Features of Low Temperature Viton™
- Chemical Resistance: Exceptional resistance to oils, fuels, lubricants, and most mineral acids, making it ideal for harsh chemical environments.
- Thermal Range: Although primarily known for high temperature resistance, low temperature Viton™ maintains good mechanical properties at significantly lower temperatures than standard FKM materials.
- Durability: Known for its durability and longevity, reducing the need for frequent replacements of O-rings, gaskets, and custom parts.
- Versatility: Suitable for a wide range of applications due to its strength and chemical compatibility.
Limitations of Low Temperature Viton™
- Cost: More expensive than many other elastomers, due to its specialized properties and performance advantages.
- Limited Flexibility: While improved, low temperature Viton™ is still less flexible than some other low temperature elastomers like silicone or PVMQ.
- Color and Appearance: Typically available in fewer colors and finishes, which may be a consideration in applications where aesthetics are important.
