18 in. x 24 in. x .157 in. White Corrugated Twinwall Thick Plastic Sheets (15-Pack)

I do appreciate the technical answer. But, I'm not a Polymer Chemist. I'm seeking a pragmatic answer. A drawer for hand tools. A drawer for clothes. A drawer for toiletries. A drawer for a first aid kit. I also understand that there is a difference between supporting the weight of an object and withstanding the impact of an object that slides inside the hypothetical drawer. Perhaps a screwdriver inside the drawer is plenty light enough but it punctures the side wall when it it moves as the drawer is opened? With this in mind, I'll likely utilize hook-and-loop attachments to help with organizing the contents and keeping them from moving around. Perhaps I went to the wrong link? Here's the initial response from Coroplast: "Coefficient of Linear Thermal Expansion, (10 to the -5th) in./in./ degrees F, ASTM-D696: This test measures the change in length of a specimen under controlled conditions within a specified range of temperatures. The temp. ranges given were use and a calculation done to determine the coefficient linear thermal expansion by multiplying the coefficient times 10 to the -5th, times the length of the sample (in.), times the difference in temp. change in Celsius. Example: A sample 144" long @ 54 degrees F differential would be calculated as follows: Coefficient = 6.9, thus: (10 to the -5th in./in./degree F) = (6.9 x [10 to the -5th] x 144" x 54 degrees F) = .000069 x 144" x 54 degrees F= .5365"/144"/54 degrees F, thus, a sheet will expand approximately 1/2' in 144' with 54 deg. F range, (32 deg.F to 86 deg.F)."

No, the plastic sheet cannot be used as a dry erase board.

Yes. They can be cut. Google variations of "working with corrugated plastic" for all sorts of great ideas for working with this material. Including cutting, bending, and welding (glueing).

Yes. But, you may not care for the appearance. And, over time, sun exposure will alter their color.
