NEW WATER IMPELLER MADE FROM HIGH-STRENGTH AROMATIC NYLON HELPS WASHING MACHINES WORK HARDER & LONGER
More than a decade ago Alliance Laundry Systems LLC, one of the world's largest manufacturers of commercial laundry equipment, faced a classic dilemma. The lifespan of its durable, Goliath-like washing machines was being threatened by the mechanical equivalent of David's slingshot. The culprit? A three-inch impeller in the water pump that helps push dirty water and debris out of the machine and down the drain was failing. Chemicals and detergents, heat from belt friction, and hot wash water were causing the impeller to wear out long before the 15 to 20-year lifespan of the average washing machine. The solution: AMODEL AT-1125 HS polyphthalamide (PPA) manufactured by Solvay Advanced Polymers, L.L.C. This 25 percent glass-reinforced aromatic nylon is designed for applications requiring high stiffness, excellent dimensional stability, and resistance to heat and chemicals. "AMODEL PPA performs well in the extreme environments typically associated with commercial laundering," said Chris Scarazzo, a market development manager for Solvay Advanced Polymers. "This includes repeated exposure to hot water, chemicals, detergents, bleaches, and fabric softeners as well as the dirt and debris found on dirty clothes." Impellers molded from AMODEL PPA and installed in machines more than a decade ago are still performing without any cracking or breaking. According to Scarazzo, "That's a performance record that commercial laundry manufacturers have come to rely on." http://www.solvayadvancedpolymers.com
