There are a variety of products that are related to the hydrocarbon resin actually. But, you are only familiar with the products. As to the hydrocarbon resin or petrolum resin, common users will have few acknowledge or interest actually. Well, the petroleum resin occupies large proportion. The petroleum can be devided into 3 aspects, aliphatic series, aromatic series, copolymerization series and dicyclopentadiene and so forth. In other words, you can call them C5 resin, C9 resin, C5/C9 resin and DCPD resin respectively.
How much do you know about C5 resin? It is a kind of thermoplastic resin with relatively low molecular mass that is ranging from 1000 to 3000 while the color will different from yellow to sandy beige. The C5 resin can be used to improve the viscosity coefficient perfectly and can be dissolved into benzene, methylbenzene and dimethylbenzene. There are two softening point series, 80-110℃, and 110-160℃.
The color of C9 resin is different from pale yellow to deep brown and the softening point is different from 80℃ to 130℃. The density of the resin is 1.069/cm3 and the inflammation point is about 260℃. It is waterproof and weather-proof and light-proof. The excellent intermiscibility paves the way for good dissolubility, plasticity and agglutinating value. Well, just as its name implies, the C5/C9 resin is the combination that enjoys the virtues of both C5 and C9 resin.
The dicyclopentadiene resin will come into being relying on the splitting decomposition of petroleum, which can be regarded as the byproduct of petroleum decomposition. Although it lacks stability, this kind of resin has high degree of unsaturation and good thermal reaction property. According to different chemical graft modification technique, it is important material that can manufacture other top-grade resins. Terpene resin is popular too and it can be widely used to adhesives like natural rubber, SBR rubber and crylic acid because of its good compatibleness, stability and inoxidizability and tackiness.
