Hygroscopic Plastics

 Outgassing: Problems Arising Out Of Thin Air





Some plastics can absorb moisture from the air.  These materials fall into the category called “hygroscopic plastics”.  The best known product in this group is polycarbonate. It’s not, however, the only hygroscopic plastic. Nylon and polyester can also absorb water vapor.

Water vapor isn’t the only substance that polycarbonate sheet can absorb.  Researchers have discovered that polycarbonate can also become saturated with oxygen. 

While absorption of moisture and oxygen isn’t always a problem, it can be, especially when you are decorating the sheet with vinyl graphics. As the plastic outgases, bubbles can form under the applied vinyl graphics.

But ever since I moved, I left my old tiles at the old place and came here to find my scrap tiles are all of irregular surfaces. ): So I had been working on a sheet of plastic wrapper pasted on my table all these while, like this; While the plastic tears easily especially when cutting/slicing, the plastic sheet also tend to move/fold around when I rolled my clay pieces. So I went to  Art Friend @ The Curve  to look for surfaces to work on. Few choices I found to be rather useful - glass (RM 4.2 for a 15 x 15 cm piece), acrylic sheets, and finally polypropylene sheets.
