PFA Gasket Manufacturing & Distribution
At McDowell & Company, we specialize in manufacturing PFA (Perfluoroalkoxy) gaskets, the ultimate choice for critical sealing applications where exceptional purity and chemical resistance are non-negotiable. As one of the most advanced fluoropolymers available, PFA combines the best properties of PTFE with enhanced mechanical strength and superior melt processability. When your systems require maximum chemical resistance, highest purity standards, and excellent high-temperature performance, partnering with an experienced PFA gasket manufacturer is essential for success.

Frequently Asked Questions (FAQs)
1. What distinguishes PFA gaskets from other fluoropolymer options?
PFA gaskets provide superior mechanical strength compared to PTFE, better high-temperature performance than FEP, and exceptional purity levels. They maintain their properties even after repeated high-temperature exposure.
2. What are the key benefits of PFA for high-purity applications?
PFA offers extremely low extractables, excellent chemical resistance, superior mechanical properties, and maintains its integrity in high-temperature environments. It’s ideal for semiconductor and pharmaceutical applications requiring the highest purity standards.
3. How do PFA gaskets perform in extreme temperatures?
PFA gaskets maintain their properties from cryogenic temperatures (-320°F) up to 500°F continuous service, with excellent creep resistance and mechanical stability throughout this range.
4. What clean room capabilities do you offer for PFA gaskets?
We manufacture PFA gaskets in Class 100 clean room conditions with full particle control, clean packaging protocols, and comprehensive documentation for high-purity applications.
5. Can you provide validation for high-purity applications?
Yes, we offer complete validation packages including TOC analysis, metal ion testing, extractables studies, and particle testing to meet semiconductor and pharmaceutical industry requirements.
