Comparison of the Performance of Vulcanized Rubbers and Elastomer/TPE/lron Composites for Less Lethal Ammunition Applications

摘要

One of the exciting novel potential applications of thermoplastic elastomers (TPEs) is less-lethal ammunition (LLA).The importance of LLA in crowd control and law enforcement has been acknowledged,and became evident for air marshals after the September 11,2001 crisis.This article will compare the dynamic mechanical behavior of various elastomer/TPE/iron composites and commercially available LLA based on conventional cured rubbers (ethytene-propytene-diene rubber [EPDM],styrene-butadiene rubber [SBR],and natural rubber [NR]).Optimum combination of properties for LLA application was shown by the pdy(sty-rene-b-isobutytene-to-styrene) (SIBS)/butyl elastomer (MR)/ iron 50/50/233 composite.
