PR-100S

Specifications

Pentaerythritol Rosin Ester (PR-100S) is a light-colored pentaerythritol rosin ester of stabilized gum rosin by hydrogenation.

Pentaerythritol Rosin Ester (PR-100S) is a light-colored pentaerythritol rosin ester of stabilized gum rosin by hydrogenation. It is manufactured to be 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

l    Excellent tack, internal cohesion

l    Excellent thermal resistance

l    Good compatibility with wax, EVA polymers.

l    Excellent resistance oxidation due to low Abietic Acid contents
