Properties and Applications of Neoprene Sealing Materials

09 April 2021

Sealing materials such as gaskets can be very useful in filling up the space between the surfaces of two or more joined components. Once gaskets are installed, fluid and other elements are ensured to not escape or enter the assembly anymore. The assembly, with the integration of reliable and high-quality gaskets, can remain intact throughout its operations and service life.

There are a lot of materials available in producing and manufacturing sealing materials. One of the materials is neoprene. Neoprene is a type of synthetic rubber that is manufactured through the polymerisation of chloroprene. Generally, this specific material has good chemical stability, making it very useful for manufacturing cable jackets, tubing, gasoline hoses, and other similar products.

Properties of Neoprene Sealing Materials

Neoprene sealing materials boast a lot of notable properties.

One of the known properties of neoprene sealing materials is that they are elastic. The elastic property of neoprene sealing materials allows it to stretch and fit comfortably to different materials. They can even conform to a wide array of sizes and shapes, making them very useful in flexible applications. Aside from their elastic property, neoprene sealing materials also have a cushioning property. This property alone enables them to absorb shock and vibration.

Another property of neoprene sealing materials is that they have high tensile strength. Neoprene materials themselves typically have a tensile strength of 900 to 1,000 PSI. And once they are mixed with other materials, they can effectively resist damaging elements such as abrasion, chemicals, combustion, grease, oil, oxidation, sunlight, temperature, weather, and water.

Neoprene sealing materials can withstand extreme temperatures. Their elongation can even range from 350% to 400%, while their hardness ratings ranging between 40 and 80. Lastly, neoprene sealing materials are impermeable, which can prevent the escape and entry of liquids and even gases from and to the involved surfaces of an assembly.

Applications of Neoprene Sealing Materials

Given the properties of neoprene gaskets, industries such as aerospace, automotive, electronics, lighting, HVAC, and medical all utilise them as their main sealing material. Neoprene can be utilised by these industries either for static or dynamic sealing. Static sealing involves the installation of gaskets in stationary applications, while dynamic sealing entails the installation of the gaskets between moving and stationary surfaces. The use of neoprene sealing materials in dynamic sealing can help retain or separate fluids, prevent ingress of particles, and effectively contain pressure.

Some of the most notable applications of neoprene sealing materials include pump impellers, hydraulic systems, doors, and windows.
