Advancion is a leading global producer of IPHA (N-Isopropylhydroxylamine), a highly efficient free-radical scavenger commonly used to shortstop emulsion styrene-butadiene in the production of styrene-butadiene rubber (SBR) and acrylonitrile-butadiene polymerization reactions in acrylonitrilebutadiene rubber (NBR) elastomers. IPHA is an excellent multipurpose shortstop that can be used alone to provide both excellent Mooney viscosity control and effective popcorn polymer prevention.
IPHA is ideal for use in the worldwide production of rubber products that are compliant with the Nitrosamine Regulation TRGS 552 (Technische Regeln fur Gefahrstoffe-Technical rules for hazardous substances) in Germany. IPHA can also be used to effectively shortstop other commonly used free-radical processes, such as suspension polymerization of vinyl chloride and emulsion polymerizations of chloroprene and fluorinated olefins.

DID YOU KNOW?
Traditional shortstop systems normally consist of two components: a non-volatile product to provide Mooney viscosity control and a volatile product to prevent popcorn polymer formation in monomer recovery areas. Because of its unique physical properties, CHAINGUARD™ I-15 partitions almost equally between the latex and vapor phases during monomer recovery, providing excellent control in both phases.
