TYPE: RC-GJR2090～2120

Product profile:

  RC-GJR2090~2120 is a sort of thermoplastic resin with light yellow granular solid  it is a thermoplastic resin produced mainly through carbon 5 and carbon 9 fractions which is from thylene unitas raw material,, it is a polymer with low molecular weight. Under the action of catalyst and certain temperature and pressure condition, it is produced by polymerization reaction through special production technology.

  This petroleum resin has good compatibility with natural rubber(NR), synthetic rubber, styrene polymer(such as SIS, SBS, SEBS, EVA) and so no. And also it is good compatible to natural viscosity resin (for example terpenes rosin and its derivative). Except that, C5/C9 copolymerized petroleum resin has the advantages of both C5 petroleum-resin and C9 petroleum-resin.

Product features:

1.Low acid value, good compatibility, and resistance of water, alcohol and chemicals and so on are also its characteristics. It has chemical stability for acid-bases, and it can adjust viscosity and has good thermostability.

2.As no polar gene contained in structure, so it has good water resistance, acid-bases resistance and climatic resistance and light-proof aging. It has good solubility in organic solvent, especially in petroleum solvent, and what’r more, it has good compatibility with other resins, and has a certain fragility, viscosifying capacity, cohesiveness and plasticity. Generally speaking, it isn’t used independently, but to be used as accelerant, conditioning agent and modifier with other resins.           

Products specifications:

Purpose:

1.C5/C9 copolymerized petroleum resin gradually takes the place of expensive C5 petroleum resin in the field of hot melt adhesive, adhesive agent, tackiness agent, and rubber and tires, it is accepted by customers both domestic and overseas. When putting copolymerized petroleum resin in rubber and tire filed, not only cohesive force among colloidal particles can be enlarged, but the cohesive force between colloidal particle and cord can also be increased, which applies to rubber products with high-demanding like radial tire and so on.

2.Meanwhile, in the field of adhesive agent, tackiness agent etc, C5/C9 copolymerized petroleum resin can not only provide better initial viscosity, but also can adjust durability and bonding strength of the mixture viscosity between glue and resin, just like abietic resin.
