TORONTO — BASF Corp. resins figured prominently in the two winning entries for SPE's 1997 Plastics Industrial Product Design Award.
An Ultradur B, 10 percent glass-reinforced thermoplastic polyester is used to injection mold the vessel in the PF/2 Energizer, a water-efficient toilet flushing system that can be retrofitted into standard vitreous china toilet tanks.
The PF/2 Energizer harnesses water-line pressure to pressurize a dome of air in the vessel. During flushing, the pressurized air forces water into the toilet bowl with a strong flushing action, allowing the use of less water. W/C Technology Corp. of Troy, Mich., developed the PF/2 Energizer, which uses less than 1.6 gallons of water per flush. Flambeau Corp. of Baraboo, Wis., injection molds the vessel components.
Kimball International's Purpose Seating Office Chair uses parts made of a glass-fiber-reinforced and impact-modified Ultramid nylon 6 supplied by BASF. The Jasper, Ind., firm chose the resin for the chair's main structural component, a one-piece seat and back shell. The shell has a ribbed channel to increase load-bearing strength while maintaining some flexibility.
Lescoa Inc. of Grand Rapids, Mich., injection molds the shell. The design consolidates parts and effectively distributes stress loads while the user turns or twists in the chair.
Krauss-Maffei Corp. and SPE's product design and development division sponsored the awards, which included a $2,500 honorarium and an acrylic plaque for each winner.
