CR flat washer is a type of flat washer made from Chloroprene Rubber (CR), which is also known as Neoprene. This type of rubber is known for its excellent resistance to weather, ozone, and chemicals. It can also maintain its flexibility over a wide range of temperatures, which makes it a popular choice for outdoor applications. CR flat washers are commonly used to distribute the load of a threaded fastener, such as a bolt or a screw, over a larger surface area. This helps to prevent damage to the surface of the material being fastened and also helps to prevent loosening of the fastener over time. CR flat washers come in different sizes and thicknesses to suit different applications. They are designed to be used in applications where a tight seal or a certain level of insulation is required. For example, CR flat washers may be used in electrical applications where they provide an effective seal against moisture and dust.1. Electrical applications - CR flat washers are an excellent choice for electrical applications where they provide a tight seal against moisture and dust, and also serve as insulators. 2. Plumbing applications - CR flat washers can be used in plumbing applications to seal pipes and prevent leaks or drips. 3. Automotive applications - CR flat washers are commonly used in automotive applications because of their excellent resistance to weather, ozone, and chemicals. 4. Industrial applications - CR flat washers are a popular choice for industrial applications where heavy machinery and equipment are involved. They can help distribute the load and prevent damage to the surface of the material. 5. Marine applications - CR flat washers are an excellent choice for marine applications because they are resistant to saltwater and harsh weather conditions. 6. Agricultural applications - CR flat washers are used in various agricultural machinery where they can withstand harsh environmental factors such as dust and mud. Overall, CR flat washers are a versatile and durable option for many different types of applications. Their resistance to weather, ozone, and chemicals make them suitable for use in harsh environments.
