PENTAERYTHRITOL ESTER
OF MODIFIED GUM ROSIN PR154
OF MODIFIED GUM ROSIN PR154
This range of pentaerythritol esters of modified gum rosin is stabilized to provide excellent thermal resistance and low oxidation tendency.
These resins have been specially designed for hot-melt
applications where high internal cohesion is required.
Resins with lower softening points exhibit good compatibility with natural and synthetic rubbers, EVA polymers, hydrocarbon resins, and waxes. They are soluble in aromatic and aliphatic hydrocarbons, esters, and ketones, and insoluble in water.
