Viton is a specific type of rubber that has excellent chemical resistance, high temperature resistance, and low compression set. Viton flat washers are specially designed to withstand harsh chemicals, fuels, oils, and solvents, making them ideal for use in aerospace, automotive, and chemical processing industries. Some of the main features of Viton flat washers include: 1. Chemical resistance: Viton flat washers can resist a wide range of chemicals and solvents, including acids, alcohols, fuels, oils, and hydraulic fluids. This makes them ideal for use in harsh chemical environments. 2. High temperature resistance: Viton can withstand temperatures up to 400°F (204°C) without losing its properties, making it suitable for use in high-temperature applications. 3. Low compression set: Viton flat washers can maintain their shape and sealing properties even after being compressed for long periods, due to their low compression set. 4. Excellent sealing performance: Viton flat washers have superior sealing performance, which makes them ideal for use in critical applications where leakage is not acceptable. 5. Good mechanical properties: Viton flat washers are flexible and strong, which makes them easy to install and use in various applications. Overall, Viton flat washers are an excellent choice for applications that require high chemical resistance, high temperature resistance, and superior sealing performance.
