Glycerol Rosin Ester G 90L Resin for Diverse Industries and Polymers

Product Name

Glycerol Ester of Gum Rosin, Ester Gum, GEGR

Chemical Properties

Glycerol Rosin Resin Ester, presenting a faint yellow to water-white transparent solid appearance, emerges from the esterification of gum rosin or refined gum rosin with glycerol. This transformative process yields a valuable tackifying resin, widely embraced across various sectors.

A noteworthy rendition of this substance is Glyceryl Rosinate, synonymous with Glycerol Ester of Gum Rosin (GEGR). This particular variant finds its niche in specialized fields, including hot melt adhesives, pressure-sensitive adhesives, adhesive tapes, cosmetics, and depilatory waxes. Beyond its tailored applications, it maintains a robust presence within polymer compositions. EVA, acrylics, polyurethanes, SIS, and SBS polymers all welcome its integration, benefiting from heightened adhesion and refined mechanical attributes.

In essence, Glycerol Rosin Ester stands as a versatile cornerstone, elevating industries and polymer functionalities alike.
