What Is The Difference Between Rubber And Plastic?

- Aug 15, 2019-


    Rubber Products In a broad sense, rubber is actually a kind of plastic, and plastics include rubber.


    The most essential difference between plastic and rubber is plastic deformation when the plastic deforms. Simply put, the rubber is elastically deformed. In other words, it is not easy to restore the original state after the plastic is deformed, and the rubber is relatively easy. The elasticity of the plastic is very small, usually less than 100% and the rubber can reach 1000% or more. The molding process is completed after the molding process is completed, and the vulcanization process is required after the rubber molding process is completed.

    It is mainly composed of two atoms of carbon and hydrogen, and plastic and rubber belong to the same polymer material. Others contain a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms, which have special properties and special uses. At room temperature, the plastic is solid, very hard and cannot be stretched and deformed. The hardness of the rubber is not high, it is elastic, it can be stretched and lengthened, and the stretching can be restored to its original state. This is due to its different molecular structure. Another difference between rubber products is that plastics can be recycled and reused multiple times, while rubber can not be recycled directly. It can only be processed into reclaimed rubber before it can be used. The form of the plastic at 100 degrees to 200 degrees is similar to that of the rubber at 60 to 100 degrees. The plastic does not include rubber.


    A product made of silica gel as a raw material is called a silicone product.


    Rubber products are made of silica gel and can be used in many fields, such as baby nipples, straws in cups, cup lids on cups, bracelets, watch bands, etc. There are also foot pads under the electronic products, as well as medical products, there are many silicone products, it can be non-toxic, tasteless, and can withstand high temperatures of 200 degrees or more, low temperature -40 degrees, so the application is very extensive
