Styrenated-terpene Resin

It is a light-colored pentaerythritol rosin ester of stabilized gum rosin by hydrogenation. It is used as a tackifier in adhesives industry. It provides excellent heat and aging stability, improved resistance to oxidation, polymer compatibility, good skinning resistance and better retention of color. Mainly used in hot melt adhesives and pressure sensitive adhesives. Characteristics Excellent tack, internal cohesion Excellent thermal resistance Good compatibility with wax, EVA polymers. Excellent resistance oxidation due to low Abietic Acid contentsSpecifications and Applications Item UnitSoftening Point (Ring & Ball), ºCColor, Gardner,#Acid Value(mg KOH/g)FeaturesApplicationsTest methodGB8146GB/T 1722-1992GB8146PR-100S98-1063-510-20Light color, high viscosity, good heat resistance, compatible with many kinds of macromolecular polymers, improve the cohesion of EVA adhesive greatly.EVA based hot-melt adhesive, hot-melt pressure sensitive adhesive, hot-melt coating, gum base, phenolic varnish, bookbinding adhesive, carpenter's glue, etc.PR-100LS100-108≤120-30Light color, low odor, good heat stability, and excellent compatibility with macromolecular polymers.Hot-melt adhesive, sanitary adhesive, structural adhesive, packing adhesive, cigarette gum base, sealant, complex film adhesive Soluble in: aromatic and aliphatic hydrocarbon solvents (petroleum benzine, mineral spirit, benzene, ethyl acetate, acetone), esters, ketones and chlorinated hydrocarbons.
