Sylvalite RE

Low Color Rosin Esters

Rosin esters impart excellent specific adhesion to a wide range of substrates due to their polarity and polymer compatibility. Their low molecular weight and narrow molecular weight distribution, combined with their cycloaliphatic – aromatic structure, make rosin esters the most broadly compatible of all adhesive tackifiers. They are used in a wide range of polymers including high and low vinyl acetate EVA, acrylics, polyurethanes, SIS and SBS.  Their biorenewable content is 85%.
