This happens until the internal pressure of a material creates an equilibrium with the external pressure of the fluid media. If the external pressure experiences a sudden and significant drop, the gases that had permeated the elastomer escapes to maintain equilibrium. The gases migrate rapidly and beyond the elastomer\u2019s capacity to handle that change. This causes fissures and ruptures, as shown in the pictures above, and is referred to rapid gas decompression (RGD) or explosive decompression (ED).\r\n\r\nIt is well-known that fluorocarbon (FKM), despite being a widely used material, typically has poor low-temperature capabilities. To provide our customers with a low-temperature FKM sealing solution that resists rapid gas decompression, we have formulated the V9M2 compound using Viton\u2122 GLT polymer.\r\n\r\nThis specialty compound combines the high-temperature resilience of FKM with enhanced performance at lower temperatures, delivering a more versatile sealing solution. Its extremely low compression set is ideal for temperature and pressure cycling environments. It also has a strong resilience to a broad range of chemicals, including hot water and steam. V9M2 has undergone third-party testing for low-temperature valve sealing performance. It achieved an outstanding result at a temperature of -40\u00b0C per MESC 77\/312 standards for Fugitive Emission Production Testing.\r\n\r\nV9M2 Advantages:\r\n
