- SUMIKASUPER E101
Wholly aromatic polyester resins in SUMIKASUPER E101 Series have excellent abrasion resistance, self-lubricating properties, chemical resistance and heat resistance.
When added to solid lubricants such as polytetrafluoroethylene (PTFE) resins and graphite, SUMIKASUPER E101 makes them resistant to abrasion and compression creep and improves their sliding properties.
