In 2010, as the first peroxide-cured FKM batch reacted in Jiangsu kettles, CHM mutated the DNA of sealing history. 14 years of forging, 5,000 formulation evolutions, 9,600 MT compounds across 30 nations — from Tesla battery seals to Crew Dragon hatches, TSMC EUV chambers to Chevron’s 10,000-meter wellheads. Today, CHM FluoroPlus® fluorine atoms resonate at every critical juncture of human industry: Where temperature, corrosion, and pressure reign — there lies our sealed domain!
