Precipitated Silica results in the structuring of the silicone rubber, mainly based on a large number of hydrogen bonds between Precipitated Silica and high molecular weight polysiloxanes.   Reinforcing fillers for silicone rubber can be divided into reinforcing fillers and non-reinforcing fillers according to the reinforcing effect. The former has a diameter of 10~50nm and a specific surface area of ​​70~400m2/g. The effect is better; the latter is usually 300~10000nm, the specific surface area is below 30m2/g, and the reinforcement effect is poor. The reinforcing filler used in silicone rubber mainly refers to synthetic Precipitated Silica, also known as Precipitated Silica. Precipitated Silica is divided into fumed Precipitated Silica and precipitated Silica.   Fumed Precipitated Silica The size, specific surface area, surface properties and structure of fumed Precipitated Silica particles are related to the ratio of raw gas, combustion rate and residence time of SiO2 core in the combustion chamber. The finer the fumed Precipitated Silica particles, the larger the specific surface area and the better the reinforcement effect, but the worse the performance. On the contrary, the particles are coarser, the specific surface area is smaller, and the enhancement effect is poor, but the operability is better. Fumed Precipitated Silica is one of the most commonly used silicone rubber reinforcing agents. The rubber compound reinforced with it has high mechanical strength and good electrical properties after vulcanization. Fumed Precipitated Silica can be used in combination with other reinforcing agents or weak reinforcing agents to prepare rubber compounds with different application requirements.   SAI800 High Anti Yellowing Silica in Silicone Rubber » Medium particle size: 10-14um and BET specific surface area 130-160 m²/g   SAI779-1 Reinforcing filler Silicone Rubber » Medium particle size: 10-14um and BET specific surface area 150-180 m²/g   SAI779 Good Processing Precipitated Silica in Silicone Rubber » Medium particle size: 10-14um and BET specific surface area 1120-160 m²/g    

In the first quarter of this year, the net profit of listed companies in the silicone field generally achieved positive growth. "The price of silica gel will continue to rise this year, mainly driven by factors such as the boost in global chemical product market demand after the impact of the new crown pneumonia epidemic, the recovery of industry demand, and the domestic 'dual control' policy. It will cause supply to closely follow demand, so the increase will not be too large." Hong Qianjin, a researcher at the Academia Sinica, said in an interview with a reporter from China Business News that the current large-scale expansion of the company's silica gel project will not cause excess production capacity. Due to the low per capita GDP of emerging market countries, there is still a large gap and growth prospects in per capita organic silicon consumption compared with developed countries. Therefore, emerging market countries have a large market demand space, which is conducive to balancing the gap between my country's organic silicon export and production capacity. Over the past two years, the focus of global manufacturing has shifted to China. Due to the strong export of terminal downstream products, new application scenarios in the market continue to expand, and demand continues to grow; in addition, silica gel is still concentrated in large and medium-sized production enterprises. At the same time, from the perspective of the international market, the imbalance between supply and demand in the global shipping market has rapidly changed from oversupply to undersupply. The import dependence of European, American and Southeast Asian countries on Chinese silicone products continues to increase. Domestic enterprises export well, prices rise, and overseas sales are more successful. The growth rate of the industry has increased significantly.

Silane coupling agent has played a great role in coatings, rubber and other industries, especially its excellent adhesion, which has played a significant role in product production and processing. We know that silane coupling agents are mainly used to improve the adhesion of inorganic base materials, such as metal, glass products, etc., but have little effect on organic base materials. The self-polycondensation in the silane part of the silane coupling agent can form a spatial network structure independently, thereby increasing the crosslinking density of the coating and the chemical resistance of the coating. At the same time, the other end of the silane reacts with the resin system and can be cross-linked with the resin, so the silane can act as a bridge between the resin and the substrate, thereby increasing the adhesion. In addition, the silane in the silane coupling agent has another effect, that is, it can be used to treat the pigment and filler to reduce the viscosity of the system.

Functional silanes are widely used in rubber processing, adhesives, composite materials, metal surface treatment and building waterproofing. A class of functional silanes, mainly used in the rubber industry; it can effectively improve the binding ability of silica fillers and rubber molecules, and can promote rubber vulcanization. At the same time, it has the functions of coupling agent and accelerator vulcanizing agent, and has become the most widely used in radial tire production. important raw material. According to Markets and Markets data, the global functional silane market will increase from US$1.33 billion in 2015 to US$1.7 billion in 2020, with a CAGR of 5% from 2015 to 2020; among which, the strong demand for silane in the Asia-Pacific region is driving the global silane market. main factor for growth. According to SAGSI statistics, in 2019, my country's functional silane production capacity is about 430,000 tons/year, and its output is about 279,000 tons. It is already the world's largest producer of functional silanes. SAGSI estimates that by 2023, my country's total output of functional silanes will increase. It will reach nearly 390,000 tons, and the global output will further increase to 72.3%; in 2019, the domestic sulfur-containing silane output will be 89,700 tons, accounting for 32.2% of the output, which is the largest variety of functional silane production in my country. Considering the gradual implementation of domestic green tire regulations and the gradual maturity of the new energy vehicle market, we estimate that the annual domestic output of sulfur-containing silane is expected to reach 125,600 tons in 2023. In addition, with the steady development of rail transit, composite materials and carbon fiber, and building waterproofing industries, the demand space for functional silane industry will be broader in the future.

After the Spring Festival, there was short-term replenishment downstream, and the market demand had a short-term improvement. In addition, the rise in raw materials supported the overall increase in the price of C5 petroleum resin. However, the downstream infrastructure was not fully implemented in February. Rising and market demand is sluggish, and manufacturers are under great inventory pressure. Based on the above analysis, the domestic C5 petroleum resin cost and supply are not as good as the demand, and the market continues to be weak. According to customs data, from January to February 2022, the export volume of petroleum resin with domestic tariff number 39111000 was 56116.7 tons, compared with 2021. From January to February, there was a slight increase of 56,270 tons, but in view of the continuous decline in domestic production in March, it is expected that the export volume of petroleum resin may continue to decline slightly in March. In the second quarter of 2022, the price of cracked C5 will enter a downward channel, the cost support of C5 petroleum resin will weaken, and the inventory of domestic manufacturers is high, and the consumption of market resources will still take time. At present, the market demand has not improved, and the market still needs to wait and see the changes in the epidemic situation. Therefore, the C5 petroleum resin may maintain a weak market in late April, and the market may usher in a turnaround in May.

In recent years, with the continuous optimization of related production technologies, my country's C5 petroleum resin production capacity and output have achieved growth. At this stage, my country's C5 petroleum resin production capacity has reached 550,000 tons/year. The activity and selectivity of hydrogenation catalysts determine the performance of C5 petroleum resin products. With the expansion of downstream application fields of C5 petroleum resins, the market demand for C5 petroleum resins is gradually increasing. Under this background, high-quality, high-performance hydrogenation catalysts demand Release, high-end C5 petroleum resin hydrogenation catalyst has become the key direction of industry research.   Historically, domestic petroleum resins are mostly non-hydrogenated resins. However, with the improvement of domestic raw material quality, process improvement and continuous maturity of technology, there are many sets of hydrogenated resin units planned to be put into operation in the future, which will make resin products or leap into one. new level. The development of the world economy and the accelerated pace of infrastructure construction in emerging economies will further increase the demand for petroleum resins.
