In simple terms, the most essential difference between plastic and rubber is plastic deformation when the plastic deforms, and the rubber is elastically deformed. In other words, the plastic is not easily restored to its original state after deformation, and rubber is relatively much easier. The elasticity of plastic is very small, usually less than 100%, while rubber can reach 1000% or more. In the molding process, the vast majority of the molding process is complete; the rubber curing process also requires a vulcanization process.
Plastics and rubbers belong to the same high-molecular materials, mainly composed of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms, its special performance, use is also special. At room temperature, the plastic is solid, hard and unable to stretch. The rubber hardness is not high, elastic, stretch can become longer, stop stretching and return to the original state. This is due to their different molecular structures. Another difference is that plastics can be recycled and reused many times, while rubbers cannot be recycled directly, but can only be processed into reclaimed rubber before they are available. The shape of plastic at 100 degrees to 200 degrees is similar to that of rubber at 60 to 100 degrees. Plastic does not include rubber.
In other words, rubber is, in a broad sense, a kind of plastic, and plastic includes rubber. It is introduced in detail.
General industrial double-sided adhesive can be divided into two categories: acrylic adhesive and rubber adhesive. The two major categories can be divided into two types: substrate and non-substrate. (There is a substrate: add a layer of cotton in the rubber, to strengthen the glue and strength of the double-sided adhesive itself, no substrate: Pure gum to ensure the transparency of double-sided adhesive). Because the main body of the rubber compound is CR, it is used in rubber products and can easily react with the vulcanization system of rubber to turn purple. Therefore, the lighter-colored rubber products use the substrate double-sided adhesive in the acrylic adhesive (the same kind of double-sided adhesive, whether it is a substrate or no substrate, is distinguished by its own colloidal thickness.
