Abstract: The application discloses coherent, processable rubber compositions containing cured rubber particles, especially recycled crumb rubber, dispersed in a curable base rubber. A processable composition, particularly one which can be roll-processed into a self-sustaining web is achieved by including in the curable rubber a low-viscosity curable rubber component such as a liquid rubber. This component wets the crumb rubber enabling it to disperse fully during mixing and connect intimately into the structure upon curing. This technique enables larger quantities and/or smaller particle sizes of the crumb rubber to be successfully incorporated while maintaining processability. Inert fillers can be used or omitted, reducing density. The novel rubber compounds are particularly suitable for making into layer products such as mats and flooring materials. Desirably these are laminated with fabric such as tufted textiles. This can be done in a compression moulding process.
