Part Number: Durlon 9400
Please provide the part number, thickness, dimensions, quantity, and process fluid. We will review material availability for the specified grade, custom cutting at our Quebec facility, or an engineered alternative tailored to your assembly.
The manufacturer's latest datasheets, certifications, and P/T curves must be reviewed prior to ordering or substitution.
Carbon-filled PTFE is compared here with graphite-filled PTFE, inorganic filler, and silicon carbide. Verify the exact service fluid. Associated reference constructions: GYLON 3530 (graphite-filled PTFE), Durlon 9000N (inorganic-filled PTFE), and top-chem 2000 (silicon carbide (SiC)-filled PTFE).
