[T515]The History Of Plastic
by Dr Barry Eppley, Dr
While the subspecialty of medicine known as Plastic Surgery (one of the 22 recognized specialties of medicine) is now so incredibly common, there are few who would not know what it is. But yet, I will occasionally get asked this question by a new patient during our consultation...'now tell me where the plastic goes'...or...'will the plastic used in the operation get infected?' Indicating that some still believe that the name 'plastic' in Plastic Surgery relates to a material and that plastic surgery operations involve putting in plastic materials.

While plastic surgery as a medical specialty and synthetic plastic materials share incredibly similar time periods in development, there is no direct correlation between the two. Plastic Surgery was not given its name because it used plastic materials in surgery. The word, 'plastic', as used in Plastic Surgery comes from the Greek word, 'plastikos', meaning to mold, shape, or give form. And this is certainly an accurate description of what Plastic Surgeons do...shape or mold human tissues into recognizeable body parts for either reconstructive (missing) or for cosmetic (existing) purposes. Plastic Surgery organized itself into a formal society in 1931 with the formation of the American Society of Plastic and Reconstructive Surgery, recently condensed to the American Society of Plastic Surgeons. It's first formal training program began several years earlier in 1924 with the establishment of the first plastic surgery residency at Johns Hopkins in Baltimore. Formal board-certification in Plastic Surgery started in 1937 which dramatically raised the standards for the specialty.

Plastic materials developed right around the same time frame as Plastic Surgery. The earliest true thermosetting plastics had their beginning in the late 1800s with the commerically successful product known as Bakelite introduced in Britain in the early 1900s. But DuPont with its polyamide (nylon 66) plastic in the 1930s popularized the material here in the United States. New plastics followed quickly such as polystyrene and polymethyl methacrylate. (acrylic). All these plastic materials become tremendously popular and necessary during World War II as components of many military products such as aircraft canopies and radar units. And here is where plastic materials share another similarity to Plastic Surgery...their development was propelled by wars, WWI and WWII. Military conflicts and the need for personal protection (plastic materials) and in the treatment of their war-related injuries (Plastic Surgery) served as a catalyst for both of their developments.

A final sidenote of both of their pre-WWII history is that they similarly converged to deal with a growing problem in the 1930s...motor vehicle accidents. As cars became more common, so did auto accidents and injuries from the shattering of glass windshields. Severe facial lacerations from the shattering of glass windshields was common at the time. Plastic surgeons were a loud voice about this problem and spurned manufacturers, such as DuPont and Monsanto, to develope more-shatterproof windshields. As Plastic Surgery performs many huundreds of different operations from the face and throughout the body, very few have ever actually required plastic materials to make the operation successful. While breast and facial implants, which are very common and popular cosmetic operations today do use synthetic materials, they are a silicone-based rubber material. To be chemically accurate, not a true plastic material. Only one operation in all of Plastic Surgery has ever really used a plastic material and that is an acrylic cranioplasty where a section of the skull is replaced by a 'plastic piece'. While not as commonly done today, acrylic cranioplasties are still done by some Plastic Surgeons and neurosurgeons as well.

Plastic acrylics are used in so many applications, in so many areas of life; it's hard to imagine a world without them. Where would we be had the science behind this revolutionary material never been explored? If acrylic had never been developed, would we be stuck with heavy, expensive objects instead of the relatively light and inexpensive materials we are familiar with today? What would brochure holders, brochure displays, racks, counter displays, donation / suggestion boxes and point of purchase (p.o.p) displays be made from? We all take it for granted, but the history of plastics and acrylics is worthy of understanding.

?Plastic? means to form or model something. This helps to understand the overall concept. It all really started in 1773 with the discovery and isolation of the compound ?urea?, which is found in the urine of mammals and other higher forms of animal life. In 1828, when urea was synthetically produced, the foundation for phenol-formaldehyde plastics was formed. That brings us to 1843 when an acrylic acid preparation was reported. Following that, Dr. Otto Rohm published the results of his research with acrylic resinoids in 1901. His thesis, "On the Polymerization Products of Acrylic Acid? explained how the polymers obtained in his research had simultaneous properties of a tough, flexible glass and a rigid plastic.

Next came Dr. Leo Baekeland. In 1909, he secured the first patent for phenol- formaldehyde, which he combined to form a resinous substance, a phenolic plastic. He called it "Bakelite". This material could be softened with heat and then molded into shape. It could then be set into final form by continued heating under pressure while in the mold; a true plastic. This was revolutionary. As a result, Baekeland's discovery triggered the imagination and research of organic chemists worldwide.

Acrylic resins started being used in 1931 for industrial coatings and laminated glass binders. The better known derivative of methacrylic acid, polymethyl methacrylate, was not introduced until 1936 as a transparent sheet and in 1937 as a molding powder. This marked the start of the acrylic era and the Plexiglas revolution.

In World War II, acrylic sheet played an important role as a bullet resistant glazing in warplanes because it was light, strong and could be easily formed to fit into the structural designs of aircraft. It was at this time that Plexiglas started being used in homes and factories for safety glazing, electrical and chemical applications, skylights, windscreens and many other uses.

Some key dates:

? 1911: Research commenced in the field of acrylics.

? 1928: Methyl methacrylate was synthesized in the laboratory.

? 1933: A method was found to cast methyl methacrylate between two plates of glass and to polymerize it inside this cell. This was a crystal-clear, hard and break-resistant plastic.

? 1934: Initial applications were for cover glasses, watch glasses and lenses for protective goggles.

? 1950: New fields of application included shop window displays, protective screens around machine tools, jointless tubes for conveyors etc. The procurement of raw material returned to normal after World War II.

Today, acrylics are used in millions of unique products, including brochure displays, racks, counter displays, donation / suggestion boxes and point of purchase (p.o.p) displays. There is one thing you can say: The beauty, simplicity and low cost of acrylic continues to make it one of the greatest manufacturing materials in the world.
