Discovering Viton®: A Dive into Viton 75D Black & Viton 90D Black
When it comes to high-performance sealing materials, few names stand out like Viton®. This specialized brand of Fluorocarbon (FKM), proudly bearing the trademark of The Chemours Company, has become synonymous with excellence in sealing solutions. In this blog post, we'll explore Viton®'s remarkable properties, with a particular focus on Viton 75d Black and Viton 90d Black, two of its most robust variants.
Viton 75d Black
Viton 75d Black is a specific grade of Viton® that offers a balance of properties that make it highly suitable for various demanding applications. Here are some key features and applications of Viton 75d Black:
Key Features:
- Durometer (Hardness): The "75d" in Viton 75d Black refers to its durometer rating, indicating a hardness of 75 Shore A. This level of hardness strikes a balance between flexibility and rigidity, making it suitable for applications where a moderately firm seal is required.
- Temperature Resistance: Viton 75d Black maintains its sealing properties in a broad temperature range, typically from -20°F to 400°F (-29°C to 204°C). This makes it well-suited for applications where temperature fluctuations are common.
- Chemical Resistance: Like all Viton® materials, Viton 75d Black exhibits excellent resistance to a wide range of chemicals and fluids, including hydrocarbons, acids, and fuels.
Applications:
- Aerospace: Viton 75d Black is often used in aerospace applications where it can withstand the high-temperature conditions of aircraft engines and provide dependable sealing in critical areas.
- Automotive: It's a preferred material for gaskets, O-rings, and seals in automotive systems where exposure to engine fluids, such as transmission fluids and engine oils, is common.
- Industrial: In various industrial settings, Viton 75d Black is employed for sealing applications where a balance of flexibility and firmness is required, such as in chemical processing equipment.
Viton 90d Black
Viton 90d Black, on the other hand, is a higher-durometer variant of Viton®. Its distinct properties make it suitable for applications demanding a more rigid and unyielding seal. Let's explore the key features and applications of Viton 90d Black:
Key Features:
- Durometer (Hardness): Viton 90d Black has a durometer rating of 90 Shore A, which means it's considerably harder and less flexible compared to Viton 75d. This hardness makes it ideal for applications where a firmer, less compressible seal is required.
- Temperature Resistance: This variant also offers excellent resistance to high temperatures, similar to other Viton materials. It can withstand temperatures ranging from -20°F to 400°F (-29°C to 204°C).
- Chemical Resistance: Viton 90d Black maintains its resistance to a wide range of chemicals, including aggressive solvents, fuels, and acids.
Applications:
- Oil and Gas Industry: Viton 90d Black is often used in the oil and gas industry for sealing applications, particularly in high-pressure and high-temperature environments.
- Chemical Processing: In chemical processing equipment that handles corrosive substances, Viton 90d Black is chosen for its ability to withstand harsh chemical environments.
- Automotive Racing: In high-performance automotive racing applications, Viton 90d Black is used for gaskets and seals where extreme temperatures and pressures are encountered.
