Engineered for extremes
NBR Swell 60S
Read the code: NBR, SWELL duty (swellable elements), 60 Shore A, S for sulfur 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.
A 60 Shore A nitrile compound containing a superabsorbent polymer, for water-swell packers and seals in water-producing zones up to about 120 °C. Swelling is fastest in fresh water and slows as salinity rises.

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 |
|---|---|---|---|
| Swell rate in brines | In-house method, published with results | Customer brine at well temperature | Planned |
| Pressure holding | In-house fixture | After swelling | 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.
Every lot is supplied with a certificate of analysis. Enter the lot ID under Track on the website to see the lot record. Pascalor is an independent brand and is not affiliated with any polymer manufacturer named elsewhere on this site.
