Working With PALSUN® & PALTUF®
PALSUN & PALTUF can be cut, sawed, drilled, bent - hot or cold, bonded and thermoformed.
Detailed instructions appear in the “PALSUN Technical Manual”.
Cleaning
PALSUN & PALTUF sheets can easily be cleaned with a soft cloth made from 100% cotton using generous amounts of
detergent and water. It is best to use mild dish cleaning preparations. Commercial spray cleaners are available. Please
consult with your local PALRAM agent or representative for recommended commercial preparations available locally.
Sawing and Cutting
PALSUN & PALTUF sheets
can be cut with band-saws,
handsaws, circular saws and
other cutting tools. (Refer
to the “PALSUN Technical
Manual”). Notwithstanding
the multiple possibilities, the
following table indicates the
cleanest cutting options.
Bonding
It is possible to bond PALSUN & PALTUF sheet to itself and to other materials. Please consult the “PALSUN Technical Manual”
(Available at the PALRAM web site).
Bending
Cold Bending
PALSUN & PALTUF sheets may be installed with a
stressed curve to create an arch or dome, as long as
the curve and resulting stress is within the specied
limits. This stress will fall within an acceptable limit and
there will be no eect on the sheet characteristics if the
magnitude of the radius is at least 200 times that of the
sheet thickness, as indicated in the following table.
Hot Line Bending
If the polyethylene masking was removed before processing, verify that the sheet is clean. If not, clean following the
instructions at the bottom of the next column. Using this method, PALSUN or PALTUF sheet is locally heated to 150-160
°C (300-320 °F) with a radiation heater (e.g. electrical resistance wire). When using single-sided heating, the sheet must be
turned over several times. After heating, the sheet is bent to the desired angle. Due to immediate relaxation during bending
and in order to obtain the desired angle, an over-bend might be required in hot line bending.
Stress Level
Both cold and hot bending (if the sheet is not heated suciently) PALSUN & PALTUF sheet induces stress in the sheet. The
residual stresses will reduce the impact strength of the material along the bend and may limit the use of this method to
less demanding applications. Almost completely stressless bends may be obtained using the annealing method (heating
of the bent sheet).
