C5/C9 of petroleum resins

Petroleum resins are very widely used, it has better solubility with natural rubber, it can also be used as a modifier in addition. Petroleum resin is derived from petroleum, thermoplastics, high aromatic hydrocarbons, non-reactive hydrocarbon resin. Polymerization catalyst usually made of aluminium trichloride, boron fluoride or sulfate (see acid-base catalyst), polymerization temperature 0~100℃. According to the different polymerization conditions, petroleum resin have different softening points ranged from viscous to solid state, color from pale yellow, amber to black, relative density is (15) 0.98~1.06, refractive index is 1.53~1.60.

Petroleum resins have good of mixed dissolve property with synthetic rubber and the other synthetic resin. softening points of 30~60℃ of petroleum resin is used as stick agent or dhesive of synthetic rubber and natural rubber, softening points of 60~130℃ petroleum resin is used as incremental agent of printing ink, as well as paper of rubber material, waterproof cloth of waterproof agent, etc. The raw materials of petroleum resins are rich, the production cost is low, but it has wide range of uses.

In recent years, China's carbon five (C5) petroleum resins industry is rapidly developed, both production capacity and technology are developing by leaps and bounds. According to statistics from CMS information, the production capacity of C5 petroleum resin is from 300,000 tons to 500,000 tons in 2011, and there are still many enterprises in production or expansion.

The exports of petroleum resin 16394 tons in March, and our country has become a petroleum resin exporter. China is rich in production capacity of ethylene, and there is relatively abundant raw materials pyrolysis C5. With the improvement and popularization petroleum resin technology, more and more enterprises have the capacity of production and processing of petroleum resin, and the production capacity of petroleum resin is expanded.

Continued but low growth in oil consumption in China, dependence on foreign is 60.6%. Data show that China's oil apparent consumption was estimated at 543 million tones in 2015, it increased 25 million tons compared with the previous year. Domestic ethylene production increases supported petroleum resin market of carbon five and C9, the Mainland of China ethylene production capacity is 15 million tons in 2010, the production is 13.8 million tons, by-product carbon five's output is 180 tons and carbon nine production is 1.4 million tons.
