Conductive floor coverings made of conductive coated chips showa defin itely better and long lasting performance. Conductive coated chips are forming a solid , homogeneous compound which is stable in size anddimensions, a far better solution than "liquid" chemical additives like antistatic surfactants. This is the reason why the electrical properties of tiles are constant, permanent and not influenced by either ambient humidity or aging of the product. This is a most important selectioncriterion, considering that the properties of a floor covering are required to be permanent and thatperformance to specifications will be subject to regular inspection.
