Engineered for extremes
FEPM ESP 80P
Read the code: FEPM, ESP duty (electric submersible pumps), 80 Shore A, P for peroxide cure, recipe 01.
Development grade. The values below are design targets, not measured results. Each target becomes a typical value, with the number of lots and the test report behind it, as testing is completed.
An 80 Shore A FEPM for electric submersible pump protector bags, bonded parts and diaphragms: flex-fatigue resistance with FEPM resistance to H2S, amines, brines and hot oil.

Qualification plan
The grade code says what this compound is designed for. This table says what it has passed: a duty is claimed only once its report is on file.
| Test | Standard or method | Conditions | Status |
|---|---|---|---|
| Flex fatigue | ISO 132 (DeMattia) | Before and after hot sour ageing | Planned |
| Hot sour fluid ageing | ISO 23936-2 Annex A | Sour multiphase fluid | Planned |
| Bag qualification | ESP OEM test | On the OEM's protector design | Planned |
Design targets are the values the compound is designed to reach. They are not measured results and they are not a warranty. Release limits apply to lots once the recipe is approved. The grade code says what the compound is designed for; the qualification plan says what it has passed. Confirm suitability in your own application and fluids.
