Chinese Gum Rosin based products are used for the manufacturing of paper, paint, soap and printing ink. Since rosin is easily softened and oxidized, in the oil paint industry, the carboxylation reaction of resin acid is usually employed to produce resinate for further use. While in the producing of synthetic rubber and printing ink, resin acid is changed into disproportionate rosin, polymerized rosin, hydrogenated rosin, etc for further use by its double bond reaction.

Raw material for making soap, paper, oil paint, rubber and synthetic resins.
Gum Rosin is also used as an Intermediate for synthetic organic chemicals.

Photovoltaic industry "storage" domestic demand market
After the industry downturn since the second half of last year, many PV companies have finally heard some reassuring news. First, on February 1, the Ministry of Finance issued the "Notice on Doing a Good Job in the 2012 Golden Sun Demonstration". The market is expected to exceed the 600 MW level last year. The research organization Wind Information released data shows that the 2011 annual results announcement has been announced. Only 15 of the 48 solar power sector listed companies experienced pre-reduction, far below market expectations. For the photovoltaic industry that has long relied on foreign markets and has been expanding its capacity, buying equipment, and processing and re-exporting roads, has the crisis been over? Or will the process of industrial integration, transformation and upgrading continue? The rapid decline of the photovoltaic industry is over-reliance on foreign markets and excessive investment in the short-term, laying a huge hidden danger for the rapid decline of the photovoltaic industry. In the past 10 years, China's photovoltaic industry has been arrogant, and by 2007, it has become the world's first photovoltaic cell and component production. country. However, more than 90% of the products are exported, which has laid a huge hidden danger for the rapid fall of China's photovoltaic industry. As the impact of the European debt crisis deepens, European countries have to tighten fiscal spending, cut PV subsidies, and the PV market is shrinking rapidly. In February 2011, Germany passed the PV on-grid price reduction plan, stipulating that only when the installed capacity is less than 3.5GW (1GW=1 billion watts), the PV on-grid price will not be lowered. Otherwise, for every 1GW increase in installed capacity, the PV subsidy reduction will increase. 3%. In May 2011, the new solar photovoltaic subsidy bill approved by Italy limits the annual subsidy to between 6 billion and 7 billion euros, and links subsidies to installed capacity. Since the installed capacity of photovoltaics in the European market accounts for more than 70% of the world's total, the sudden braking of this important engine has brought huge impact on China's photovoltaic industry. In the second largest market, Japan’s demand for photovoltaic products slowed down due to the earthquake. At the same time, the United States, India and other countries have launched a "double-reverse" investigation to Chinese PV companies. The photovoltaic industry, which has been sung all the way, faces a serious oversupply situation. From the domestic situation, due to the profitability of social capital and the partial industry's disregard of actual industry guidance, China's photovoltaic industry has over-invested in the short-term and has a serious overcapacity. In 2008, there were less than 100 PV companies in China, and now there are more than 500. The overall production capacity has reached 30GW to 40GW, while in 2011, the global PV installed capacity was only 21GW. Inward digging is imminent. Since the end of last year, China has successively issued a series of policy measures to continuously expand the optoelectronic demand in the domestic market. In order to increase the domestic market demand for solar power generation from the policy, China has incorporated solar power into energy development plans for the first time this year. The specific goal of 3GW. The market is expected to eventually exceed the final size. Meng Xianyu, vice chairman of the China Renewable Energy Society, said that domestic PV companies cannot always rely on the international market and must pay more attention to the domestic market. In the past, China generally built large-scale photovoltaic power plants in the western region, and carried out long-distance transportation to the eastern load center through large power grids. Meng Xianyu said that during the "Twelfth Five-Year Plan" period, China's photovoltaic power generation will pay more attention to the development of distributed photovoltaic power plants. This type of distributed photovoltaic power station has good economics and less interference to large power grids. 90% of foreign photovoltaic power generation is distributed energy. From the current operation, it is also relatively stable. The Swiss Sarasin Bank recently released a survey report that is also optimistic about the solar demand in the Chinese domestic market. The report pointed out that between 2011 and 2015, the European solar market will shrink by 5% per year, but due to the development of emerging photovoltaic markets such as China, the global PV market demand this year. It will still increase by 20%. From 2010 to 2015, the global PV market will grow at an annual rate of 18%. From a policy perspective, since the end of 2011, China has successively issued a series of policy measures to continuously expand the demand for optoelectronics in the domestic market, prompting PV companies to pay more attention to the domestic market. It is worth mentioning that the financial industry also supports the development of photovoltaic leading enterprises through various means such as credit. In November last year, the China Development Bank provided a 30 billion yuan strategic credit to Hanergy Holding Group. The first two breakthroughs are self-built photovoltaic power plants, and the second is solar energy building integration. Industry insiders said that the photovoltaic industry should start the domestic demand market, and should focus on breakthroughs in two aspects. The first is self-built photovoltaic power station. According to research reports, from the perspective of the PV industry chain, the power station is still the highest return on investment in the PV industry chain. Under the policy support, the downstream power station can become a source of stable future cash flow for PV companies. At present, a number of photovoltaic companies such as Hanergy Group have expanded to the power generation terminal, forming a whole industrial chain of equipment manufacturing research and development, battery production and solar power generation. The second is the integration of solar energy buildings. The integration of solar energy buildings has the characteristics of not occupying additional land resources, reducing electricity transmission and transmission losses in situ. At the same time, the peak of photovoltaic system power generation and the peak of building electricity consumption basically overlap, which can alleviate power shortage, which is a good direction in the development of distributed energy. In 2011, Hanergy Group successively put into operation bases such as Sichuan Shuangliu, Guangdong Heyuan and Zhejiang Changxing, and will form 2GW capacity this year. At the same time, the cost of photovoltaic power generation has also been declining. Experts said that due to the development of photovoltaic technology, it is expected to achieve parity online. Charles Gay, president of Applied Solar, believes that due to China's advantages in supporting facilities such as smart grids, China will achieve grid parity around 2018. Compared with the domestic PV industry's nearly 40 GW capacity, the domestic 3GW development target is still relatively small this year. Meng Xianyu said that the domestic solar industry will undergo a difficult adjustment period in the short term, but the prospects for the PV market are still good in the long run.
