neoprene is used in a wide variety of applications, making it a great option for your next sealing product application.

Recommended for industrial applications, including corrosion-resistant coatings and as a base for various adhesives.
Fire-resistant and commonly used in power transformers and other electrical applications.
A soft rubber by nature, it serves as an effective source of padding and reinforcement for certain fragile applications.

TYPES OF NEOPRENE

Commercial Neoprene

A smooth finish general purpose compound with low-temperature flexibility and oil resistance. Resists rotting, checking, and cracking caused from weather exposure.

Matte Finish Neoprene

Commercial blended sheet with a matte finish on one side. Free of talc and release solutions which make it excellent for applications involving the use of pressure sensitive adhesives.

Mid–Grade Neoprene

A smooth finish premium grade blended sheet for applications requiring a wider temperature range than standard commercial grade. This formula has great resistance to weathering and moderate resistance to oil and gasoline.

Premium Neoprene

Made with a smooth finish this product is designed to give maximum performance and service. Resistant to the degradation from ozone and good performance when in contact with oils and many chemicals, premium neoprene exhibits integrity over a wide temperature range and an outstanding resistance to damage caused by flexing and twisting.

Neoprene Performance Molded Sheets

A smooth finish high-grade formula to meet the most demanding specifications. Highly resistant to ozone degradation, weathering, and petroleum this product’s optimal use is recommended for applications that put stress and tear on components.

FDA Neoprene

This off-white Neoprene material comes with a smooth finish, untrimmed and contains FDA approved ingredients per 21 CFR 177.2600, an FDA regulation dealing with rubber articles intended for repeated food exposure.

Anti–Microbial Neoprene

Specially formulated sheet line with a smooth finish that prevents growth of bacteria, fungi, and yeasts while avoiding obstacles that organic biocides pose. This material can alleviate cleaning challenges in food-processing, medical, industrial, and other applications prone to microbial growth.

AASHTO Unsupported Calendered Neoprene Bearing Pads

Specifically designed with one or multiple layers of elastomers with a smooth finish, this neoprene is AASHTO approved and highly resilient to oxygen degradation and weathering. This material offers excellent compressive strength to handle applications from bridges to railways and is immune to UV and ozone degradation while offering excellent absorption rates for infrastructure, shock and vibration isolation, construction and steel reinforced concrete.

PROPERTIES

Denver Rubber Company neoprene works well in conjunction with a multitude of other materials allowing it to be manipulated to bond mechanically with cotton and several types of metal such as; stainless steel, aluminum, brass, and copper. With specific additives, adhesion can be induced between neoprene and materials such as glass and acrylic allowing it to be a versatile material.
