Here’s Why You Need to Think Beyond Conventional FKMs


The oil and gas industry uses drilling equipment to bear high pressure and high-temperature muds coming out of the well. Drilling mud and other fluids contain many chemicals that can attack O-rings and packer seals. Daikin Chemicals has successfully developed a base resistant elastomer (DAI-EL-BRE) containing 62% fluorinated polymers. The material is FKM type-6 classified under ASTM D1418, with an advantage over conventional FKMs of showing excellent resistance towards fuels, acids, amines, coolant fluids, and mud fluids. The DAI-EL-BRE material can be very useful in manufacturing O-rings and Packer seals with excellent amine resistance, drilling mud resistance and heat resistance.
