PBT Melt-Flow Modification

A company’s plastics R&D team discovered a new use for its Styrene Maleic Anhydride (SMA) resin. SMA 1000 can modify the melt-flow of polybutadiene terephthalate (PBT) in mixtures (in situ), enabling greater flexibility in part design. The new use may lead to thinner, more-complex mold designs, more-intricate flow paths, and fewer gates. Besides improved flow, SMA does not adversely affect the crystallinity percentage of the PBT, nor are inherent properties compromised, such as dimensional and chemical stability. SMA also increases the brittle point and the heat distortion temperature. Mechanical properties are similar to those of standard PBT. Sartomer Co., www.sartomer.com
