AFLAS® FFKM Elastomers
AGC Chemicals Europe has developed AFLAS® FFKM perfluorinated elastomers capable of withstanding very high service temperatures. Being fully fluorinated, FFKM grades exhibit outstanding sealing performance in all manner of aggressive chemical environments. AGC Chemicals Europe continuously develops materials for ever-evolving applications and markets, embracing future challenges.
With their outstanding chemical performance and high temperature capabilities, AFLAS® FFKM grades are perfectly suited for use in O-rings and seals in the harshest conditions.
Features
- Resistant to acid, alkali, steam, oils and solvents
- Continuous operating temperatures up to 300°C
- Retains elasticity due to low compression set
- Exceptional resistance in plasma environments
- Excellent mechanical performance even at higher temperatures
Benefits
- Long life performance in aggressive chemical environments
- Peace of mind for high temperature environments and occasional excursions
- Compressed seals require much less frequent replacement
- Low degradation rate and low particle generation leading to less contamination in process
- Maximum capability in both static and dynamic applications
Grades
AGC Chemicals Europe 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 service requirements, PM-1100 is the next level in terms of chemical performance. It is capable of continuously operating at 230°C and at occasional peaks of 250°C. It is the 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 sustains longer pressure periods, reducing maintenance needs.
PM-3500: the pure one for demanding applications
Specifically developed for services wherein high-purity is vital to the customer’s processes, PM-3500 is plasma resistant ideal for use in the etching process in semiconductor manufacture. It achieves a Shore A hardness of 70 without the need for fillers that could lead to particulate generation.
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.

† Compression Set data measured on JIS B 2401, P-26 O-ring, 25% compression, 70h, 250°C
All of the above grades are peroxide curable for ease of handling and processing. The AGC Chemicals Europe R&D team is constantly looking at ways to improve product offerings in order to push the boundaries of possibility.
