Anti Static Mats are also known as ESD Mats (Electrically Static Dissipative Mats) and help protect sensitive electronic equipment from damage and explosive chemicals from igniting by dissipating any electrical discharge before it can sabotage the item. Conductive Mats are a special type of anti-static mats which are especially geared to discharging static buildups around the most sensitive equipment and chemicals. All anti-static matting must be used in conjunction with a grounding cord (tied to a proper grounding source) to be effective. Heel grounders and wrist straps are highly recommended for use with anti-static mats for circumventing insulating clothing and shoes. All anti-static ESD mats are tested for proper resistivity during production.
