Engineered for extremes
HNBR H2 80P
Read the code: HNBR, H2 duty (hydrogen service), 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 low-temperature HNBR for hydrogen service: decompression in 100 % hydrogen, sealing at −40 °C as fuelling protocols require, and permeation data stated.

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 |
|---|---|---|---|
| Station O-ring requirements | ISO 19880-7:2025, with a dispenser or valve maker | Up to 70 MPa nominal working pressure, −40 °C to +65 °C, on the customer housing | Planned |
| Rapid decompression in hydrogen | ISO 23936-2 Annex B adapted to 100 % H2 | 100 % H2 at up to 87.5 MPa, 65 °C, 8 cycles, 5.33 mm section | Planned |
| Low-temperature sealing | Product-configured O-ring test (method published with the report) | Sealing at −40 °C at rated pressure; leak onset temperature reported with TR10 of the same lot | Planned |
| Permeability | ISO 2782-1 | Hydrogen at 23 °C and 65 °C | Planned |
| Low-temperature cycling | With gas pre-cooled as in SAE J2601, with a dispenser maker | Pressure cycles at −40 °C (number agreed with the maker) | 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.
