General
-
Gum
Rosin is Natural organic compound, mainly composed of resins, possesses
chemical activity when dissolved in many organic solvents.
-
Gum
Rosin is easily softened and oxidized, in the oil paint industry, the
carboxylation reaction of resin acid is usually employed to produce
resinate for further use
-
It is
kind of natural resin, a mixture with various organic acid, and with
special chemical activity, and important chemicals.
Process
-
While
in the producing of synthetic rubber and printing ink, polymerized
rosin, resin acid is changed intodisproportionate rosin, hydrogenated
rosin, etc for further use by its double bond reaction.
-
Packing, Storing and Transporting of Gum Rosin can be done in galvanized
Iron drums of about 225 / 230kgs net each, 225kg gi drum.
-
Gum
Rosin is distilled from pine resin.
-
The
wood for distillation of resinous wood generally used is obtained from
longleaf and slash pine species. Live- trees of these species are also
tapped for the oleoresin from which gum turpentine and rosin are
obtained.
-
Changes in the composition of gum rosin during disproportionation in the
presence of 5% palladium-on-charcoal have been determined by gas
chromatography.
Uses
-
Gum
Rosin used in , paint, most rosin product is used for the manufacturing
of paper, soap and printing ink.
-
A gum
rosin ester modified by pharmaceutical glycerin, specially made for the
application of chewing/bubble gum base, citrus oil beverages and
flavors.
-
Rosin
Ester is used as emulsion agent.
-
Blend
of plant oils and gum rosin used for the impregnation and protection of
stone and masonry.
Market
-
The
risk of gum rosin production for the producers is large. It takes one
month for producers to purchase oleoresin, the raw material to the
produce and transport rosin, the final product to ports for sale.
-
Chinese gum turpentine industry is always a subsidiary industry of gum
rosin.
-
The
price of gum turpentine changes frequently, and it has been in an
increasing trend in recent years.
