Can graulated,or powdered, vulcanized tire rubber be extrusion molded successfully?

Per Tom Cunningham

To my knowledge this is a fully crossed linked material which will not
melt. Therefore melt processing is not available. I have read about some
chemical processes somewhere which can convert this material. Also there
is a twin screw process available which can convert large particles into
fine particles suitable for use as a filler.

Yes, but you need a lot of additives to modify it's flow properties, including compatilizers for the additives you use. FORD is in trouble over this - by making a commitment to it's shareholders that they will find a use (other than roadway re-surfacing) for the FIRESTONE tires it has (that FIRESTONE won't take back - 'cause FORD broke off their relationship.

However, FORD won't pay the price for a "good" thermoplactic modified polymer. Purportedly, they mak be making some headway in Europe, only because Europe has always been into tire recyling.
