ABSTRACT:
A process for producing a porous pipe is disclosed and includes forming an extrudable mixture comprising elastomer particles, binder component and a solid water carrier component having a composition other than the elastomer particles and the binder component and being associated with sufficient water to provide porosity to a porous pipe produced from the mixture; and extruding the extrudable mixture to conditions effective to form the porous pipe.
