Materials: PMMA (polymethylmethacrylate)
The polymethyl methacrylate is another thermoplastic vinyl polymer. It was invented in 1928 and marketed in 1933 by the German Chemical Company Röhm.
EIt’s known to the public under the trade name Plexiglas, but it can also be found under other names depending on the company that produces it.
Chemically it is a polyester and its formula is as follows.
Its most important characteristic is transparency, much greater than that of the glass. Thanks to this it is possible to use it to achieve the transparent walls of aquariums ocean in which the wall thickness can reach 33cm (13in). A similar wall made of galss would be completely opaque.
Mixed with suitable substances to help regulate its hydrophobicity, becomes part of the composition of acrylic paints.
In this case too, below we have some images of objects made of this material.
