Do you know the difference between plastic and rubber?
Everyone is familiar with plastics, but the understanding of rubber is still very vague. Sometimes rubber is regarded as plastic. Do you want to know the difference between plastic and rubber? Then take a look at the following introduction.
Simply put, the most essential difference between rubber and plastic is that plastic deforms when plastic is deformed, but rubber deforms elastically. In other words, it is difficult to restore the original state after plastic deformation, but it is much easier for rubber. Therefore, it can be said that the elasticity of plastic pipes is very small, usually less than 100%, while the elasticity of rubber can reach 1000% or more. Most of the plastic molding process is completed and the product process is completed, but after the rubber molding process is completed, a vulcanization process is required.
Broadly speaking, rubber is a kind of plastic, so rubber is a subcategory of plastic. The rubber and plastics that we usually hear or say are the collective term for the rubber and plastics industries, because they are all subsidiary products of petroleum, and they are all the same in source, but the physical properties of the products are different in the process of production, so they The purpose is also different. Rubber is mainly used for tires, and with the increasing demand and use of technology and market, plastics are inseparable from our lives.
Rubber and plastics are both high-molecular materials. The main components are carbon and hydrogen. In addition, there are a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms. Although their composition is similar, each has its own characteristics. Plastic is solid at room temperature, very hard, and cannot be stretched and deformed, but the hardness of rubber is not high, so it is elastic and can be stretched to become longer, and it can return to its original state when it stops stretching. This is mainly because the molecular structures that make up them are different. There is another difference between them. Plastic can be recycled many times, but rubber cannot be recycled directly. It needs to be processed into recycled rubber before it can be used. The shape of plastic at 100 degrees to 200 degrees is very similar to that of rubber at 60 to 100 degrees.
