PTFE Diaphragms
PTFE Diaphragms – Precision, Purity & Performance
Polytetrafluoroethylene (PTFE) is a high-performance fluoropolymer known for its exceptional chemical inertness, thermal stability, and low-friction surface. Its unique molecular structure makes it one of the most reliable materials for applications involving aggressive media, extreme temperatures, and demanding process environments.
When molded into a diaphragm, PTFE offers superior durability and resistance compared to conventional elastomers. It withstands corrosive acids, solvents, high-purity fluids, and wide temperature variations without degradation, making PTFE diaphragms the preferred choice for critical processing industries.
At Arvico, we engineer PTFE diaphragms to deliver long-lasting, leak-proof performance in demanding pumping and dosing systems. Each diaphragm is rigorously tested to endure up to 5 million cycles, ensuring extended service life with minimal maintenance and maximum reliability.
