Japan developed a memorable plastic

A few days ago, the Department of Engineering of Yamagata University in Japan and the local enterprise group jointly developed a new type of plastic that is bent at room temperature and can maintain its bending state even if the force is lost. This is the first time in the world.
According to reports, the production of this new type of plastic requires a certain proportion of rubber and metal flakes to be added to the resin, and it must have sufficient toughness and hardness by being thoroughly mixed. In principle, the chemical structure of plastics is formed by the intertwining of lock-like macromolecules, and the lock-like macromolecules are connected by carbon atoms such as chains. This lock-like structure is the main structure of plastic, can be called "main lock", "main lock" is also attached to the "side lock", by changing the "side lock", you can change the type of plastic, plastic nature is also Will change with it. Softening of plastics after heating is due to the fact that the molecular activity becomes active due to heating, the distance between the molecules is enlarged, and the connections between the molecules become loose.
This new material can be processed at room temperature. The plastic can be freely changed in shape by hand like a wire, and has excellent durability. If you use this new type of plastic in your car, you can save weight, save fuel, and you don't have to worry about rust. In addition, this new type of plastic can be made into a wire-like woven into a bra. This type of bra is naturally shaped and comfortable. However, this plastic also has its limitations. Its heat-resisting temperature is 120 degrees Celsius, which is 30 degrees Celsius lower than the temperature needed to paint the body of a car.
