A75H

A75H is a high performance elastomer formulated using Aflas® FA- 100H FEPM for the demanding sealing applications experienced in the upstream oil and gas industry.

A75H exhibits high temperature thermal stability with broad fluid resistance.

A75H provides excellent resistance to acids, steam, hot water, brine, oils, lubricants and sour oil/gas (H2S) and most fluids found in oil and gas drilling and completion operations. It is resistant to all types of hydraulic fluids (including alkyl-aryl phosphate esters), all brake fluids (glycol, mineral and silicone base), amine corrosion inhibitors and additive packages.
