The Manufacturing Process Of Food Grade Glycerol Ester Of Rosin

Glycerol Ester Of Rosin also called Ester Gum, the component proportion of food grade is Gum Rosin(90%) + Glycerol Ester(10%), The manufacturing process: from rosin or light-colored rosin by the esterification of glycerol Uses: used in food-grade adhesives, food and other industries Traits: light yellow granular rosin glyceride ester from the rosin and glycerol formed by vacuum processing system Into irregular transparent bulk, flaky or granular solids. And NR, CR, EVA, SIS, SBS and other polymers in a large proportion of the formation of a transparent system. And styrene-butadiene-styrene (SBS), SBR, natural rubber, butyl rubber (EVA), ethylene vinyl acetate, styrene-isoprene-styrene (SIS) Rubber, neoprene, acrylic ester, low molecular weight polyethylene, polypropylene, other non-crystalline polymer, phthalic acid and poly ester plasticizer, alkyd resin, hydrocarbon resin and terpene resin Content. Technical parameters Softening point 85-90 ℃ Acid value mgKOH / g ≤10 Specific gravity 25 ℃ 1.060-1.090 - Light color, low odor, good oxidation and thermal stability, aging resistance, good compatibility with polymer materials NR, CR, SBR, SIS, EVA, etc.), early tack, and can also be used in yellow glue to improve the initial adhesive hot melt pressure-sensitive adhesive, oil-soluble pressure sensitive adhesive, adhesive, Hot melt adhesives, hot melt adhesives, polyamide hot melt adhesives, sealants, varnishes, adhesives, pipe glue Recommended use: used in the manufacture of laminating adhesive, decorative adhesive, label adhesive, adhesive tape, hot melt adhesive, sanitary napkin, Adhesive, EVA Hot Melt Adhesive, Polyamide Hot Melt Adhesive, Sealant, Varnish Paint, Binding Adhesive, Pipe Adhesive. Soluble in: aromatic and aliphatic hydrocarbon solvents (petroleum gasoline, mineral spirit, benzene, ethyl acetate, acetone), esters, ketones and chlorinated hydrocarbons. Insoluble in: ethanol and water.
