WebSep 13, 2024 · 2 – Synthetic Rubber PSAs. Synthetic rubber-based pressure sensitive adhesives contain styrene-butadiene (SBR), or a styrenic block copolymer (SBC) like polystyrene-polyisoprene-polystyrene (SIS) or polystyrene-polybutadiene-polystyrene (SBS). These PSAs also contain a tackifying resin. SBR PSAs have better heat-aging properties … WebISOLUTE® PSA is an ethylenediamine-n-propyl bonded sorbent sorbent used for the extraction of strongly acidic compounds (e.g. those containing sulfonic acid groups) or analytes unstable under acidic conditions, from aqueous samples using a weak anion exchange retention mechanism. It can also be used to complex with certain metal cations.
