An easy method to help identify high temperature resistant antistatic table mats
Customers often come into contact with high-temperature heat sources on anti-static work surfaces, such as contact with high-temperature heat sources such as anti-static thermoelectric welding, alcohol lamps, hot air guns, etc. In order to improve production safety, a method that can effectively prevent static electricity accumulation and An antistatic mat that can safely discharge static electricity and avoid disasters caused by high temperature sources. Therefore, the requirements of such special occasions naturally put forward the requirements of high temperature resistant antistatic mats. But at present, many manufacturers claim that anti-static table mats are high temperature resistant. How to identify which type of anti-static mat is high temperature resistant? ESD technical advice recommends a simpler identification method.
Before talking about the identification method, it is helpful to understand and identify the material of the high temperature resistant antistatic table mat. The high temperature resistance of the antistatic table mat is one of the physical properties of the material, and it has a relationship with the raw materials and manufacturing process of the antistatic table mat. The more common anti-static mats on the market are rubber materials, rubber materials, and PVC materials. In general, we recommend the use of rubber antistatic table mats. Its high temperature resistance, low temperature resistance, oil resistance, chemical resistance, tensile strength, tear strength and other physical properties are better than the other two materials. All of them are much better.
Having said all this, in fact, the identification method is very simple. Use a burning cigarette end with a cigarette core temperature above 800 degrees Celsius to contact the surface of the anti-static table mat. You can see the result in 10-20 seconds. If there are no obvious hot marks, no melting points, or only a little black to wipe, generally an antistatic table mat made of a better rubber material, the high temperature performance is relatively guaranteed; if there are pits or melting Point, the material is likely to be rubber and plastic, especially PVC, and its high temperature resistance is much worse. This kind of rubber-plastic or PVC anti-static table mat, once a fire disaster occurs, its flame retardancy is generally poor, and it will also release harmful gases. Therefore, many customers often put forward requirements for the flame-retardant performance of this anti-static table mat. I won't talk about it here.
