Fluoroelastomer Specialists
As described in Chemical Book’s article, “The Different Types of Fluoroelastomers,” Viton™ fluoroelastomers are known for their exceptional resistance to chemicals, high temperatures, and oxidation. These materials are utilized in demanding applications, including automotive, industrial, and chemical processing, due to their unique composition and adaptability.
Viton™ fluoroelastomers are classified into three main families—A, B, and F—along with specialized high-performance grades like GB, GBL, GLT, and GFLT, each offering specific properties:
- Viton™ A: A general-purpose fluoroelastomer for O-rings, gaskets, and molded shapes. It’s composed of vinylidene fluoride and hexafluoropropylene, ideal for basic sealing needs.
- Viton™ B: Comprising three monomers, Viton™ B provides better fluid resistance, suited for applications involving aggressive lubricants and oxygenated fuels.
- Viton™ F: The most fluid-resistant grade, Viton™ F excels in environments with high fuel permeation, making it ideal for fuel handling systems.
High-Performance Grades:
- Viton™ GBL: Uses peroxide cure chemistry, offering enhanced resistance to steam, acid, and aggressive oils, making it valuable for engine components.
- Viton™ GLT: Retains high heat resistance while enhancing low-temperature flexibility, with a glass transition temperature 8–12°C lower than standard Viton™ grades.
- Viton™ GFLT: Combines superior chemical resistance with improved low-temperature performance, ideal for applications needing extreme durability in both hot and cold conditions.
These diverse grades of Viton™ allow manufacturers to tailor fluoroelastomer selections based on specific chemical exposure and temperature requirements.
