Perfluoroelastomer (FFKM) elastomers offer exceptional thermal stability, outstanding long-term compression set and almost universal chemical compatibility – delivering long life in the most aggressive of media, including hydrocarbon and aqueous media, common within oilfield applications.

Isolast® XploR™ J9523 FFKM from Trelleborg Sealing Solutions combines excellent chemical and thermal properties, with outstanding low temperature capability. Ideally suited for wellhead and other drilling applications involving aggressive media where the ambient temperature above and below ground is below 0 ºC for prolonged periods. It also exhibits superior high pressure sealing performance in Rapid Gas Decompression (RGD) situations, which is supported by independent testing in accordance with institutional standards.
