Product Description
1. Description
Rosin is light yellow to yellow transparent solid red,softening point 70~90 ºC, the proportion of 1.070 ~ 1.085, solution heat:15.8 kcal/kg,the heat capacity: 0.54 kcal/kg ºC  coefficient of thermal conductivity: 0.11 kcal/m. h.ºC, volume resistivity, 5 x 1016 Ω cm, flash point: 216 ºC.Rosin crystallization characteristics, also easy to produce crystalline phenomenon,there will be a trend of crystallization in organic solvents,such as, the critical temperature about 100 ºC, rosin crystallization melting point of 110 ~ 135 ºC, and difficult to saponification.In addition, rosin with optical activity, rosin than spin control value between 0 ~ 15 ° (best point + 7 °) is the lowest no crystallization and crystallization trend of rosin.
2. Properties 
It is a kind of natural resin, mainly composed of various kinds of resin acids,it can be dissolved easily in many organic solvents,and has special chemical activity.So it is an important raw material for the produc-tion of paper,coatings,inks,rubber,soaps,electronic industrial products,food grade ester gum,rosin ester resins etc.
3. Aapplication 
1), soap industry
Rosin with soda ash and caustic soda cooking together,form a rosin soap.Rosin soap has a great deal of deter
gency, soluble in water,can dissolve grease, easy foaming foam.
Sticky rosin, can make the soap is not easy to crack and rancidity deterioration.

2), paper industry
Rosin used as dipping paper sizing in papermaking industry.Rosin and caustic soda sodium made from rosin soap, rubber, rubber mixed with pulp and adding alum, make rosin does not dissolve in water are attached to the small fiber free acid resin particles, when the pulp drying cylinder rolling heating, rosin softening filling between fiber, this effect is called the "glue" or "glue".Paper, after the "glue" can enhance the water resistance, prevent ink penetration, improve the strength and smoothness, reduce variability.
3), paint coating industry
Resin soluble in organic solvents,and film-forming,luster,is one of the basic material of paint coating.The role
of rosin in the paint is to paint colour and lustre is light,quick drying,paint film is smooth and not easy to fall off.

4), printing ink industry
Rosin in the printing ink is used primarily as a chromatophore, and enhance the adhesion of ink on paper.If no rosin in the printing ink, printing the ink will color glazed into a blur.
5), adhesives industry
With rosin ester and hydrogenated rosin ester as the basic raw material of adhesives, commonly used for hot melt adhesive, pressure sensitive adhesives and rubber tackifier.
6), rubber industry,
Rosin in the rubber industry is used as the softener, can increase its flexibility.Disproportionated rosin potassium soap.
7), electrical industry
65% with 35% rosin with light oil mixture on cable insulating oil used as a protective film, insulation and heat effect.Rosin and bakelite as well as other blended synthetic resin used for insulating varnish
8), building material industry
Rosin in the building material industry is mainly used as foaming agent and concrete floor tile adhesive.Rosin
is used for vinyl chloride asbestos tile adhesive.
Rosin and linseed oil,carbon acid calcium, charcoal, pigments and other mixed together can be manufactured felt ceramic tile.
