Product Overview
CH-F401C fluororubber (FKM) is a high-performance elastomer formulated with DuPont raw rubber. Fluorine atoms in the polymer chains provide exceptional protection for carbon-carbon bonds, ensuring chemical stability, mechanical strength, and long-term reliability for demanding industrial applications.
Key Features
· High-Temperature Resistance: Operating range from -15℃ to 260℃; decomposition temperature exceeds 400℃
· Oil & Chemical Resistance: Resistant to fuels, hydraulic fluids, lubricants, acids, and alkalis
· Aging & Weather Resistance: Excellent resistance to UV, ozone, and atmospheric aging
· Mechanical Performance: Low permanent compression set for long-term sealing reliability
· Superior Gas Tightness: Achieves vacuum levels from 1.33×10^-7 to 1.33×10^-8 Pa
Typical Applications
· Aerospace sealing components
· Oil drilling and drilling equipment
· Petrochemical pipelines and equipment
· Compressors, engine valve stem seals, cylinder seals, clutch seals, fuel pump seals
· O-rings, gaskets, and custom rubber sealing solutions
