Surface covering with static control properties

摘要

The present invention relates to a substrate-free conductive surface covering, and a process to manufacture such covering, said surface covering comprising a core layer of sheet particles which are agglomerated and embedded in a polymer matrix, wherein the particles or the polymer matrix, or both, comprise an electrically conductive material.

主权项

1. A substrate-free decorative conductive surface covering, comprising a front surface, a back surface and a core layer of particles of a shredded polymer sheet, said particles being unfused and embedded in a polymer matrix, wherein at least part of said particles are conductive particles comprising an electrically conductive material and being in contact to form in the polymer matrix conductive or dissipative channels for conducting electric charges from the front surface to the back surface of the surface covering; and
wherein the polymer matrix is PVC-based or polyolefin-based.
