Neoprene (CR) occupies a useful position between natural rubber and more specialised elastomers. Rather than being optimised for a single property, it offers a balanced combination of environmental durability, mechanical strength and moderate chemical resistance, making it a reliable choice for a wide range of industrial sealing applications.
Its resistance to ozone, UV radiation and moisture means neoprene retains its physical properties in environments where natural rubber would deteriorate. As a result, it is widely used in outdoor equipment, marine systems, HVAC installations and industrial machinery exposed to changing weather conditions.

A cost-effective sealing solution covering a wide range of applications across different industries, including HVAC, automotive, marine, construction, and electrical enclosures.
High-Grade Neoprene gaskets deliver exceptional performance in demanding situations and are formulated to withstand rigorous mechanical, chemical and environmental wear.
Made with EC and FDA-approved rubber material, these oil, water and temperature-resistant gaskets are the perfect sealing solution for food processing, food packaging and refrigeration seals.
Designed to resist fire, maintain its integrity at extreme heat, and prevent the buildup of static, Fire Retardant Anti-Static (FRAS) Neoprene Gaskets provide reassurance where there is a risk of explosion.
Unlike Nitrile rubber, which is primarily selected for resistance to petroleum oils, neoprene performs well where sealing components are exposed to water, weathering and intermittent contact with oils or greases. This versatility often makes it the preferred material for general-purpose engineering gaskets where multiple operating conditions must be considered. Actual performance depends on compound formulation and operating conditions.

Neoprene performs well with:
It is generally not recommended for prolonged exposure to:
Material compatibility should always be assessed alongside operating temperature and pressure.
Our highly experienced technicians can advise you on the best sheet materials and manufacturing processes for a wide range of gasket applications.
The term neoprene covers a range of compounds with differing hardness, mechanical properties and chemical performance. Selecting the correct grade involves more than simply specifying the material name.
Factors that influence gasket performance include:
By considering these factors at the specification stage, engineers can maximise gasket life and minimise the risk of premature sealing failure. Dobson Gaskets provides technical guidance alongside precision manufacturing to ensure each neoprene gasket is matched to its intended application.
