Do you know?! Plastic history
- The beginning of the plastic era
- Development of practical plastic
- Many new plastics are developed
The beginning of the plastic era
In 1835, the powder of "polyvinyl chloride" was invented in France. Four years later in 1839, "Polystyrene" was invented this time in Germany. Although it is still a famous plastic, these plastics at that time had problems such as durability and although it was developed as a plastic, it was lacking in practicality as an industrial product.
Development of practical plastic
The development of plastics with industrializable practicality will be talked about several decades later. "Celluloid" was developed in the United States in 1870. At that time, the story used as a ballad of billiards as an alternative to ivory is famous. However, celluloid had a disadvantage of easy ignition.
A few years later, "phenolic resin" was developed in Germany in 1872, but it was not industrialized at that time. This was put into practical use in the United States in 1909 after several decades, "Bakelite" industrialized phenolic resin was developed and spread. It can be said that this is the first artificially synthesized plastic in the history of mankind.
Many new plastics are developed
Later, many new plastics will be developed. The main types of plastics and the year of development were as follows.
- ・Urea resin (1918)
- ・Cellulose acetate (1922)
- ・Vinyl acetate resin (1928)
- ・Methacrylic resin (1930)
- ・Styrene resin (1930)
- ・Vinyl Chloride Resin (1931)
- ・Polyethylene (1939)
- ・Polyamide resin (1941)
- ・PTFE (1942)
- ・Epoxy resin (1943)
- ・ABS resin (1948)
- ・PET (1948)
- ・Polypropylene (1957)
- ・Polycarbonate (1958)
- ・Polyacetal (1958)
- ・Polyimide (1964)
- ・Modified PPE (1967)
- ・PPS (1970)
In the early days, Germany is the center of development and in the late period the United States is the center of development.
World War II and plastic
Metals such as iron, copper, and aluminum became valuable in military use in the Second World War, so the demand for plastic increased as an alternative. After the end of the Second World War, plastic was inexpensive and it was evaluated as disposable, and it was rapidly spreading to the market. World War II was a major turning point for plastics.
What do you think. I think that the history of plastics is less than 100 years old and it can be understood that it has developed rapidly. I would like to expect new plastic development that will continue to create a new page in the history of plastics.
