For the big jobs in polypropylene, the pros use Pro-fax. In critical film and fiber operations, where high-volume, low-cost production hinges on resin quality, Pro-fax is the outstanding favorite—far ahead in performance and in sales.

SERIES For the big jobs in plastics, the pros know there's a right Pro-fax formulation for every injection molding and extru sion need. Hercules—first in all phases of polypropylene manufacture and de velopment—continues to be first with new resins for special requirements. Now you can use polypropylene for the big jobs requiring extra-high impact at low temperatures. This new Pro-fax co polymer series was especially developed for luggage, totes, and large housings for automotive, appliance, and industrial use. It molds as readily and steadily as general-purpose Pro-fax polypropylene. Parts made with Pro-fax 8000 match or exceed the low-temperature perform ance of polyethylene and the alloys at -20°£—provide far superior heat re sistance, surface hardness and rigidity.
