C9 Petroleum Resin Development Trend

C9 petroleum resin development trend


Foreign: Consumer production is concentrated in the United States and Japan

At present, foreign petroleum resin production technology has become more mature, new varieties have emerged, and the application fields have been continuously expanded. It has developed into a multi-variety, multi-brand, multi-purpose functional synthetic resin. In particular, hydrogenated petroleum resins have developed more rapidly. In particular, the subsequent deep processing has been developed into hydrogenated C9 petroleum resin, hydrogenated C5 petroleum resin, dicyclopentadiene (DCPD) hydrogenation, C5/C9 copolymerization hydrogenation, petroleum resin modification and many other varieties, multi-brand, special-purpose High-grade products; deep processing of oil produced in the synthesis process, has developed into a high-grade solvent oil for the production of hydrogenated narrow fractions. The main products of foreign C9 Resin factory are: conventional C9 petroleum resin which is polymerized from 140~210°C fraction in cracked C9 fraction; aliphatic modified resin which alkylates C9 aromatic resin with C5 fraction; hydrogenated modified C9 petroleum resin Unhydrogenated water white pure monomer aromatic resin; copolymerized petroleum resin, such as C9 fraction and certain C9 concentrate copolymerization products, has higher iodine value than conventional C9 resin, and has good solubility; using AlCl3 as The catalyst is polymerized, and a secondary polymerization resin having a melting point of 10 ° C, 25 ° C, and 30 ° C is used.


Petroleum resin production equipment is mainly concentrated in ExxonMobil, Eastman, Goodyear, Zeon, KoLon, etc., accounting for the total global petroleum resin. 69% of production capacity. The equipment for hydrogenation resin is mainly concentrated in a few companies such as Exxon Mobil in the United States, Eastman in the United States, Arakawa in Japan, Kolon in Korea, and Heyi in Taiwan, accounting for 92.5% of the total production capacity of hydrogenated petroleum resins in the world. Exxon produces dicyclopentadiene (DCPD) hydrogenated petroleum resin, and Tonex of Japan produces C5/C9 hydrogenated petroleum resin.


The United States mainly uses natural gas as a cracking raw material, mainly based on C5 resin, and its production capacity and technology are in the world's leading position, while C9 resin does not dominate. ExxonMobil is the largest manufacturer in the United States, especially C5 resin production accounts for more than 40% of total US production, with a capacity of more than 150,000 tons. The US petroleum resin is available in a wide range of grades to meet the needs of the market.


Japan's Zeon is Asia's largest producer of petroleum resins with a total capacity of 60,000 tons. In 2006, the company expanded its production capacity of petroleum resin to 25,000 tons. Kolon Chemical Co., Ltd. is another oil resin producer in Asia. The company's total production capacity of C5, C9 hydrogenation and dicyclopentadiene petroleum resin is 60,000 tons.


China C9 Hydrocarbon Petroleum Resin Industry Development Shows Two Major Trends


Recently, the demand for C9 Hydrocarbon Petroleum Resin manufacturers (mainly hydrogenated petroleum resin) has shown an increasing trend, and in 2014, the first C9 hydrogenated petroleum resin core technology in China has made a breakthrough. In 2015, the first DCPD hydrogenated petroleum resin in China was also put into production. The overall development trend of China's C9 Resin suppliers industry is mainly reflected in two aspects: First, the production capacity is gradually concentrated to the dominant enterprises. For example, Shandong Qilong has established production facilities in Zibo, Fushun, Shanghai, etc., Zibo Luhua Yujin and Guangdong Xinhua Yue In Wuhan, there are C9 and C5 production facilities, and the situation of scattered, chaotic and poor will gradually improve. Second, the breakthrough of hydrogenated resin technology is gradually catching up with European and American enterprises.


In the past two years, PETROLEUM RESIN suppliers technology has been quite mature. The petroleum resin industry has been seeking breakthroughs in transformation and development. Hydrogenation of C9, C5, C5/C9 or DCPD petroleum resins will become a hot spot for investment in the industry for a period of time to come.


In recent years, China's major producers have seized the mid-to-high-end resin market. The mid-end market is copolymerized with petroleum resin and cold-poly petroleum resin. Zhejiang Henghe is 4# cold-collecting Petroleum Resin C9 manufacturers. In 2015, Zhejiang Henghe 15,000 tons of copolymerization The resin plant started; the high-end market made breakthroughs in the industrialization of hydrogenated C9 petroleum resin. In June 2014, Panjin Heyun Group's 2000-ton C9 petroleum resin catalytic desulfurization/hydrogenation process production plant was put into operation. However, due to poor sales and serious losses, it was rarely driven in 2015 and has been discontinued. In 2015, Hebei Qiming Chemical Technology Co., Ltd. invested in the 10,000-ton C9 hydrogenation unit built by the catalytic hydrogenation decolorization and odor removal technology of Dalian University of Technology. run


Domestic C9 petroleum resin manufacturers mainly use catalytic polymerization (also known as cold polymerization) and thermal polymerization processes. For the C9 fraction of high dicyclopentadiene (DCPD) content, the quality of the resin produced by the continuous pressure hot polymerization process is relatively high. The larger scale C9 petroleum resin manufacturers generally have more than two production lines of hot polymerization and cold polymerization. , to produce a full range of deep and light color petroleum resins.


In 2020, the total gap will exceed 100,000 tons.


C9 petroleum resin is mainly used in adhesives, rubber, paints, inks, etc., accounting for 75% of total consumption; another 25% is used for light oily varnish, resin varnish, advanced heat adhesive, pressure sensitive adhesive, etc. field. It is estimated that by 2020, the total consumption of China's C9 petroleum resin will reach 400,000 tons. Considering that some new C9 resin units will be completed and put into operation, the total demand for C9 resin is more than 100,000 tons.


On the one hand, the C9 petroleum resin industry on the one hand, the raw material quantity is rising rapidly; on the other hand, the price advantage of the hot poly resin is gone, the mid-end resin is developing at a high speed, and gradually entering saturation, while the domestic enterprises in the high-end resin market are basically blank. In the future, the unprofitable low-end resin market will be further squeezed by the mid- to high-end resin market, giving up part of the raw material share. At the same time, small-scale, low-end products will gradually be eliminated by the market, and there will be several large-scale enterprises in the domestic development situation.
