Varieties of Rubbers - HK INDUSTRY

In the industrial sector, rubber sheet is mainly used to protect its use of equipment and devices from corrosion, abrasion and impact. In desulfurization system and water treatment system of thermal power plant, rubber sheets are mainly used to prevent corrosion. While in mining industry, its main function is to protect its equipment and associated piping equipment from abrasion and impact and extend their lives. In culture and education system, rubber sheet is generally used in the printing plate. 

Rubber is a flexible, insulate, impermeable and airtight material processed by latex which is extracted from rubber trees, rubber grass and other plants. It can be divided into natural rubber and synthetic rubber. Natural rubber is made by latex. While synthetic rubber is the result of monomer polymerization. Rubber products are widely used in industrial or all aspects of life. Besides, rubber is the basic material for rubber industry, comprehensively used in the manufacture of tires, hoses, belts, cables, and other various rubber products. It is an important material equivalent to metal, chemical fibers and plastic.   

There are varieties of rubber, including natural rubber (NR), styrene butadiene rubber (SBR), butadiene rubber (BR), nitrile-butadiene rubber (NBR)silicone rubber,  viton rubberethylene-propylene-diene misch-polymere (EPDM) etc. 

Rubber has the following properties: long-range elasticity, showing a high elongation. Good abrasion resistance, high friction coefficient and acid corrosion are other features; some species such as nitrile-butadiene rubber (NBR), fluorine rubber are even oil proof. What's more, rubber has other characteristics such as electrical insulation, eliminating vibration and air tightness. However, it also has demerits, which are poor thermal conductivity, heat - resistant and hard machining.  

Since rubber has a comprehensive application in many products and industries, let's take rubber sheet as an example to see how rubber has made its impact on our production and daily life.  

Rubber sheet takes rubber material as its main body (which may contain fabric, metal sheet and other reinforcing materials), and it's a flaky vulcanized product with a certain thickness and a large area. After the mixed molding paste is rolled or extruded, a flat vulcanizing machine or drum vulcanizing machine will made continuous vulcanization, and that is how rubber sheet is made. Rubber sheet has high hardness, general physical and mechanical properties and can work under pressure and a temperature of 20 ° ~ +140 ℃ air. Its colors are almost cool colors such as black, gray, green, and blue and so on. There is a great variety of rubber sheets including Silicone Rubber Sheet, Hypalon rubber sheet, Chloroprene Rubber Sheet, SBR Rubber Sheet, NBR Rubber Sheet, EPDM Rubber Sheet and Fabric Impression Rubber Sheet.
