Glycerol Ester Resin is obtained by esterifying the natural resin, Kolofon Resin, with glycerol alcohol at high temperatures.

Glycerol Ester Resin is a stabilized product to provide excellent thermal resistance and resistance to oxidation. Compared to Kolofon Resin, it has higher thermal resistance, lower acidity, a higher softening point, and provides high adhesion quality in many areas.

It is a light yellow solid resin compatible with the most common compounds such as EVA polymers, SIS, SBR, natural rubber, butyl rubber, hydrocarbon and terpene resins, and other polymers.

Glycerol Ester Resins are soluble in aromatic and aliphatic hydrocarbon solvents, esters, and ketones.

It is sold in original pallets of 1,000 kg / 1,200 kg and in 20 kg / 25 kg bags, in the form of glass shards.

Rosin resin is obtained by esterifying an organic compound, pentaerythritol, with a similar resin.

Several different types of product are available depending on their softening point (90-degree softening, 100-degree softening Penta Ester Resin).

Penta Ester Resin, stabilized to provide excellent thermal resistance and resistance to oxidation, is compatible with the most common materials such as EVA polymers, SIS, SBR, natural rubber, butyl rubber, hydrocarbon and terpene resins.

These resins are soluble in aromatic and aliphatic hydrocarbon solvents, esters, and ketones.

These resins are insoluble in ethanol and water.

It is sold in original pallets of 1,000 kg / 1,200 kg and in 20 kg / 25 kg bags, in the form of glass shards.
