We offer a range of closed-cell chloroprene cellular rubber products that are ideal for sealing against water, air and, to a certain extent, oil. Its closed-cell structure makes it resistant to moisture and water. Chloroprene cellular rubber is a high-quality, all-round solution that can be used, for example, for gaskets, sealing strips, vibration damping and insulation across a wide range of industries.
CR stands for chloroprene and is a type of synthetic rubber often known by the trade name neoprene. In its cellular form, chloroprene rubber combines its all-round properties – good weather and ozone resistance, moderate resistance to oils and fats, and good mechanical strength – with a closed-cell, compressible structure. This makes CR cellular rubber a versatile choice when you need to seal against dust, moisture, air or water, even at low installation pressure. CR cellular rubber is available in several formats, including strips, sheets and rolls, as well as die-cut components, often with a self-adhesive backing for easy installation.
The closed-cell structure prevents the material from absorbing liquid, ensuring an effective and reliable seal over time. CR cellular rubber also offers good resistance to weathering, ozone and ageing, good flame resistance and high wear resistance. The material also has good elasticity and resilience, enabling it to retain its sealing function even under repeated compression and mechanical stress.
Wide range of applications for CR cell rubber
CR cellular rubber is used across many industries thanks to its balanced properties. In the automotive industry, it is used for seals, gaskets and vibration-damping components. In the construction and ventilation sectors, it is a common choice for sealing strips, flange gaskets and condensation insulation. The material is also used in the marine and offshore industries due to its good resistance to salt water and weathering – neoprene, for example, is the classic material used in wetsuits. CR cellular rubber is also common in the engineering industry, where a single gasket needs to withstand weather, oil and mechanical stress.
Die-cut parts and mouldings made from CR cellular rubber
Die-cut components made from chloroprene cellular rubber are a popular solution when you need a versatile seal that can withstand mixed environments. Similarly, CR cellular rubber strips are easy to cut and customise for sealing doors, hatches and joints. Thanks to its good resistance to ozone, weather, ageing and moderate oil exposure, CR cellular rubber is a reliable all-round choice – where pure oil resistance is required, NBR cellular rubber is a better alternative; for extreme temperatures or high purity requirements, silicone cellular rubber is suitable; whilst EPDM cellular rubber is the first choice in clean outdoor environments. If you’re unsure which material is suitable for your application, we’ll be happy to help you find the right one.
