Resin C9, C5 and C5/C9
resins is a kind of thermal plasticizing resin produced by C5, C9 fraction,
by-products of petroleum cracking, through pretreatment, polymerization and
distillation. It isn't a high polymer bat a low polymer with the molecular
weight between 300-3000. Featared by acid value, easy mutual solubilities,
resistant to water, resistant to ethanol and chemicals. It has the chemical
stabilizing property to acid and alkaline, viscosity adjusting and thermal
stabilizing, Generally, the petroleum resins are not used independently, but
have to be used together with other kinds of resins as promoters, adjusting
agents and modifiers.
testing method of petroleum resins
point: GB2294 coal asphalt softening point determination method, Color:
GB12007.1 color method (toluene:resin=1:1), Acid value:GB2895 unsaturated
polyester resin determination method, Br. value( iodine value): indicator
titration method, Ash content
GB coal asphalt ash content determination method
Properties and functions of petroleum resins in different application areas
mainly use C9 petroleum resins, DCPD resins and C5/C9 copolymerized resins
with high softening points, petroleum resins are added to paints can
increase the final finishes of paints, the adhesiveness of paint films and
the hardness. Resistance to acid and alkaline.
use C5 petroleum resins, C5/C9 copolymerized resins and DCPD resins with low
softening points, these kinds of resins have very good mutual solubilities
with natural rubber particles, No affect to the sulphurization of rubber.
Rubbers added with petroleum resins will increase the strength, adhesiveness
and softening property.
resins have very good adhesiveness, they can increase the adhesiveness of
adhesives, resistance to acid, alkaline and water. Subsequently they will
reduce the production cost.
D printing inks
the C9 petroleum resins and DCPD resins which hare high softening point are
used for printing inks, they hare color spreading, fast dry and brightening
effects and will increase the printing property.
resins have certain unsaturation property and can be used as paper glutting
agents, plastic modifiers etc.
resins are non-hazardous products, however the direct sunshine and rain
shall be avoided daring transportation. They can't be transported together
with self-flammable materials, strong oxidizers and strong acid.
resins shall be stored in dry and cool area, the storage period is one year,
but they can be used again if they out still up to specifications by
inspection after one gear.
