Sealmtl's high-performance sealing materials are widely used in key industrial fields. FFKM O Rings and AFLAS rubber apply to semiconductor, chemical and aerospace fields for corrosion and high-temperature resistance. Molded and impregnated graphite are for low-pressure valves and pump seals. SSIC-based, modified SiC and coated seals (DLC, CVD, tungsten carbide) suit high-speed, high-precision and extreme corrosion conditions. Chromium oxide sleeves, wave springs and lightweight tungsten carbide serve bearing parts, mechanical seals and high-speed lightweight equipment respectively.
