Do you really know "rubber and rubber sheets"?
Whether it is rubber or rubber sheet, you must be familiar with the name, but many people don't know what they really are. Learn about rubber and rubber sheets with rubber sheet manufacturers! Here is the most comprehensive knowledge about rubber and rubber sheets.
What is Rubber?
Rubber refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature, can produce large deformation under the action of a small external force, and can return to its original shape after removing the external force. Rubber is a completely amorphous polymer.
History of Rubber
According to literature records, the Mayans used rubber to make shoes; some indigenous people in Brazil used rubber to make waterproof fabrics; and after rubber was introduced to the United Kingdom, everyone found that this material can effectively wipe away the marks left by pencils. So, rubber is also used to describe eraser.
Classification of Rubber
Rubber is roughly divided into three categories: natural rubber, synthetic rubber, and recycled rubber.
1. Natural rubber
Natural rubber refers to the elastic solid material made of natural latex collected from rubber trees and processed through coagulation and drying. Expensive, excellent comprehensive physical and mechanical properties.
2. Synthetic rubber
Refers to rubber synthesized by chemical methods to distinguish it from natural rubber produced from rubber trees.
3. Recycled/reclaimed rubber
Recycled rubber refers to waste vulcanized rubber and scraps of vulcanized products. After physical and chemical processes such as pulverization, processing, and mechanical treatment, it changes from an elastic state to a plastic and viscous material that can be re-vulcanized. Rubber material. Recycled rubber is the most common raw material for rubber sheets.
Regarding the glue content:
The density of pure rubber (natural rubber and synthetic rubber) is about 1. Each time the same material (auxiliary material) is filled, the density will increase a little, and the rubber content will decrease a little. Generally speaking, the same rubber, with a small specific gravity, has a high rubber content and high performance.
What is a Rubber sheet?
Rubber sheet/rubber slab refers to a sheet-like product with a certain thickness and a large area obtained by vulcanization with rubber as the main material (which may contain reinforcing materials such as fabric and metal sheet).
Keywords: rubber sheet, rubber plate, rubber pad, rubber slab, rubber board
Classification of Rubber Sheets
There are many classifications of Rubber sheets, such as: styrene-butadiene rubber sheet, nitrile rubber sheet, nitrile rubber sheet, EPDM sheet, natural rubber sheet, natural rubber sheet, silicone sheet, silicone foam sheet, insulation There are about twenty categories of rubber sheets and so on.
