Exogenous addition was used to conduct a model study on the effect of certain heavy metal ions on the stability and vulcanization efficiency of uncompounded and compounded high-ammonia natural rubber (HANR) latex, which was then measured using a Brookfield viscometer, mechanical stability time (MST) tester, and tensile testing machine. The case of pre-vulcanized HANR latex … Continue reading A Model Study on the Impact of Metal Ions on Pre-vulcanization of Concentrated Natural Rubber Latex and Dipped-Products
