Summary of 🤖La Historia del plástico😱El origen del plástico📎La Evolución del plástico🗳

00:00:00 - 00:15:00

This video discusses the history of plastic and the evolution of plastics. It covers the origins of plastic and how it was initially not very successful due to its high production cost. However, it was a major step in what we can consider the material of plastics, which began with primitive polymers in which we have developed a great family of plastics today.

• 00:00:00 The plastic material is a term used to describe a wide range of synthetic or semi-synthetic materials that are used for an immense number of applications. We look at where we look and see plastic used in products made from plastic for a cleaner, easier, safer, and more agreeable life. We find plastic in packaging, clothes, buildings, medical devices, cars, and more. Plastic materials are organic materials, just like wood, paper, or cloth. The main materials used to produce plastic are natural, like cellulose, carbon, natural gas, salt, and oil. Plastic became a preferred material in the 20th century because it allows for an equitable balance today in need for today's society. The term "plastic" originates from the Greek word "plástico" which means "able to be molded", and refers to the material's plasticity during manufacturing. Over the past 50 years, the plastics industry has developed at an astonishing rate, with polymers entering our lives in the 1950s. Our era will be remembered as the era of polymers, said Nobel Prize laureate Paul John Flory. The future belongs to techno-polymers, products produced at a limited scale but essential for the progress of humanity. Plastic has invaded our culture
• 00:05:00 This video discusses the history of plastic and the evolution of plastics. It covers the origins of plastic and how it was initially not very successful due to its high production cost. However, it was a major step in what we can consider the material of plastics, which began with primitive polymers in which we have developed a great family of plastics today, known as cellulose, in 1868. The company, Phileas Poindexter, promised a prize of 10,000 dollars to the first person who could develop a product that could replace animal skin in the manufacture of balls. John Wesley Haigh, who was working at the time on this research, improved the product developed by Park and achieved a commercially viable product, substituting oil of ricin for alcanfor. This product was called celluloid and the balls produced can be considered the first product made in plastic materials. The celluloid was patented in 1870. The first factory for new plastic materials, called the Alaband dental plate company, was founded in 1870. Its name is explained with the fact that one of the first uses of celluloid was experienced by dentists. They were happy to replace with it the rubber vulcanized then extremely expensive used for obtaining dental impressions. The celluloid was used for
• 00:10:00 In 1920, chemistry professor Friedrich Frbruck at the University of Fribourg in Switzerland published theoretical studies on the structure and properties of natural polymers, including cellulose and synthetic polymers. He proposed the theory that these long, linear molecules were chemical structures called macromolecules. Stalin's theory of linear polymers, which was not accepted by the scientific community at the time, led to his receipt of the Nobel Prize in Chemistry in 1953. In the 1950s, other significant progress was made in the study of polymers with the discovery of polymerization by chain-growth (stereomerization), and in the 1960s, new polymers such as polyethylene were created through organic polymerization. In the 1970s, polymers became widely used in a variety of products, such as wood, cardboard, and plastic. In the 1980s, polymers replaced some lighter alloys as the principal materials in many industrial applications. Polymers continue to be a major industrial sector, with ongoing research and development into increasingly versatile polymers with a wide range of chemical and physical properties. The world would not be able to conceive of modern technology without plastics. From the ancient and esteemed cellulose nitrate substitute used in finer materials such as Jaen
• 00:15:00 The history of plastics can be traced back to ancient times, and today many well-known names in the field are known by most people. Examples include Bayer, Kutcher, nylon, Dupont, and Baquelita. These materials have become a part of our everyday lives, and their names form part of the history of plastics.
