Styrenic materials, utilized in subsea wet insulation, have been exposed in long-term tests for 12 months at elevated temperatures and pressures in seawater according to ISO 12736:2014. The performance of these materials under this harsh exposure regiment shall be presented and compared to the performance of traditional polypropylene materials.
