Petroleum Resin
(A). Description:Petroleum 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.(B). Properties and functions of petroleum resins in different application areas1. PaintsPaints 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.2. RubbersMainly 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.3. AdhesivesPetroleum 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.4. Printing inksUsually, 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.5. OthersPetroleum resins have certain unsaturation property and can be used as paper glutting agents, plastic modifiers etc.Petroleum 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.(C).
