There are many kinds of anti-static mats, PVC, and all rubber.
First of all, let's first understand what is the anti-static mat? Electrostatic table mats are also known as anti-static mats, anti-static rubber sheets, anti-static rubber sheets, etc. Generally, it is a two-layer structure, the surface layer is a static dissipative layer, and the bottom layer is a conductive layer. Surface layer color: green, gray, blue, black, and there are bright, matt points. The bottom color: black.
Anti-static mats are mainly made of a variety of processes using conductive materials, static dissipative materials and synthetic rubber. Long-lasting use, good acid, alkali and chemical resistance, abrasion resistant and easy to clean. Therefore, the main material of the anti-static mat is rubber. Also known as butyl rubber, butyl rubber is originally a natural semiconductor with anti-static function. Its molecular structure is composed of many carbon chains, which can store a certain amount of static electricity, and can be introduced into the inner layer for a short time to dissipate. The biggest function of the anti-static mat is to store a large amount of static electricity and discharge electricity in an instant. The general life expectancy is about 5 years.
Now PVC is cheap, it can be anti-static because it is added to the production of anti-static agent, this product is a chemical product, it will slowly disappear after 3 to 6 months, and the electrostatic effect is getting worse. After the above comparison, we should know which mat is better. We can distinguish by several methods: resilience, smell, look at the flame, see the gray gravel, see the surface scratches, softness and other methods to identify.
