Simply put, the most essential difference between plastic and rubber is plastic deformation when the plastic deforms, and 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.
Plastic and rubber belong to the same polymer material, mainly composed of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms. Their properties are special and their uses are special. 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 their different molecular structures. Another difference is that plastic can be recycled and reused multiple times, while rubber can not be recycled directly. It can only be processed into reclaimed rubber before it is available. The form of the plastic at 100 degrees to 200 degrees is similar to that of the rubber at 60 to 100 degrees, and the plastic does not include rubber.
To be complicated, in a broad sense, rubber is actually a kind of plastic, and plastics include rubber. Now it is introduced in detail.
General industrial double-sided adhesive, can be divided into two major categories of acrylic adhesive and rubber adhesive. These two categories can be divided into two types: substrate and no substrate (with substrate: adding a layer of cotton to the glue, strengthening the amount and strength of the double-sided tape itself, no substrate: Pure gum, ensuring the transparency of double-sided tape). Because the main body of the rubber glue is CR, it is used in rubber products, and it is easy to react with the rubber vulcanization system to become purple. Therefore, the rubber products of the lighter color adopt the double-sided adhesive of the substrate in the acrylic adhesive system (the same type of double-sided adhesive, whether the substrate or the substrate is not used, the difference is made by the thickness of the adhesive itself.
