Pure PTFE fibers are sintered to improve handling characteristics and minimize fiber slough-off and downstream contamination. Recommended for filtering hot acids, strong solvents, and for applications where media contamination must be at a critically low level. Use these hydrophobic filters to separate aqueous and non-aqueous phases of mixtures as well as for air/gas filtration or venting. Temperature range is –120 to 260°C (–184 to 436°F).
