HOW BARRETT PHTHALIC ANHYDRIDE HELPS
RAISE PRODUCTION RATES and MANUFACTURING COSTS
LOWER
Resin manufacturers appreciate the operating economies t h a t are made possible through t h e use of Barrett phthalic anhydride. Barrett phthalic anhydride is available in 5-ply paper bags which assure adequate protection. The uniform weight of 80 lbs. in each bag may be used as the unit in formulation, and the phthalic anhydride can be fed directly into the processing equipment, thus cutting time of weighing or measuring. Handling and mixing are facilitated because the convenient-sized flakes are smooth flowing, and contain a minimum of fines. Moreover, Barrett phthalic anhydride is free from materials which cause premature gelling and foaming, and has a uniformly low maleic anhydride content which permits setting up formulae which do not require adjustments for varying maleic content. Barrett phthalic anhydride is manufactured at two modern, strategically located plants which employ the most up-to-date technological advances and the newest type equipment.
