| − | [Kommerling, USA] White, finely-textured, flexible [[polyvinyl chloride]] (PVC) foam sheets. KomaTex has a matt, foamed surface that readily accepts inks, paints or laminants. It bonds well with most adhesives and is lightweight and flame resistant The weather resistant panel is recommended for outdoor applications. Komatex does not have an outer skin like other types of [[PVC Boards]]. | + | Colorless crystals. Titanium potassium oxalate is used as a mordant in dyeing [[cotton|cotton]] and [[leather|leather]].

| + | T.P.O. |
| − | Research by Greg Smith and Michael Samide report that some rigid, unplasticized PVC construction boards give off a sulfur containing heat stabilizer (2-ethylhexyl thioglycolate [2-EHTG]) that can tarnish silver [1]. However, they also reported finding several specific brands of PVC construction board, namely Komacel (Kommerling) and e-PVC (3A Composites) are safe for use in exhibition casework as they do not contain 2-EHTG.

| − | ==Working Properties==
| |
| − | * Screws hold in Komatex really well.
| |
| − | * No outer skin; surface is rougher and more matte vs KomaCel.
| |
| − | * Because it is fire resistant, it is good for use on the exterior of cases.

| |
| − | Less expensive than KomaCel.
| |
| − |
| |
| − | Suppliers have KomaTex in larger quantities (vs KomaCel) because it’s desired for its fire resistance in outdoor and construction uses.
