5 AMERIPOL POLYMERS NOW AVAILABLE IN CRUMB FORM Ameripol 1511, a cold polymerized type, is now avail able in crumb form. Including the hot polymerized types Ameripol 1006, 1009, 1012, and 1013, this now makes five polymers available both in bale or crumb form. Crumb rubber is not compressed; thus retains the porous nature of the rubber particles as they are coagulated. The crumbs can be dissolved very easily in a suitable solvent since the solution speed is directly proportional to the amount of exposed area. In making products such as cement, where the rub

ber must be put into solution, use of crumb rubber saves considerable time and expense. Ameripol crumb type polymers eliminate the need for milling and cutting or pelletizing equipment as part of a solution process. A simple agitated vessel can be used for dissolving the rubber. Packaging of the I material is in rec t a n g u l a r cartons h o l d i n g approxi mately 60 pounds. |
TWO NEW AMERIPOL MICRO-BLACKS REDUCE FABRICATION COSTS Ameripol 4758 and Ameripol 4772 are two new additions to the line of Ameripol MICRO^BLACKS. These masterbatches offer excellent dispersion of carbon black in the latex, obtained by high shear mixing. Both types are highly oil-extend ed; thus offering a lower per-pound cost to the fabricator. Yet physical properties are very attractive as a result of the extremely fine dis persion exclusive with Ameripol MICRO-BLACK. Both masterbatches are suitable for products requiring good abrasion resistance.
ACCENT ON SERVICE SPEEDS BUTADIENE SHIPMENTS These new barges, operated by Goodrich.-Gulf on inland waterways, are believed to be the first designed specifically for butadiene service. Goodrich-Gulf h a s previously shipped buta diene by ocean barge to o v e r s e a s customers. This new transportation system will substan tially improve service to butadiene customers in the Midwest. Leased storage facilities will increase inventory available to users. In synthetic rubber, too, Goodrich-Gulf offers fast shipments from strategically located ware house stocks in Chicago, Akron, Newark, and Neosho, Missouri; backed by giant plants in Institute, West Virginia, and Port Neches, Tex. Most rubber product manufacturers are with in a 24-hour delivery range of Ameripol stocks.
