Surface Covering Product and a Method for Preparing the Same

A surface covering product, characterized by comprising:

• a surface ornamental layer (110) with a top surface and a bottom surface;
• a buffer layer (105) with a top surface and a bottom surface;
• a supporting layer (106) made from a foamed polymeric material with a top surface and a bottom surface;
• and
• a backing layer (109) with a top surface and a bottom surface;
• wherein the bottom surface of the surface ornamental layer (110) is attached to the upper surface of the buffer layer (105), the bottom surface of the buffer layer (105) is attached to the top surface of the supporting layer (106), and the bottom surface of the supporting layer (106) is attached to the top surface of the backing layer (109).

A supporting layer of a surface covering product, characterized in that the supporting layer is made of a rigid foamed polymeric material, wherein the rigid foamed polymeric material comprises:

• a polymeric material 100 phr;
