Features of Viton™ ETP
- Exceptional Chemical Resistance: Viton™ ETP is specifically engineered to resist a wider range of fluids and chemicals, including bases, amines, and organic solvents, which typically degrade other fluoroelastomers.
- High Temperature Performance: Maintains integrity in high thermal environments, making it ideal for high-stress applications.
- Longevity: Offers excellent durability, often surpassing that of other elastomers in tough chemical exposures, which minimizes downtime due to component failure in industrial settings.
- Versatility: Suitable for manufacturing various components such as O-rings, gaskets, and custom parts, especially where standard FKM materials fail.
Limitations of Viton™ ETP
- Cost: As a high-performance material, Viton™ ETP comes at a higher cost, reflecting its advanced resistance capabilities and production complexity.
- Processing Challenges: The material requires careful handling and processing during manufacturing to ensure the properties are maintained.
- Limited Flexibility at Low Temperatures: While excellent in high and ambient temperature ranges, it may not perform as well in extremely low temperatures compared to specialized low-temperature materials.
