BN2520 é um material de revestimento de borracha de metal típico, usado principalmente na fabricação de juntas multicamadas, o revestimento de borracha é um revestimento de borracha nitrílica com excelente resistência ao óleo, e o substrato de metal é de aço inoxidável 301. Nós também chamamos este material de material de metal macio, ele poderia feito de placa de ferro fino, placa de aço inoxidável, placa de alumínio ou outra placa de metal revestida com borracha sintética. Ele combina a rigidez do metal e a elasticidade da borracha e pode ser usado como autopeças, peças de máquinas, peças de equipamentos eletrônicos e assim por diante. A temperatura máxima de operação de curto prazo para BN2520 pode até 250 °C.

Oil Resistance: NBR rubber has excellent oil resistance, which makes it suitable for use in various lubricating oil, fuel oil, and other oil-containing systems.
Abrasion Resistance: NBR rubber has good abrasion resistance, which can withstand high-speed friction and wear.
Heat Resistance: NBR rubber has good heat resistance and can withstand high temperatures up to 100°C.
Chemical Resistance: NBR rubber has good chemical resistance and can withstand most acids, alkalis, and salts.
Elasticity: NBR rubber has good elasticity and can recover its original shape after being stretched or compressed.
Electrical Insulation: NBR rubber has good electrical insulation properties and is widely used in the production of electrical components and insulation materials.
Processing properties: NBR nitrile butadiene rubber has good processing properties.
Rubber coated metal material (RCM) have a wide range of applications.
1. Automotive industry: RCM can be used to make auto parts, such as gaskets, shock absorber parts, suspension system parts, etc. Because of the good flexibility and wear resistance of metal rubber composites, it can effectively dampen and absorb the vibration caused by road bumps, improve driving comfort and stability. At the same time, metal rubber can also prevent water, dust and other external substances from entering the interior of the car, improve the sealing of the car. In addition, the processing technology of metal rubber coatings can also be extended from the bonding of rubber and metal to the bonding of rubber and plastic and fiber fabric. With the increase of the types of composite products and the expansion of the application field, the requirements for bonding technology are becoming higher and higher, and the application prospect of metal rubber coatings is broad.
2. Industrial Machinery: This material can be used for sealing components in heavy machinery that operate under harsh conditions, such as turbines, boilers, and heat exchangers.
3. Oil and Gas Industry: BN2520 can be used in the production of seals and gaskets for pipelines, valves, and other equipment that handle high-pressure and high-temperature fluids.
Please note that these are general recommendations based on the general operation conditions. The suitability of the material for a specific application should be determined through further testing and analysis.
