Product and component quality is paramount for aerospace vessels. The delivery of high-quality components contributes to the safety of those on board. Chloroprene Rubber (CR), also known as chlorobutadiene rubber, is an important diene-based elastomer. The chlorine in the polymer reduces the reactivity to many oxidizing agents and thus improves its chemical resistance. Due to its low reactivity, it displays good resistance to ozone cracking, heat aging, and chemical attack. For example, it has good resistance to many chlorofluorocarbons, aliphatic hydrocarbons, mineral oils, greases, and ozone, but only moderate or poor resistance to acids, solvents, and fuels. Its flame resistance is excellent. Chloroprene Rubber (CR) is commonly used wherever high chemical resistance is required, such as in aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications.
BS EN 2838 specifies the properties of chloroprene rubber (CR)heat resistant, hardness 70 IRHD, for aerospace applications.
BS EN 2838 on Chloroprene rubber 70 IRHD for aerospace applications is useful for:
The demand for chloroprene rubber (CR) in the aerospace industry is greater than ever. As a customer, you can benefit from chloroprene being one of the few rubbers that are self-extinguishing. It also gives excellent rubber-to-metal bonds. CR's mechanical properties are generally inferior to those of natural rubber but it has superior chemical resistance and lower gas permeability. By using Chloroprene rubber (CR) in both primary and secondary structures, it is possible to save weight and at the same time achieve mechanical peak values in terms of strength and stiffness of the components.
BS EN 2838 provides you with the specific properties of chloroprene rubber (CR)heat resistant, hardness 70 IRHD, for aerospace so that the products are suitable for the required purpose.
The guidelines in BS EN 2838 contribute towards including high-quality components for aerospace that are responsible for the smooth and safe functioning of vessels.
