Acrylic plastic refers to a family of synthetic, or man-made, plastic materials containing one or more derivatives of acrylic acid. The most common acrylic plastic is polymethyl methacrylate (PMMA), which is sold under the brand names of Plexiglas, Lucite, Perspex, and Crystallite. PMMA is a tough, highly transparent material with excellent resistance to ultraviolet radiation and weathering. It can be colored, molded, cut, drilled, and formed. These properties make it ideal for many applications including airplane windshields, skylights, automobile taillights, and outdoor signs. One notable application is the ceiling of the Houston Astrodome which is composed of hundreds of double-insulating panels of PMMA acrylic plastic.

 

Like all plastics, Acrylic Rod plastics are polymers. The word polymer comes from the Greek words poly, meaning many, and meros, meaning apart. A polymer, therefore, is a material made up of many molecules, or parts, linked together like a chain. Polymers may have hundreds, or even thousands, of molecules linked together. More importantly, a polymer is a material that has properties entirely different than its component parts. The process of making a polymer, known as polymerization, has been likened to shoveling scrap glass, copper, and other materials into a box, shaking the box, and coming back in an hour to find a working color television set. The glass, copper, and other component parts are still there, but they have been reassembled into something that looks and functions entirely differently.

 

The first plastic polymer, celluloid, a combination of cellulose nitrate and camphor, was developed in 1869. It was based on the natural polymer cellulose, which is present in plants. Celluloid was used to make many items including photographic film, combs, and men's shirt collars.

In 1909, Leo Baekeland developed the first commercially successful synthetic plastic polymer when he patented phenol-formaldehyde resin, which he named Bakelite. Bakelite was an immediate success. It could be machined and molded. It was an excellent electrical insulator and was resistant to heat, acids, and weather. It could also be colored and dyed for use in decorative objects. Bakelite plastic was used in radio, telephone, and electrical equipment, as well as countertops, buttons, and knife handles.

 

Acrylic acid was first prepared in 1843. Methacrylic acid, which is a derivative of acrylic acid, was formulated in 1865. When methacrylic acid is reacted with methyl alcohol, it results in an ester known as methyl methacrylate. The polymerization process to turn methyl methacrylate into polymethyl methacrylate was discovered by the German chemists Fitting and Paul in 1877, but it wasn't until 1936 that the process was used to produce sheets of Clear Acrylic Rod safety glass commercially. During World War II, acrylic glass was used for periscope ports on submarines and for windshields, canopies, and gun turrets on airplanes.

Clear PC Tubes are optically pure. Our transparent Polycarbonate tubes are often used in the stand- and exhibition building, in the furniture/interior design branches, and mostly for technical applications such as reactors. Polycarbonate tubes are reasonable UV stable and weatherproof but are not designed for long-term outdoor applications. They will yellow if they are outside for a long period.

High-quality, design-orientated applications within the architectural lighting industry can be easily created with our Polycarbonate tubes. You can create impressive lighting effects using our PC Color Tubes which are an innovative solution that fits particularly well for Lighting and architectural applications. White or frosted satin surface finishes provide excellent diffused light creating a velvety nonglare surface.

Polycarbonate tubes can be cut, sanded, drilled, etc. with the appropriate tools. They require high cutting speeds and effective cooling as their low heat conduction can easily lead to overheating and local thermal stress.

Excess friction, especially with Polycarbonate tubes can cause melting which leads to a tacky surface and difficulty machining. Drilling should never be performed without using some water-based cooling lubricant (i.e. an emulsion). For eliminating internal stress annealing may be necessary.
