A90H is a high performance, explosive decompression resistant, elastomer formulated using Aflas ® FA-100H for the demanding sealing applications experienced in the oil and gas exploration and extraction industry.

A90H exhibits similar thermal stability to fluoroelastomer (FKM) grades but offers a different chemical resistance profile.

A90H provides particularly high resistance to acids, amines, steam, brine, sour oil and gas (H2S).

Key Attributes

Excellent resistance to Explosive Decompression

Tested to NACE TN0297

Resistant to high pressure CO 2 gas

Ideal for prolonged exposure to steam

Short-term high temperature capability up to 290°C (554°F)

Excellent resistance to fluids with high H 2 S concentration

Typical Applications

High temperature pumps

Safety valves

Logging equipment

Completion and production equipment
