Resisting damage from changes in temperature is important insurance against failure for seals, o-rings and other sealing parts. FKM fluoroelastomers resist hardening and embrittlement for up to 10,000 hours of use in air and in a temperature up to 204°C. They are able of withstanding short temperature bursts up to 315°C. And, with the high-temperature capability of FKM fluorocarbon, some users can actually increase operating temperatures to improve productivity.

FKM fluorocarbon is effective at low temperatures also.

Effect of Temperature on Hardness on FKM fluoroelastomers

The hardness of elastomer vulcanizates decreases as the temperature increases. The amount of the loss of hardness depends upon the nature of the elastomer, the degree of cure, and the amount of plasticizer which is included in the compound.

Here is a convenient rule of thumb: At any temperature between 250°F and 500°F (121°C and 260°C) compounds of FKM fluoroelastomers are 15 to 16 durometer points softer than they are at room temperature. Accordingly, if 75 durometer A is required at 300°F (149°C) then a room temperature application would require hardness of about 90 A.
