foils rigid, porous microcellular foams that are characterized by excellent stability at high temperatures (and thus at high speeds).

Unlike conventional methods, such as pitch polishing, this process reduces polishing time by approximately 50%.

Polyurethane foils are rigid, porous microcellular foams that are characterized by excellent stability at high temperatures (and thus at high speeds).


What is Polyurethane?

We recommend using Pattex (contact adhesive) or self-adhesive polishing foil to attach it to the base.

It is recommended to roughen the surface from time to time using a brass brush to ensure a stable process with consistent removal rates.
