Product details of 1A Films:
To achieve a defined surface structure and a consistent and a repeatable quality, stable process parameters like pressure and consequently the load (force) on each individual grit (crystal) are accomplished by using a polyethylene foil as backing material. This foil is coated with abrasive grit according to the CIS standard (Calibration for Industrial Standards) and is secured with a special bonding.

Finishing film typically consists of the backing material, the abrasives particles and the bonding agent.

   a) Backing material:
            a tear and stretch resistant base film, usually polyethylene foil (3Mil=75µm)
   b) Abrasives:
            The particles are selected according to their dimension and slurry coated or electro statically spread on the base film

           
   
    c) Bonding agent:
               A bonding agent based on synthetic resin secures the abrasive particles to the backing material.
