Comparison of Fluoroelastomer Performance
AFLAS® FFKM Grade Range
AGC has developed a range of different AFLAS® FFKM products for various applications depending on the service conditions or other specific needs.
PM-1100: the introduction to FFKM
- When FEPM and FKM-type elastomers don’t meet your requirements, this is the next level in terms of chemical performance. It is capable of operating at 230°C continuously and occasional peaks of 250°C. Our most affordable grade for general applications.
PM-3000: the capable all-rounder
- The next level up from PM-1100. This grade has a continuous service temperature of 250°C with peak temperatures around 270°C. With improved compression set, PM-3000 will sustain pressure for longer periods meaning reduced maintenance needs.
PM-3500: the pure one for demanding applications
- Specifically developed for applications where high-purity is vital to the customers’ processes, PM-3500 achieves a Shore A hardness of 70 without the need for fillers that could lead to particulate generation. It is plasma resistant and therefore ideal for use in the etching process in semiconductor manufacture.
PM-5000: the ap-peel-ing one
- Utilising a nitrile cure system, PM-5000 will run at 300°C continuously. It has been developed with improved cold compression set and low sticking force.
PM-5500: the high temperature one
- Also utilising a nitrile cure system, PM-5500 is capable of continuous operation at 300°C. Shore A hardness of 68 can be achieved without fillers, making it ideal where plasma resistance is required at very high temperatures.
The above grades are all peroxide curable for ease of handling and processing. Our R&D team is constantly looking at ways to improve our offering in order to push the boundaries of possibility. If you have any specific requirements or ideas you would like to discuss, please get in touch.
AGC also manufactures a range of FEPM elastomers for chemically demanding applications under conditions less severe than would require an FFKM. To learn more, please click here.
