| Physical and Chemical Properties | Rosin glyceride, also known as ester gum, is made from Rosin and glycerin after esterification, after vacuum treatment to make irregular transparent block, Flake or granular solid, the lighter the color, the better the quality. It forms a transparent system with high polymers such as NR, CR, EVA, SIS, and SBS in a large proportion range. its relative density is 1.095, softening point is greater than 80 ℃, refractive index is 1.545, acid value is less than 100mgKOH/g, Rosin glyceride is soluble in aromatic and aliphatic hydrocarbon solvents, esters, ketones and chlorinated hydrocarbons, insoluble in water and molecular weight alcohols. Mainly used in adhesive coatings industry. The edible Rosin glyceride is a rosin-based glyceride produced by esterification of refined Gum Rosin and food-grade glycerol, and has a pale yellow transparent solid appearance. Food-grade Rosin glycerides, which meet the national standard GB10287-88 and GB2760-86 of China, can be safely used in food. The edible Rosin glyceride has excellent emulsifying property and viscosity increasing property, which can be used as the base agent of gum to give the gum foam, increase the shape, the chewing resistance and the better taste. |

Rosin ester-glycerol copolymer - Preparation Method
Open Data Verified Data
with special grade Rosin and natural glycerin as raw materials, in the presence of catalyst after esterification and refining. After the rosin was added to the reaction kettle, it was heated to 205-220 ° C., CO2 gas was passed through, zinc oxide was added, and glycerin was slowly added dropwise. After the addition of glycerol, the reaction th was stirred at 220 ° C., heated to 270-280 ° C., and reacted for 3H. When the acid value is below 20mg KOH/g, the moisture and low boiling materials are removed by vacuum, and the finished product can be obtained.

| Overview | glycerol rosin ester, is a modified rosin resin. Modified rosin resin can not only improve the application performance of the product, but also increase the added value of rosin. |
| Main uses | Rosin glyceride is used as the base agent of gum, which endows gum with foaming, plasticizing and chewing resistance, and is used for bubble gum, chewing gum, sugar-free chewing gum, with good taste and oxidation resistance, and to maintain the characteristics of soft, can also be used for chicken and duck animal hair removal, can also be used as emulsion stabilizers in beverages. Rosin glycerides can be used for re-evaluation of wood rosin as a food additive. |
| Technical grade Rosin glyceride | Technical grade Rosin glyceride, because of its polarity and polymer compatibility, most matrices are imparted with excellent specific adhesion. Its low molecular weight characteristics combined with cycloaliphatic and aromatic structure, so that rosin resin can be used as a tackifier compatible with the vast majority of adhesives. Technical grade Rosin glyceride can also be widely used in EVA, acrylic resin, polyurethane, SIS and SBS and other polymers. |
| Application | 1. Hot-melt pressure-sensitive adhesive: Tape adhesive, double-sided adhesive, etc. 2. Solvent heat-sensitive adhesive: laminating adhesive, etc. 3. Hot Melt Adhesive: EVA Hot Melt Adhesive, polyamide Hot Melt Adhesive, etc. 4. Sealing adhesive: building sealant, etc. 5. Solvent pressure-sensitive adhesive: adhesive tape, self-adhesive, etc. 6. Floor glue, etc. |
| Use | for the production of paints |
