Proper Storage of Plexiglas sheetPlexiglas G sheets are covered or "masked" on both sides with a tough Kraft
paper or polyethylene film coated with a pressure sensitive adhesive that does
not attack the surface of the Plexiglas. (Note: Plexiglas may be ordered
unmasked and some patterns do not come with masking.) The masking helps prevent
scratching during normal handling and fabrication operations, and should be
kept in place for most cutting and machining procedures. If the sheet is
thermoformed, however, or if it is installed outdoors the masking must be
removed. The masking will protect the Plexiglas during normal handling, but
sheets should not be slid against one another or across rough or dirty
surfaces.
Storage Rooms - In general, the fire precautions that are observed in
connection with the storing of ordinary combustibles such as wood and paper
should be observed when storing Plexiglas. In addition, storage rooms should be
well ventilated. Air should circulate freely and should be relatively moist and
cool. The temperature should no exceed 125 degrees F. Storing Plexiglas sheet
in a hot, dry environment may eventually cause the adhesive used on the masking
to dry out, making it difficult to remove from the Plexiglas. Excessive
moisture may cause the masking paper to deteriorate and reduce its
effectiveness for protecting the Plexiglas.
Storage Racks - Masked sheets of Plexiglas are best stored on edge in "A" frame
storage racks. These racks give full support to the sheets yet permit easy
removal of individual sheets from any rack. If masked sheets must be stored
flat, care should be taken to avoid trapping chips and dirt between the sheets.
Such chips and dirt may scratch or press into the surface of the material.
Piles of Plexiglas sheet should not be over 18" high. Small sheets should be
stacked on the larger ones to prevent unsupported overhang.
