The recommended radius of curvature should be a value greater than 180 times the thickness of the sheet for PLEXIGLAS® G sheet, and 300 times the thickness for PLEXIGLAS® MC sheet.

How to polish drilled holes?

 A properly drilled hole has a smooth semi-matte finish that can be brought to a high polish.

  • A wood or metal rod approximately 1/8 inch smaller in diameter than the drilled hole is split to a depth equal to the depth of the hole plus 1/2 inch and mounted in a drill press.
  • If the inner surface of the hole is rough, steel wool or strips of emery cloth or sandpaper are wound around rod and gripped in the slot.  
  • When the inner surface is smooth, a good grade of flannel is wound around the rod and the compounds for buffing are applied.

How to clean PLEXIGLAS® acrylic sheet?

We recommend washing PLEXIGLAS® acrylic sheet with a mild soap or detergent and lukewarm water solution. Use a clean soft cloth or sponge and as much solution as possible. Rinse well. Dry by blotting with a damp cloth or chamois.

Do not use: window cleaning fluids, scouring compounds, gritty cloths, leaded or ethyl gasolines or solvents such as alcohol, acetone, carbon tetrachloride, etc.

To remove tar, grease, paint, etc., use a good grade of naphtha or kerosene. Users of these solvents should become familiar with their properties to handle them safely.
