LIR Isoprene rubber Kuraray Rubber - Elastomer >> Polyisoprene rubber, IR ADHESIVE >> Water-based ADHESIVE >> Hot-melt SEALANT LIR is a viscous liquid rubber based on isoprene, which was originally synthesized by Kuraray Co., Ltd. LIR is colorless, transparent and almost completely odorless. LIR has a function as a "Reactive plasticizer". In terms of funciton as a "Plasticizer", LIR is the rubber with the highest molecular weight among materials which habe the plasticizing function. In terms of function as a "Reactive", it is "vulcanizable". LIR is co-vulcanizable with solid rubber such as NR, SBR, BR and EPDM using sulfur or peroxide. LIR is crosslinkable by reaction of its functional groups using metal compounds, epoxy compounds, isocyanate compounds, amine compounds and is crosslinkable by UV radiation. Adhesives : solution, hot-melt, cross-link, latex Sealents : automotive, construction Viscous liquid rubber based on isoprene. Used in adhesives and sealants. Can be used as a reactive plasticizer. Co-vulcanizes with solid rubber such as NR, SBR, BR and EPDM using sulfur or peroxide. Crosslinks by reaction of its functional groups using metal compounds, epoxy compounds, isocyanate compounds, amine compounds and by UV radiation. Applications : adhesives (solution, hot-melt, crosslink, latex) and sealants (automobile, construction).
