Engineered for extremes
PU Dissolvable 85X
Read the code: PU, DIS duty (dissolvable elements), 85 Shore A, X for another cure system, 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 85 Shore A degradable elastomer for frac plug elements, wipers and completion seals that must hold pressure during the job and then break down in well fluids, so no mill-out run is needed.

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 |
|---|---|---|---|
| Degradation curves | In-house method, published with results | Customer brines at 60, 80 and 100 °C | Planned |
| Pressure holding | In-house plug fixture | At temperature, before degradation starts | 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.
