Celluloid refers to the old brand name used in plastics, and it is the earliest artificial plastic.
History:
In 19th century Europe, playing billiards was a very popular entertainment activity in the upper class. Early billiards were made of ivory. In order to obtain ivory, more than 2, elephants were killed every year. Because of the scarcity of ivory, the output was very limited, so some people offered a reward of 1, US dollars for alternative materials for making billiards.
In p>1869, a mixture of nitrocellulose, camphor and ethanol was heated under high pressure, and then hardened under normal pressure to make cheap billiards, which won the prize. As a sport, billiards began to be gradually popularized in society. This material made of cellulose is celluloid. "Celluloid" became the earliest artificial plastic.

Features and uses:
Celluloid is often thinner and lighter than bakelite. When heated to a higher temperature, it will become brittle and crack. Even some celluloid sheets are flammable. Although they are more brittle than bakelite, they can still be bent or twisted. Under hot water, most celluloid has a taste like vinegar or old camphor. Celluloid jewelry may be damaged by moisture, extreme temperature or chemicals. Celluloid stored in a closed environment for a long time will also be very dull or even cracked.
celluloid has a variety of uses, far beyond the scope of billiard tables. The most common uses are table tennis, ornaments, headwear, musical instrument decoration and plucking. Other uses are in chemical industry, aerospace, machinery, printing and dyeing, building materials, decoration, packaging, cosmetics, gift packaging and other fields.

The difference between celluloid and plastics
Celluloid generally refers to celluloid.
celluloid refers to the old brand name used in plastics, and it is the earliest commercial synthetic plastic. It is a substance formed by adding nitrocellulose and camphor to improve its plasticity. Colorless and transparent, it can be used to make film films and imitate tortoiseshell and ivory.
Related information:
In the manufacturing process of early plastic products, many people brought their originality into play. Opaque and translucent celluloid sheets are alternately stacked and rolled to make articles that were previously made of ivory.
imitation hawksbill is also a particularly popular item. Many years later, the natural properties of plastics were developed because of their unique advantages, not because of imitation of natural substances. Despite the rise of modern synthetic resins, nitrocellulose plastics are still used, and camphor is also the best plasticizer in the manufacturing process. However, no celluloid can achieve sufficient durability in artistic applications.
