Abstract (en)
[origin: US4307552A] For obtaining a roofing element of the slate type, a synthetic material such as polyethylene, polypropylene or polyvinylchloride is mixed with a charge, such as chalk, kaolin, dolomite, talc, and with carbon black. The proportion by weight of synthetic material is between 30 and 60%, whereas that of the charge is between 20 and 60% and that of the carbon black is between 0.5 and 5%. The mixture is extruded and then calendered.
