Cycle-time reduction of 30% is claimed for a new high-flow PBT from DuPont Engineering Polymers, Wilmington, Del. Aimed at thinwall connectors and large structural housings. Crastin SF is available unfilled and with 15% or 30% glass. Melt viscosity of a 30% glass-filled grade is 43% lower than that of a standard grade at typical molding conditions. DuPont says high flow allows a major reduction in melt temperature and lower hold pressure, as well as faster filling and cooling. Other benefits include the ability to design molds with more cavities and thinner, longer, more intricate flow paths with fewer gates. Mechanical properties are said to be similar to those of standard PBT. For complete properties, visit www. ptonline.com/plaspec. (800) 441-0575 • www.plastics.dupont.com
