C5 petroleum resin has low production cost and large use. It can be made into block or granular form and used as tackifier in pressure-sensitive adhesives. Hot melt adhesive is an adhesive that is heated and melted to generate fluidity, coated on the object to be bonded, and solidified and bonded after cooling.   EVA has excellent adhesion, softness, heating fluidity and cold resistance, its cohesion is large, the melting surface tension is small, and it has adhesion to almost all substances, chemical resistance, thermal stability, weather resistance and electrical properties. Excellent, widely used in book binding, wood processing, plywood production, packaging, canning, shoemaking, etc. Usually, the hot melt adhesive with EVA as the base material needs to be blended with two or more grades of EVA as the base material. In addition to petroleum resin, inorganic fillers, antioxidants, and pigments can also be added according to user needs, such as: TiO2, carbon black, etc. Petroleum resin has good compatibility with EVA with low VA (vinyl acetate) content, but has poor compatibility with EVA with high VA content.   The preparation process of this hot-melt adhesive is as follows: add EVA, talc, and antioxidant 1010 to the reaction kettle in sequence in a certain proportion, heat to melting, stir vigorously and raise to a certain temperature, then add tackifier petroleum resin, stir for a period of time in the molten state, and then add DOP (dioctyl phthalate) to adjust the viscosity to moderate. At this time, the system is in a uniform and viscous molten state. After cooling, a yellow solid is obtained, which is a hot melt adhesive.

From the perspective of market trends, with the growth and maturity of emerging markets such as new energy vehicles, composite materials, and surface treatment, the per capita consumption of functional silanes in my country is still lower than that of developed countries. In the future, sales of functional silanes will continue to grow. The speed remains stable. It is estimated that by 2023, the total production capacity of functional silane will reach 564,000 tons, the total output will reach 389,000 tons, and the consumption will reach 278,000 tons in the same period.   From the perspective of product trends, after years of development, the variety, quality and output of Functional Organosilane in my country have made great progress. With the rapid development of emerging industries such as solar energy, lithium batteries, LED lamps, and 5G networks, the demand for additives in sealants and adhesives is also increasing. For example, in room temperature vulcanized silicone rubber, the demand for neutral rubber is growing rapidly, the deketoxime type rubber has become the mainstream of the market, and the acid type rubber is shrinking. The future development of neutral rubber will be a general trend. In addition, the development of domestic conventional functional silanes is very rapid, but the development of high-end functional silanes is still significantly different from that of foreign countries. In the future, my country's functional silanes will develop in the direction of high-end, specialization and novelty.   From the perspective of competitive trends, in recent years, the functional silane industry has experienced significant consolidation after explosive growth. Some small enterprises have withdrawn one after another, and production capacity tends to be concentrated in large enterprises. At the same time, under the background of stricter safety and environmental protection requirements and continuous advancement of supply-side reforms, silane enterprises will develop in the direction of scale, integration and regionalization.   In 2022, ECOPOWER plans to produce 7000T/Y of new functional organosilane products.

Precipitated Silica At the beginning of 2022, the price of silica raw materials will continue to rise, and the middle and downstream enterprises cannot bear the pressure. The letter of price increase emerges one after another! Recently, another large downstream listed company said that it is difficult to bear the cost pressure of rising raw materials and will implement price increases from March 1. The company said that in the context of soaring raw material prices and rising logistics costs, the company will adjust product prices in July 2021. However, since the last price adjustment, raw material prices have continued to rise sharply, logistics are tight, and energy costs remain high. In the event of unavoidable cost increases, the company will continue to make every effort to ensure a stable supply of products, such as increased productivity and substantial cost reductions. But in the case that the company's efforts are far beyond the limit, as a last resort, the company will adjust the product price again.
