Vermilion® Three ‑ Shell TAT certificate of acceptance

Vermilion Three has become the first and only elastomer to receive Shell TAT approval to Shell MESC SPE 85/301.

In third party testing, O-rings manufactured in Vermilion Three achieved a ‘0000’ rating - zero damage - when subjected to ISO23936-2/Norsok M-710 testing for resistance to rapid gas decompression (RGD). The Shell MESC SPE 85/301 standard requires more challenging test conditions for RGD resistance, being carried out at 150°C, which is 50°C higher than the standard temperature required for ISO23936-2/Norsok M-710. Given that a material’s RGD performance is highly sensitive to temperature, achieving a ‘0000’ rating at 50°C above the industry test standard is a significant advance in capability over current material technology.
