Empaistic structure
GST up to and including 2 mm radial thickness in PTFE materials are as standard supplied with Empaistic structure on the sliding surfaces.
This structure comprises small lubricant pockets on the surface which improve the initial lubrication and promote the formation of a lubricant film. They also help to protect the seal system through their ability to embed any foreign particles. In order to be able to use the strip material for both piston and piston rod guides, the rings have this same empaistic structure on both sides.
