الوصف

Gum Rosin, also called colophony or Greek pitch, is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpenecomponents. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperatures. It chiefly consists of different resin acids, especially abietic acid.   

It is the slight yellow or water-white transparent solid, which is made from gum rosin or refined gum rosin through esterification with glycerol; it is a good tackifying resin.
It is soluble in aromatic and aliphatic hydrocarbon solvents, esters, ketones and chlorinated solvents; and with low odor, excellent heat stability and high adhesion. It is compatible with many kinds of polymers,such as NR,CR,SBR,SIS and EVA etc.
