Hi, it is not about the antistatic only... It is about the conductivity and dissipation etc.
Generally speaking, the performance of ESD mats depends on the material from which they are constructed. That material can include: • Homogenous mats are comprised of either vinyl or rubber. These mats typically offer the highest amount of electrical absorption because they are composed of a single, solid block of the same material. • Three-layer mats, usually made with vinyl, offer a decent level of electrical absorption. Their strongest advantage comes in the form of an increased level of comfort to the worker standing on the mat. • Two-layer vinyl mats offer the electrical absorption capabilities of three-layer mats at a significantly reduced cost. • Two-layer rubber mats provide both a high level of electrical absorption and an immense level of comfort to workers. Two-layer rubber mats are also extremely chemical-resistant. However, this multipurpose mat comes at a somewhat higher cost than others. Vinyl mats tend to be preferred in situations where cost is the ultimate priority, whereas rubber mats are better for situations where a high level of chemical or heat resistance is required. With that in mind, it’s likely that many companies will require both vinyl and rubber mats for use in different parts of their manufacturing facilities.
