Detailed explanation of the characteristics of anti-static rubber mat
Anti-static rubber mat is also called esd mat, anti-static table pad, etc. It is mainly made by mixing anti-static agent, conductive carbon fiber and rubber through a special process. The finished anti-static rubber is generally divided into upper and lower layers. There are various types of anti-static rubber.
One is PVC anti-static mat. The surface of this mat is smooth and shiny, but it has poor flexibility. The advantage is that it is cheap, has good abrasion resistance, acid and alkali resistance, and solvent resistance, and is easy to clean. It is also obvious that it is too hard, has poor high temperature resistance, and has a short service life, generally only 3-6 months. After that, the antistatic agent will slowly volatilize until it disappears, and the antistatic performance will also disappear. This PVC antistatic There are relatively few applications of electrostatic rubber on the market.
There is also a rubber-type anti-static rubber, which is made of modified PVC and synthetic rubber as the main materials. The surface has the texture of rubber. It can be divided into two types: bright and matt. Compared with PVC anti-static rubber , Its softness and elasticity are better, the price is higher, but the cost performance is better, so it is widely used in the market.
Another type of anti-static rubber sheet is also called anti-static rubber sheet. Although it is also rubber, this rubber is nitrile rubber, also called natural rubber. It is a natural semiconductor and has anti-static properties. The structure is composed of countless carbon chains. The carbon chains store a certain amount of static electricity, so the static electricity generated on the rubber surface will be quickly introduced into the inner layer and dissipated, and the residual static electricity will enter the earth smoothly through the conductive layer.
