<p>Material for flooring in cars consists of complex multilayer structure in which all constituents are selected from the family of synthetic polymers based on polyolefins, most particularly those based on polyethylene. Material for flooring in cars consists of complex multilayer structure comprising interior layer which is in contact with floor car and which acts as shock and sound absorber covered with surface layer which has a high resistance to scratching, the two layers being bound to one another; all said constituents being selected from the family of synthetic polymers based on polyolefins, most particularly those based on polyethylene; the surface layer consisting of composition comprising mixture of high and low density polyethylenes, ethylene vinyl acetate and fillers; supporting layer, in contact with floor, is based on densely filled low density polyethylene; and the association of the two layers is carried out by complexation during extrusion of surface sheet, said complexation being carried out by squeezing said sheet while it is at a high temperature. An Independent claim is also included for method for making said material.</p> |
