The history of Perspecs seats is fascinating. History dates back to 1843, when the first acrylic acid was created. German chemist Otto Röhm patented and registered the PLEXIGLAS trademark in 1933. This is important because what is commonly thought of as plexiglass has become a well-known term such as Kleenex, and you may have forgotten that plexiglass was its own name. Therefore, acrylic glass was used for underwater periscopes and aircraft towers. Since then, acrylic glass has become a household item.
There are really two types of plastic. A plastic molded into a permanent shape, flexible and remoldable thermosetting. Poly (methylmethacrylate) (PMMA) is a clear thermoplastic. PMMA is commonly known as acrylic glass. Some brands are 4mm perspex sheet Plexiglas, Lucite and Perspecs. PMMA is often a cheaper alternative to polycarbonate (PC). Another advantage PMMA has over computers is the absence of the potentially harmful bisphenol A subunit found in polycarbonate.
Methacrylate sheets are similar to glass
in that they are ransparent, but in many ways they are superior to glass. It is stronger than glass, more impact resistant, and weighs only half. The scratches can be polished and high quality acrylic will not turn yellow. Unlike glass, it does not break into millions of sharp pieces. Instead, the poly is divided into larger pieces, which are almost dull and easy to see with a negative eye. Acrylic is manufactured on sheets of various thicknesses. Acrylic is mainly composed of petroleum. Cutting the acrylic sheet is very easy and can be glued without problems.
Methacrylate sheets have a variety of uses. Various windows such as airplane windows, police windows, race cars, etc. are made of this material. (The use of methacrylate sheets in race cars is easier and faster than using glass.) Advertising and shopping signs are often made of brightly colored acrylic, and thermoplastics are corrugated. Even the roofing material is made of acrylic sheet because it can be made into. In addition, methacrylate sheets are used not only as artist media, but also for framing. The methacrylate sheet can also be turned into furniture. Acrylic sheets have a wide range of uses!
