PRISM Thermoplastic Rubber (PTR) is a novel, composite rubber material technology principally compounded from EOL, ambient ground, whole tires through the management of a unique process governed by the application of advanced, quantum field physics. The value from this technology is to provide a virgin-material-analog that may be readily integrated at high ratio, into new tire construction using conventional tire chemistry and manufacturing techniques resulting in a sustainable and significant, positive cost-benefit ratio as compared to current tire manufacturing economics.

A rubber composition is based on at least an elastomer, a reinforcing filler, a crosslinking system and a crumb rubber, in which the crumb exhibits a content of sulfur and a content of accelerator such that their sum is less than or equal to 5 parts by weight per 100 parts by weight of elastomer (phr), the said crumb exhibiting a total sulfur content of less than or equal to 4 parts by weight per 100 parts by weight of elastomer (phr) in the composition of the crumb.

A method for reclaiming rubber comprises the steps of: (i) providing a starting material comprising a vulcanized rubber polymer; (ii) subjecting the starting material to mechanical stress and at a temperature of at least 200° C. to achieve at least a partial destruction of the cross-links and the backbone structure of the rubber polymer into fragments; and (iii) reconstituting at least part of the fragments in the presence of a branching/grafting agent to obtain a renewed rubber composition.

The invention relates to a method of producing a polyurethane floor panel, the method comprising mixing rubber powder, a polyol, an isocyanate component and a thermo-selective catalyst for creating a liquid two-component polyurethane reaction mixture, the thermo-selective catalyst being adapted to trigger the reaction of the polyols and the isocyanate into polyurethane selectively in case the temperature of the reaction mixture exceeds an activation temperature of the thermo-selective catalyst stirring the reaction mixture for at least 15 minutes filling the stirred liquid reaction mixture into a mold applying pressure under a temperature that exceeds the activation temperature on the mold and removing the hardened polyurethane floor panel from the mold.
