What is the difference between rubber and plastic
Rubber and plastic is a general term 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 products, their physical properties are different, and their uses are even more Different, rubber is widely used in tires, and plastics are becoming more and more widely used with the needs of technology and market, and they are inseparable from daily life.
Simply put, the most essential difference between plastic and rubber is that plastic deformation occurs when plastic deforms, while rubber deforms elastically. In other words, plastic is not easy to return to its original state after deformation, while rubber is relatively much easier. The elasticity of plastic is very small, usually less than 100%, while that of rubber can reach 1000% or even more. After most of the plastic molding process is completed, the product process is completed; and after the rubber molding process is completed, the vulcanization process is required.
Both plastic and rubber belong to polymer materials, mainly composed of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms, which have special properties and uses. At room temperature, plastic is solid, very hard, and cannot be stretched and deformed. The rubber hardness is not high, elastic, can be stretched to become longer, stop stretching and return to its original shape. 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, and can only be processed into reclaimed rubber before it can be used. The shape of plastic at more than 100 degrees to 200 degrees is similar to that of rubber at 60 to 100 degrees, and plastic does not include rubber.
To put it complicatedly, in a broad sense, rubber is actually a kind of plastic, and plastic includes rubber. Now introduce it in detail.
General industrial double-sided adhesive can be divided into two categories: acrylic adhesive and rubber adhesive. And 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 strengthen the glue volume and strength of the double-sided adhesive itself, without base material: Pure colloid, to ensure the transparency of the double-sided tape). Because the main body of rubber glue is CR, it is used in rubber products, and it is very easy to react with the vulcanization system of rubber and turn purple. Therefore, for lighter-colored rubber products, double-sided tape with a base material in the acrylic adhesive system is used (double-sided tape of the same type, whether with a base material or without a base material, is distinguished by the thickness of its own glue.
