2.Properties and uses:
Pentaerythritol 145# 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
(1). Excellent tack, internal cohesion
(2). Excellent thermal resistance
(3). Good compatibility with wax, EVA polymers.
(4). Excellent resistance oxidation due to low Abietic Acid contents
