pentaerythritol rosin ester

used as a tackifier in adhesives industry. It provides excellent heat and aging stability, improved resistance to oxidation

HAIPENTA 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 contents
