FAQ
1. What are the key benefits of using PFA linings?
PFA linings provide exceptional chemical resistance, high-temperature tolerance, and a smooth, non-stick surface that protects equipment from corrosion and chemical attack. They also extend the lifespan of equipment by reducing maintenance needs.
2. What industries typically use PFA-lined equipment?
PFA linings are used across a variety of industries, including:
- Chemical processing (storage tanks, pipes, and valves)
- Pharmaceutical and food processing (tanks and containers for high-purity applications)
- Electronics and semiconductor (components that require high purity and chemical resistance)
3. How do PFA linings compare to PTFE linings?
Both PFA and PTFE offer excellent chemical resistance and non-stick properties. However, PFA has better mechanical strength and flexibility, which makes it a preferred choice for linings requiring a uniform, thicker layer.
4. What thickness options are available for PFA linings?
Standard thicknesses range from 1.5 mm to 5 mm, although custom thicknesses may be available depending on your specific application requirements.
5. Are PFA linings suitable for high-temperature applications?
Yes, PFA linings can continuously operate at temperatures up to 260°C and can withstand short-term exposure to temperatures as high as 300°C.
6. Are PFA linings FDA-approved for food applications?
Yes, high-quality PFA linings are FDA-compliant, making them suitable for applications that involve food contact, such as in the food and beverage industry.
7. Can PFA linings be used for outdoor applications?
Yes, PFA linings provide excellent resistance to UV radiation, weathering, and environmental exposure, making them suitable for outdoor use.
8. How should PFA-lined equipment be cleaned and maintained?
PFA linings are easy to clean due to their non-stick surface. Standard cleaning methods, such as using mild detergents and soft brushes, are recommended. Avoid abrasive tools that could damage the lining.
