CALCIUM SULFATE WHISKERS (CSW) REINFORCEMENT OF POLYMERS - A REVIEW

摘要

Calcium sulfate whiskers (CSW) were patented in 1974. But then the price was too high.In the last 5 years, interest in CSW as reinforcement has grown due to availability and low cost relative to polymers.Surface treated CSW have been found to increase notched Izod impact properties of polypropylene by 60%.CSW increase strength, stiffness and HDT in PA6, PA66 and PBT.CSW improves friction materials based on phenolics, PA66/PVDF blends, and PTFE.
