HISTORY OF PLASTICS and the Development of China's Laminates and Composite Plastics Industry

The plastic industry in the United States is a thriving industry worth billions of dollars, with a growth rate that surpasses many other industries. Plastics are widely used in various key fields in the United States, such as construction, packaging, automobiles, ships, electronics, pipelines, and consumer goods.
Plastic, like metal, glass, wood, and paper, is a fundamental substance that plays a crucial role in meeting the needs of various industries in the United States. With the development of social habits, the importance of plastics in innovative concepts in various fields such as architecture, aerospace, communication, transportation, medicine, and art will continue to increase.
The history of plastic materials in the United States can be traced back to 1868, when an innovative printer named John Wesley Hayter invented celluloid, which was the first type of plastic in the United States. By combining pyrroline, a natural polymer extracted from cotton, with nitric acid and camphor, Hyatt has created a groundbreaking new substance. Celluloid was quickly and widely adopted in various industries, including the photography industry. In 1882, George Eastman used it to develop the world’s first film film. It is worth noting that this pioneering material is still in use today, but its chemical name is nitro cellulose。

In 1909, Dr. Lee Hendrik Baekeland invented phenolic plastic (commonly known as “phenol”), which was the earliest globally recognized plastic material. It is worth noting that Beckland has also developed methods for managing and altering the phenol formaldehyde reaction, enabling the production of products through heating and pressure. The ability to melt and shape materials under heating and pressure conditions remains a prominent feature of many plastics to this day。

The third major impetus in the development of plastics occurred in the 1920s with the introduction of cellulose acetate (which is structurally comparable to cellulose nitrate but is safer to refine and utilize), urea-formaldehyde (which can be refined like phenolics but can also be molded directly into a lighter-colored writing, which is more striking than the blacks and browns found in the phenolics), and polyvinyl chloride (often called PVC or vinyl).
Nylon was further established in the late 1920s through traditional research on W.T. Carothers. New, more flexible plastics were introduced every year. The commercialization of acrylic resins for signs and glass, as well as polystyrene, eventually became the third largest seller of plastics in the 1930s, virtually transforming all segments of the home furnishings, toy, and packaging markets. Melamine resins were also introduced; these later became an important component (in the form of adhesives) in the development of decorative laminate tops, vertical looks, and more.
Polyethylene – the most widely used plastic today – was developed during the Second World War for applications such as radar wire. Just a decade or two later, thermosetting polyester resins dramatically changed U.S. shipbuilding services, which were also developed for military use during the war.
Acrylonitrile-butadiene-styrene plastics (ABS, often used today in household appliance housings, refrigerator sheets, helmets, pipes, telephone headsets, and travel luggage) owe their origins to the research efforts of the Collision Wartime Program, which was designed to make large quantities of artificial rubber.
The decade of the 1950s saw the introduction of polypropylene and the development of acetal and polycarbonate, which, along with nylon, formed the center of a subgroup of the plastics family known as “designer thermoplastics. Their exceptional impact toughness, thermal and dimensional stability enabled them to compete directly and favorably with metals in many applications.
In the 1960s and 1970s, they also introduced new plastics, most importantly thermoplastic polyesters, with impressive resistance to gas permeation, making them suitable for product packaging. During this period, a subcategory of the plastics family emerged, the so-called “high-temperature plastics”, which included polyimides, polyamide imides, aromatic polyesters, polyphenylene sulfide, polyethersulfone, etc. These products were designed to meet the needs of the aerospace and aeronautics industries. These products were developed to meet the thermal requirements of aerospace and aircraft applications. Nonetheless, today they have been relocated to commercial locations where they are required to operate at constant temperature levels of 400 degrees Fahrenheit or higher. Quotes show that by the year 2000, manufacturing of plastic materials will certainly increase by 225 billion pounds in the United States alone, making it one of the most important products used in the world.
The Beginning of Plastics As with any type of product, plastics originated in nature with basic chemical components including carbon, oxygen, hydrogen, nitrogen, chlorine or sulfur. These products are removed from nature’s air, water, natural gas, oil, coal and even plant stores. Raw materials are derived from basic resources, which we call “monomers” (from “mono”, meaning one, and from “mer”, meaning unit). –in this case, a specific chemical device). Monomers undergo a chemical reaction called polymerization, which causes small particles to join together to form longer particles. Chemically, polymerization converts monomers into “polymers” (large quantities of monomers). Thus, a polymer can be defined as a high molecular weight compound consisting of relatively simple repeating devices. Monomers can contribute to the manufacture of a variety of different polymers, each with its own unique characteristics. The way in which the monomers are directly linked into the polymer, and the resulting structural setup, is a factor in the properties of the plastic. The length of the particles in the molecular chain (called the “molecular weight”) is a second factor. The type of monomer is a third factor. The polymerization of two or more different monomers (a process called “copolymerization”) is the fourth factor. The inclusion of different chemicals or components during or after polymerization is one fifth.
