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.
