Hydrocarbon Resin C5/C9 Copolymerization Petroleum Resin

Product introduction:

C5/C9 Copolymerized Petroleum resins is a series of C5 Hydrocarbon Resin
modified C9 Hydrocarbon resin obtained from copolymerizing of C5 fraction and
C9 fraction that derived from the by-product of thermal cracking of naphtha. It
is a granular solid resin with the color range from light yellow to yellow. It
is not a high polymer, but a low polymer with the molecular weight range of
300-3000. C5/C9 petroleum resin has the advantages both of C5 Hydrocarbon resin
and C9 hydrocarbon resin. It has the characteristics of low acid value, good
miscibility, water, ethanol and chemical resistance, the chemical stability
against acid, the good adjustment of viscosity and thermal stability, weather
resistance and light aging resistance because of non-polar groups in its
structure. C5/C9 hydrocarbon resin has good solubility in organic solvents
especially in oil solvent, as well as good compatibility with other resins. It
also has brittle, increasing viscosity, cohesiveness and plasticity. Generally,
it is not used alone, but used as accelerant, regulator and modifier together
with other resins in Adhesive, Rubber, Tire and Coating, etc.

Chemical properties of the C5/C9 Copolymerized Petroleum Hydrocarbon Resins :

Items C5/C9 Copolymerized Petroleum Hydrocarbon Resins
Softening Point(R&B)℃ 85-95 95-105 100-110
Color No.(50% Toluene)Ga. 4# 4#-11# 4#-11#

Recommended Applications:

C5/C9 Copolymerized Petroleum Resins can be used in hot melt adhesives,
adhesives, rubber and tire fields especially in radial tire with the effects of
not only increasing adhesion between particles but also improving adhesion
between particles and cord; in hot melt adhesives, adhesives fields, C5/C9 can
not only provide better initial cohesiveness, but can also be used like rosin
resins to adjust and improve viscosity durability and strength of mixture of
glue and resins.
