The Difference Between Rubber Rollers And Metal Rollers

Table Of Contents For This Page

1. Material difference

Rubber: Rubber is a natural polymer compound whose molecular main chain consists of carbon, hydrogen and oxygen elements. Because it has good comprehensive performance, it is widely used in chemical, construction, textile, medical and other industries. In the industry, rubber hoses made of rubber are commonly used to transport liquids or gases, etc. According to the different manufacturing methods, they can be divided into three types: raw rubber (unvulcanized rubber), blended rubber (semi-finished products that can be reprocessed into various products) and plasticized rubber.

Metal: metal is a kind of conductive material, with excellent thermal conductivity and ductility, as well as high strength and hardness and other characteristics; metal materials are diverse, according to the use of steel and non-ferrous metals; non-ferrous metals can be divided into two categories of alloy steel and stainless steel; according to the smelting method, there are mainly arc metallurgy and non-arc metallurgy two categories.

2. Different elasticity

Rubber has a good elastic recovery rate (i.e. resilience), when the external force removed can quickly return to the original shape and maintain a certain degree of softness; and metal materials do not have this feature.

3. Different degree of temperature resistance

Due to the large differences in the nature of the material. Therefore, the temperature requirements of the two materials are not the same. Generally speaking. The heat resistance of rubber is lower than that of metal materials. (Such as ordinary tires with the ordinary natural rubber.) And high-temperature-resistant special synthetic fibers are mostly made of high-temperature alloy materials. (Such as nylon 66).

4. Different degree of wear resistance

Generally speaking. For the same product. The degree of wear resistance of the two materials is not very different. But if the use of harsh conditions. Then there will be a big difference between the two. For example. Car tires are radial tires. These radial tires use a high abrasion resistance polyurethane compound as the inner liner. Thus greatly improving the service life.

5. Price differences

Due to the cost of raw materials and other factors, the production costs of these two products are also very different. Usually, the price of ordinary plastic is much cheaper than that of cemented carbide. And the production cycle is also much shorter. In addition. Some special occasions (such as) some special mechanical parts (such as) bearings and other parts used in the material is also made of composite materials.
