Seal material remains flexible at extremely low temperatures
This company’s temperature-flexible Vi 840 FKM fluoroelastomer compound allows precision O-rings (photo) and elastomer seals to be manufactured to provides sustained low-temperature flexibility. It maintains low-temperature flexibility to –40°C, and conforms to the DIN EN 14141 standard. And with a TR-10 value of –40.1°C, this performance compound is suitable for use at temperatures down to –46°C, fulfilling API 6A and 6D standards, says the company. — G.
