Pentaerythritol Rosin Ester (PR-100S, PR-100LS)

Product Description

Pentaerythritol Rosin Ester (PR-100S) 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.

Characteristics
Excellent tack, internal cohesion
Excellent thermal resistance
Good compatibility with wax, EVA polymers.
Excellent resistance oxidation due to low Abietic Acid contents

Typical Properties
Acid Value (mg KOH/g): 10-20
Softening Point (Ring & Ball, º C): 98-106
Color, Gardner: 3-5

Soluble in: Aromatic and aliphatic hydrocarbon solvents (petroleum benzine, mineral spirit, benzene, ethyl acetate, acetone), esters, ketones and chlorinated solvents.
Insoluble in: Alcohol and water.

Suggested Applications
Mainly used in Ethylene Vinyl Acetate (EVA) hot melt adhesives, pressure sensitive adhesives, as well as rubber compounding, sealants, coatings and other applications.

Forms/Packaging: Flaked or pellet, 25kg net sacks.
Storage: More than six months storage should be avoided due to the potential effect on performance.
