Rosin-modified glycerol ester resin--No. 138, No. 140
Other Products
138# and 140# are light-colored and stable rosin glycerol esters, developed from rosin as the base material through processes such as decolorization, esterification, and stabilization. They feature high softening points, light color, high viscosity, excellent aging and heat resistance, and good compatibility with polymer materials. They are particularly suitable for industries such as EVA hot melt adhesives and hot melt coatings.
