Rosin is a kind of natural resin, which is mainly composed of various resin acids. It is easily soluble in a variety of solvents and has unique chemical activity. It is an important raw material for papermaking, coating, ink, rubber, soap, electronics, edible ester, rosin ester resin and other industries.
Amorphous rosin is a light yellow transparent solid obtained by treating rosin through a specific process. It improves the anti crystallization performance, has good heat resistance and aging resistance, and has good compatibility with polymer materials. It is a good tackifying resin.
