FKM |
FKM is a fluorocarbon elastomer with high thermal and chemical resistance. Its broad-spectrum resistance is relatively good. It is resistant to compression and is not easily deformed, even at high temperatures. |
-20/+200℃ |
FKM is known especially for its low gas permeability and excellent ozone resistance, weather resistance and aging resistance. |

PU |
PU materials display higher mechanical strength, high wear resistance, extrusion resistance, high-pressure load capacity, and high tear resistance and elongation. It also has good flexibility and very good aging and ozone resistance. |
-45+110℃ |
PU materials are applied to mineral oils and greases, hydraulic oils, silicone oils, greases, highly non-flammable hydraulic fluids HFA and HFB and water with the temperature up to 50°C. |
