Low-friction, non-cohesive fluoro elastomer
TOMBO™ No. 2670-FA-F
Rubber O-ring Fluoro-Plus
Fluoro-Plus is a special fluoroelastomer that maintains the chemical resistance and heat resistance of a regular fluoroelastomer but has significantly improved wear resistance and non-stickiness.
Fluoro-Plus is different from outer membrane coatings and is a product that undergoes treatment by way of a surface improvement method. As a result, it maintains its attributes over the long term and it experiences no peeling of the surface layer.
Standard hardness (Duro A): 70
Its friction coefficient is about 1/2 of a standard fluoro elastomer.
Its adhesion with metal is about 1/5 of a standard fluoro elastomer.
It undergoes surface modifying processing and so there is no peeling of the surface layer.
