The Relationship Between Flow Rate and Mechanical Properties for Polybutylene Terephthalate

摘要

The time required to perform flow rate testing for hygroscopic materials is excessively long. Eliminating the flow rate test by relating the flow rate values with correlations to mechanical runner properties could be a viable solution. Also, the effects of regrind percentage, material dryness, barrel temperature, and residence time on material degradation of unreinforced and 40 % glass filled polybutylene terephthalate have been analyzed.
