Dustless Paper For Use In Cleanrooms (OK Clean RN)
Office/printer paper with little dust generation.
[Features]
· Office equipment made from carefully selected pulp and special resin, enabling ultra-low generation of dust when used in cleanrooms.
· Neutralized paper that is ideal for storage as it does not cause rust generation, discoloration, or corrosion when it comes in contact with metal.
· Quality and economy have been realized by permeation with a special resin with disaggregative properties, and recycling is possible.
[Applications]
· Printing by hand or printer in a cleanroom.
Printer Paper That Does Not Generate Dust Even When The Fibers Are Torn Off Due To Careful Selection Of Pulp And Impregnation Of A Special Resin
Clean pack in units of 1 ream (250 sheets).

Performance Properties And Quality Properties Of Dust-Free Paper For Clean Rooms (OK Clean RN)
Performance Properties
The values are for ≤0.3 µm dust (particles/0.02 CF)
Perform the following tests inside the clean bench, absorb 0.02 CF (cubic feet) of air during the test and measure the dust using the particle counter.
Crumpling: Hold both short sides of one sheet of an A4 sample, and crumple together for 2 minutes at a rate of 1 time/5 seconds.
Rubbing: Mount such that the front and back sides overlap on the rotating disk and fixing plate of the rubbing tester for a 14 cm × 14 cm rubbing sample, and rub them together for 2 minutes.
(Rotational speed: 500 rpm; contact torque: 1 kg·cm)
Tester: Rion Co., Ltd. KC-14 Particle Counter.
