Globally, plastic is an important material for any economy, having a wide coverage in many industries producing goods and services. At the moment, no industry does not use plastic as an input or final consumer product
Alexander Parkesine – inventor of plastic material
Plastic more than 100 years ago, originally called semi-synthetic plastic material – “Cellulose nitrate” appeared in the late 1850s invented by Alexander Parkesine, but encountered many failures. It was not until 1862 that plastic materials became officially known to the world and the use of plastic materials at the end of the last century helped human society make important technological advances.
The mission of plastic in the 20th century
In 1922, a German chemist, Hermann Staudinger made discoveries that changed the face of the plastic industry. In the process of working with synthetic plastics, he discovered with plastic material formed from a chain of thousands of molecules linked together, called “Superpolymers” – which opened the turning point for inventing many types. New plastic materials later.
In 1921, the first injection molding machine was designed, this was the foundation for today’s plastic manufacturing machinery. In the 1930s, two strides were introduced to the mass production of the plastic industry. First, manufacturers already know how to extract oil from petroleum – polystyrene, acrylic polymers and polyvinyl chloride are all made in this way. Later, the molding technology was improved and fully automated in 1937. PVC continued to grow rapidly and was first used as a power cable in 1930.
Polymethyl methacrylate was also invented at this time, and by 1935 began to be used in the manufacture of aircraft cockpits and in other protective screens.
The first epoxy resins developed in Switzerland in 1938 were mainly used in dentistry and medicine due to their adhesive properties. Household plastics are becoming more and more popular when “Urea formaldehyde” becomes popular because these plastic products are attractive, bright and suitable for modern living errors.
In the 1940s, World War II served as a big push for the plastic industry. In terms of design technology, consumer products benefit from newly developed technologies due to war demand. The plastics are still widely used today such as Polyethylene (PE), Polystyrene (PS), Polyester, Pet and Silicon all increased strongly during the war.
Silicon began to be widely used as a waterproofing and heat resistant paints. Nilon, the first man-made fiber, was invented in the late 20s, but it was not widely used until the 1940s. With long yarns that can be pulled for weaving or knitting, this new plastic line is used to make everything from umbrella to upholstery. PVC material also really peaked in this decade.
The year 1956 was a milestone in the automobile industry when it was first witnessed plastic as the main material in the body design and roof made of unsaturated polyester reinforced with fiberglass. The combination of polyester and fiberglass later became a popular choice in the manufacture of cars and spacecraft.
Polythene (PE) was first discovered in 1933, but had to wait until the 1950s to reach its peak thanks to a safer new production method. The new material has a high melting point, which addresses the weaknesses of other plastic materials, which have been used in garbage bins, tubs, and chemical containers.
In the 1950s, plastic became the main material in the garment industry. Polyester, Lycra and nylon materials are easy to clean, wrinkle-free and are often cheaper than materials of similar natural origin.
In the 1960s and 70s, this period was a period of dramatic change in the fashion industry, the strong development of plastics was a huge advantage, with the advent of a series of alternative materials in the fashion industry. Page. Interior decoration is also known for mutant products such as inflatable chairs or acrylic lamps.
The 1970s plastic plays a backstage role for the outstanding development of the information technology industry. While mechanical and computer industries are emerging, super-polymer materials gradually replace metal. The hygienic properties of plastics also mean a great deal when used in medicine.
However, the general tastes of the 1970s had a clear shift towards synthetic materials used in the previous period, consumers preferred to return to natural materials such as wood, fabric, and metal. and leather. This trend coincided with the world energy crisis, resulting in a lack of raw materials and the first and only time in the history of the plastic industry took place a decline in the industry’s output.
In the 1980s and 1990s, the global explosion of information in the 1980s and 1990s could be realized mainly through the use of plastics. Equipment such as computers, fiber optic cables and phones all use plastic with superior properties in terms of durability, lightness, insulation and flexibility. Plastics are also more widely used in transportation. The proportion of plastic materials used in car manufacturing increased by 11% between 1974 and 1988, and in the 1980s, the first test aircraft to use entirely plastic materials took off.
Consumer habits have also changed dramatically with the emergence of supermarkets and hypermarkets and there is less and less buying fresh food from small vendors. Plastic is now widely used in packaging, contributing and playing an important role in maintaining the freshness of products during transportation from shopping centers to households.
Providing high performance at low cost, plastic has replaced other materials with many uses. Synthetic resins are currently being applied throughout the society and growth prospects in major markets such as packaging, construction, transportation … Although the industry’s explosive growth rate has slowed since 1970, but with the advent of new types and types of products that allow synthetic resins to continue penetrating into new markets and applications, especially for engineering materials, this flexible Hope to maintain its leading position in all industries and human life.
