The static-control properties of a well-designed ESD flooring material should last as long as the floor. In high-performance, permanently protective ESD floors, elemental conductive or dissipative materials, such as carbon and graphite, are embedded in the manufacturing process. Assuming the additives are bonded to the material in adequate concentration, and the fibers or filaments are exposed—creating an electrical bond with the shoe soles of people walking on the floor or with objects such as rolling carts or ESD chairs—the material should dissipate static throughout the life of the floor.
Finishes and Some Flooring Materials Lose Conductivity Over Time
ESD waxes and finishes wear off, providing temporary static protection that can’t be evaluated without routine testing with an ohms meter. Other materials, such as static-dissipative rubber, lose their effectiveness over time due to the chemical makeup of the flooring material. In tests conducted by ATT, static-dissipative rubber lost its conductivity after seven years. By comparison, electrically conductive (EC) rubber made with carbon chips retains its conductivity permanently.
All ESD Floors Must Be Properly Cleaned and Maintained
To perform effectively, all ESD floors must be properly cleaned and maintained. A layer of dirt and debris will act as an insulator, diminishing the performance of any ESD floor. Generic floor waxes contain static-generating polymer emulsions that also hinder performance. Common sense should be all that’s necessary to keep a well-designed ESD floor performing at optimal effectiveness throughout the life of the installation.
