Evaluation.

1 Raw material production and market overview

The amount of phenol needed for global phenolic resins is 3.255 million tons in 2011 and 3.386 million tons in 2012 (an increase of 2.9% in 2012 compared to 2011). The total global phenol demand was 8.771 million tons in 2011, and was 92.46 million tons in 2012 (an increase of 0.3% in 2011 compared to 2011). The phenol used in phenolic resins accounted for 36.62% of the total.

In 2011, the global phenol plant production capacity was 100.98 million tons: of which US companies such as Sunoco, Shell, and Innos Phenol totaled 2,747,000 tons; Inos Phenol, Polimeri and other companies in Western Europe totaled 2.53 million tons; Japan’s Mitsui Chemicals, Mitsubishi Chemical and other companies totaled This was 870,000 tons; Asia (excluding Japan), MPS (Singapore), FCFC (Taiwan), Kumho P&B (Korea), China, etc., totaled 3.2 million tons; original Eastern Europe, Central and South America, South Africa, etc. totaled 652,000 tons. The amount of phenol used in Asia (including Japan) for phenolic resins was 1.529 million tons in 2011 and 1.622 million tons in 2012 (an increase of 5.7% in 2012 compared to 2011). The total amount of phenol used in phenolic resins in 2012 was 34%. [1]

The Global Phenolic Resin Association (GPRA) meets twice a year and in May 2013 in Singapore. Momentive (the world's largest phenolic resin company), United States SI (Schenectady International), Japan's Sumitomo, Korea Kolon, Slovenia Fenolit, Russia UCP, China Phenolic Resin and Plastics Industry Association And so made a comprehensive technical exchange. The main contents are: "Safety Maintenance of Phenolic Resin Production Facilities - Operating Permit", "Phenolic Resin Dust Risk Management", "Global Harmonized System for Classification and Labeling of Chemicals", and exchange of global phenolic resin developments, updated Formaldehyde environmental protection requirements and policies. GPRA complies with relevant international laws, in particular the anti-monopoly law, and it is impossible to exchange prices and other issues. However, exchanges on safety, environmental protection and human health are beneficial to the healthy development of the global phenol industry.

According to reports, Hexion and Momentive have merged into the world's largest specialty chemical company and thermosetting resin producer. The combined company uses the name of Momentive Performance materials.

Momentive Union has established its first manufacturing plant in Zhenjiang, Jiangsu, China, which is adjacent to the original production facility of Zhenjiang Taiwan Liancheng Chemical Industry Co., Ltd. The new plant will produce a full range of specialty thermoplastic phenolic resins and A-stage thermosetting phenolic resins, which will be sold under the industry-leading trade names such as BakeliteTM resins and Durite resinsTM. These materials are used in applications such as refractory materials, friction materials, abrasive materials and electronic equipment. One of Momentive's predecessor companies invented phenolic resin. Momentive has more than 100 years of history in phenolic resin technology innovation and product improvement. The project was put into trial operation in July 2013 and the first phase will produce 80,000 tons of phenolic resin annually. [2]

In May 2013, the project of the US Laiokete Chemical (Nanjing) Co., Ltd. was completed in Nanjing Chemical Industry Park. The company solely invested in the chemical park to invest 42 million US dollars to build an annual output of 36,000 tons of resin adhesives and 15,000 tons of formaldehyde a project. It mainly produces alkyl phenolic resin adhesives and thermoplastic phenolic resin adhesives. The greatest feature of these products is high temperature resistance, adhesives used in automotive tires, abrasives in automotive engines, brake pads, and more. In addition, insulation building materials are also being developed. China's automotive industry is growing rapidly, demand for resin products is very high, and the phenolic resin market is increasing at a rate of 12% per year. The second phase of 70,000 tons will also be put into operation around 2015. According to reports, Michelin, Bridgestone, Goodyear and other well-known tire brands are customers of St. Lekote. The important reason for placing the project in Nanjing Chemical Industry Park is that the enterprises in the district can provide raw materials for the company and form the industrial chain. The isobutene in the Yangzi Petrochemical BASF II expansion project is one of the raw materials of the product, and the district Ineos is able to supply phenol, plus 15,000 tons of formaldehyde produced by the company each year. Wastewater treatment will go through three steps. First, the waste water will be purified and filtered. 95% of the formaldehyde and phenol in the waste water will be recycled. In the second step, the molecular chain of the low-density waste water will be broken through physical methods. In the final step, the waste water will be sent to special In the biological bacterial group, the treated wastewater was decomposed and the COD concentration reached 250 mg/L. The company produces no more than 20 tons of wastewater per 100 tons of product, while the wastewater treatment plant can process 40 tons of wastewater per day. In addition, the company will also construct waste gas incinerators to carry out over-oxidation of the exhaust gas. It is understood that the concentration of free formaldehyde that is not involved in the reaction during the entire production process is about 0.5%. [3]

The Finnish Tyre Chemical Company announced on October 12, 2012 that on the basis of debt-free cash, it sold its Asia division, Finland Tyre Asia Pacific, to Japan's Aiwa Industrial Co., Ltd. for a price of 150 million euros ($194.7 million). According to Tyre of Finland, the sale of Asian operations is in line with the company's strategy and will focus on the European market, especially the phenolic resin business. The Tyre Group's Asia-Pacific business has a history of more than 40 years, and it has 18 factories and 1,200 employees in 8 countries with annual net sales of 220 million Euros. This service is largely an independent operation serving many terminal markets. Relevant person in charge of Japan's Aiwa Industrial Co., Ltd. said that the acquisition of Finland Tyre Asia-Pacific Company has greatly benefited the company. This acquisition is a major strategy for Aihua Industrial to develop overseas markets. [4]

2 Technological Developments

Japanese phenolic molding plastics are mainly researched and developed with high mechanical strength, high heat resistance and good tracking resistance. According to the statistics of 2011, the production and sales of mold plastics in Japan were 27,600 tons, of which 1918 tons (6.9%) were in electronic machinery parts, 3582 tons (13%) in heavy electrical machinery parts, and 4052 tons (14.7 tons) in electrical machinery parts. %), 12,288 tons of vehicle parts (45.5%), kitchen appliances, groceries, 1067 tons (3.87%) and exports 4,653 tons (16.8%). [7]

The miniaturization of electronic equipment is accompanied by the increase in the density of circuit components. Attention must be paid to the issue of heat release. Sumitomo Corporation of Japan has developed insulated heat-dissipating phenolic molding compound, including PM-TX115, specific gravity 2.44, thermal conductivity 1.5w/mk, bending strength 115Mpa, bending elastic modulus 19000Mpa, insulation resistance 1×1012Ω (normal), 1×1011Ω (after boiling). Others include PM-TX130 and PM-9820.

Sumitomo Corporation also modified phenolic resins, selected inorganic fibers as filling materials, and modified the surface state of molding compounds. PM-8280 (CTI 175V) and PM-9250 (CTI 250V) have been successfully developed. Sold to the Chinese market. Japan also vigorously develops glass long fiber reinforced phenolic molding compounds, grade GF9201L12 long glass fiber reinforced varieties, its specific gravity is 1.78, linear expansion coefficient: parallel 10ppm, straight 22ppm, tensile strength 215Mpa, tensile modulus 28Gpa, bending Strength 380Mpa, bending elastic modulus 23Gpa, compressive strength 440Mpa, pendulum impact strength 100KJ/m2, specific tensile strength 121Mpa, specific tensile modulus 16Gpa, specific compressive strength 216Mpa, carbon long fiber reinforced Phenolic molding compound CF9010L12 has better performance.

Foreign scientists through the study of phenolic resin and its products, found that they have a prominent flame retardant when the fire, almost no smoke and toxic gases, which is the internationally recognized so-called FST (Fireproof, Smokeless, Toxicityfree) characteristics. The phenolic foam (PF) produced has a very light density (27-35kg/m3) and has excellent energy-saving insulation and sound insulation. Phenolic foam (PF) has a low thermal conductivity and is approximately twice as energy-efficient as conventional insulation materials such as rock wool, glass wool and expanded perlite. It is recognized that its energy-saving insulation performance ranks first in all insulation materials, and some people call it "the king of insulation" or "the third generation of insulation materials."

In industrialized countries such as the United States and Japan, there are strict fire prevention requirements for wall insulation for important buildings and high-rise buildings. In recent years, the relevant construction departments in various countries have turned their attention to PF, which is both energy-saving and fire-proof, and used in wall insulation systems. British Promaloc Products Co., Ltd. is a well-known manufacturer of phenolic exterior insulation boards. Its phenolic foam (PF) fireproof performance meets British Standard BS476-7. After years of development and research, the company developed and implemented a set of complete and mature specifications for construction application technology systems in accordance with British standards. In the 1990s, it was successfully applied to masonry or concrete walls and whether it was new or Existing, high-rise or low-rise buildings can be applied. The company declared that the external insulation system will not be damaged for at least 30 years after the construction of the public building or residential house. Another example is Asahi Kasei Building Materials Co., Ltd. has conducted in-depth research and development of phenolic foam (PF) insulation materials for many years. In recent years, the company launched a PF insulation board under the trade name Neoma, which has passed fire protection tests in Japan, China and the United Kingdom.
