Chlorine dioxide is a powerful disinfectant widely used across various industrial applications, including pulp bleaching, chemical processing, food processing, pharmaceutical production, and water treatment. Despite its effectiveness, chlorine dioxide is a hazardous chemical that poses significant risks. Exposure can lead to respiratory issues, skin irritation, and eye damage. It is also highly flammable and reactive, presenting further fire and explosion hazards. As such, a reliable fluid containment solution with chemically compatible gaskets is essential.
To ensure safety and maintain efficiency, it is crucial to use gaskets specifically designed for compatibility with chlorine dioxide. Opting for chemically incompatible or low-cost materials can lead to failures, safety hazards, and inefficiencies in operations. Therefore, we recommend using high-quality, durable gaskets that offer proven chemical resistance.
Recommended Gasket Materials for Chlorine Dioxide
Our team at Gasket Resources Inc. (GRI) has over 20 years of experience in designing and manufacturing fluid sealing systems tailored for chlorine dioxide applications. We recommend the following materials for gaskets in environments involving chlorine dioxide:
- Durlon® 9000: This engineered PTFE gasket is formulated for use with highly aggressive chemicals, including chlorine dioxide. Made by blending inorganic fillers with pure PTFE resin, Durlon® 9000 offers superior chemical resistance and is FDA approved, making it suitable for various demanding industrial settings.
- Durlon® 9200: Similar to Durlon® 9000, Durlon® 9200 is a barium sulfate-filled PTFE gasket. Its filler system is evenly dispersed, avoiding the voids and buildups often seen in layered PTFE materials. This even distribution provides consistent physical and mechanical properties, and it is resistant to cold flow and hardness issues.
- Durlon® 9600: Composed of 100% pure expanded PTFE, Durlon® 9600 offers enhanced mechanical strength without compromising chemical resistance. It is particularly suited for chlorine dioxide applications, as it resists cold flow and hardness degradation.
- Genuine Viton® B: Viton® B is a fluoropolymer elastomer synthetic rubber made from a blend of vinylidene fluoride, hexafluoropropylene, and tetrafluoroethylene. This material provides excellent chemical resistance and is ideal for applications that require high elasticity and mechanical strength.
- Viton® GF-S: An advanced Viton® material, Viton® GF-S is a high-fluorine polymer manufactured using Chemours Performance Elastomer Advanced Polymer Architecture (APA) technology. It offers superior chemical resistance and optimal mechanical properties, making it ideal for applications involving chlorine dioxide.
