< : > Rubber and plastic are the collective name for the rubber and plastic industries. They are all subsidiary products of petroleum. They are all the same in source. However, in the process of making the products, their physical properties are different and their uses are even different. Rubber is widely used in tires. Plastics are becoming more and more widely used with the needs and uses of technology and market, and they are inseparable from daily life.
r >< :: >The difference between rubber and plastic
r >< :>Simply put, the most essential difference between plastic and rubber is that plastic deforms plastically when it deforms, while rubber deforms elastically. In other words, plastic is not easy to return to its original state after deformation, while rubber is relatively easy. The elasticity of plastic is very small, usually less than %, while rubber can reach % or more. In plastic molding, most of the product processes are completed after the molding process is completed. However, after the rubber molding process is completed, a vulcanization process is required.
r >< : >Plastics and rubber are both polymer materials, mainly composed of carbon and hydrogen atoms, and some contain small amounts of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms, which have special properties , its use is also particularly at room temperature. Plastic is solid, very hard, and cannot be stretched or deformed. Rubber is not hard, elastic, can be stretched and lengthened, and can return to its original shape after stopping stretching. This is due to their different molecular structures. Another difference is that plastic can be recycled and reused many times, while rubber cannot be recycled directly. It can only be processed into reclaimed rubber, and then it can be used in the form of plastic at a certain temperature and rubber at a certain temperature. Plastics with similar shapes do not include rubber
r >< :>To put it more complicatedly, in a broad sense, rubber is actually a type of plastic, and plastics include rubber. Now introduce it in detail.
r >< : >Double-sided tape for general industrial use can be divided into two categories: acrylic adhesive and rubber adhesive. Both of these two categories can be divided into two types: with base material and without base material (with base material: add a layer of cotton to the glue to enhance the glue quantity and strength of the double-sided tape itself; without base material: pure Glue to ensure the transparency of the double-sided tape). Because the main body of the rubber glue system is R, it is used in rubber products and can easily react with the rubber vulcanization system and turn purple. Therefore, rubber products with lighter colors all use double-sided tape with a base material in the acrylic adhesive system (the same type of double-sided tape, whether with a base material or without a base material, is distinguished by its own glue thickness.
