BF2520 es un material de revestimiento de caucho metálico típico, que se utiliza principalmente para la fabricación de juntas de culata multicapa. El revestimiento de goma es un revestimiento de caucho de flúor resistente a altas temperaturas, y el núcleo de metal es 301 de acero inoxidable. El espesor total del material es de 0,25mm. También llamamos a este material de metal blando, que está hecho de placa de hierro delgada, placa de acero inoxidable, placa de aluminio u otra placa de metal recubierta con caucho sintético en su superficie. Combina la rigidez del metal y la elasticidad del caucho. Puede ser utilizado para hacer piezas automotrices, piezas de máquinas, piezas de equipos electrónicos. Y puede ser utilizado como aislamiento acústico y materiales de prevención de vibraciones. La temperatura máxima de operación a corto plazo para BF2520 podría alcanzar hasta 250 ℃.

Applications of BF2520 Rubber Coated Metal Material (RCM)

Applications of BF2520 Rubber Coated Metal Material(RCM)

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: BF2520 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. Always consult with Teamful Sealing materials engineer for advice tailored to your specific needs.
