1. Description
The combi seals, inseparable entities linked by metal frames, composed of standard SC / TC / DC shaft seal rings and polyurethane anti-pollution deflectors, are particularly valued for their great ability to form an anti-pollution barrier. This polyurethane part, whose material and design forms a barrier against external impurities, makes the combi seal highly reliable.
2. Materials
NBR (Nitrile Butadiene Rubber)
Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.
Depending on their structure and fluorine content, the chemical resistance and resistance to the cold in fluororubbers can vary. This FKM-based rubber is very often used for high-temperature hydraulics and pneumatics, for industrial valves, injection/fuel systems, motor seals and high-vacuum systems
