How to Distinguish Between Good and Bad ESD Table Mats
Anti-static table mats are mainly made of anti-static (conductive) materials, dissipative materials, and synthetic rubber. They have a matte finish and a light diffusion rate of over 95%.
ESD table mats are also known as anti-static desk mats, anti-static rubber sheets, and anti-static rubber sheets. They generally have a two-layer structure: a surface layer for dissipating static electricity and a bottom layer for conducting static electricity. Surface layer colors include green, gray, blue, and black, and they come in glossy and matte finishes. The bottom layer is black.
ESD table mats are mainly made of conductive materials, dissipative materials, and synthetic rubber through various processes. They are durable, have excellent resistance to acids, alkalis, and chemical solvents, and are wear-resistant and easy to clean.
Therefore, it is evident that the main material of anti-ESD table mats is rubber, also called nitrile rubber. Nitrile rubber is a natural semiconductor with anti-static properties. Its molecular structure consists of many carbon chains, capable of storing a certain amount of static electricity, which can be dissipated into the inner layer in a very short time. The main function of an anti-ESD table mat is to instantly store a large amount of static electricity and conduct it through discharge. Its lifespan is generally around 5 years.
PVC is currently inexpensive. Its anti-static properties are due to the addition of anti-static agents during production. This type of product is a chemical, and its effectiveness gradually diminishes over 3 to 6 months, leading to a decreasing anti-static effect.
Based on the above comparison, we should know which table mat is better. We can distinguish them using several methods: resilience, smell, observing flames, examining ash, checking surface scratches, and assessing softness.
Our company's anti-static table mats are of high quality, meet national standards, and have a shelf life of 5 years.
