Superplasticizers are traditionally known for their water-reducing qualities to improve the flow of concrete.
Consult us for acrylic acid price. Acrylic acid is an important organic synthetic raw material and synthetic resin monomer prepared from propylene obtained by oil refineries. Acrylic acid consists of one vinyl group and one carboxyl group, and is the simplest unsaturated carboxylic acid with chemical properties that are flammable, explosive, highly corrosive and toxic.
In 1843, acrylic acid was first discovered by chemists by means of oxidation, and was subsequently widely used in industrial production.

According to product quality classification, acrylic acid (AA) can be divided into esterified acrylic acid (CAA), polymerized acrylic acid (PAA) and high-purity acrylic acid (GAA). Among them, esterified acrylic acid is mainly used to produce acrylate; polymerized acrylic acid is mainly used to produce polyacrylate products; high-purity acrylic acid is mainly used to produce super absorbent resin (SAP), water treatment agent, etc.
The production technology of acrylic acid has undergone many technological improvements since it was applied to industrial production. At present, the production methods of acrylic acid include acrylonitrile hydrolysis method, cyanoethanol method, β-propiolactone method, high pressure Repe method, propylene oxidation method and so on. Among them, the propylene oxidation method of acrylic acid is the main method that most enterprises choose to produce acrylic acid today.
Acrylic acid is at the core of the industrial chain, and a series of compounds can be derived through chemical processes, thus forming a large series of acrylic acid products. Therefore, the acrylic industry chain can be divided into the upstream with oil, natural gas and propylene as raw materials, the midstream belongs to the acrylic and ester industry, and the downstream mainly includes acrylates, SAP, acrylic rubber, high-performance materials, etc., which are widely used in coatings, adhesives, Three major links in the fields of synthetic rubber, textiles, chemical fibers, and building materials.
Propylene is one of the most important chemical products and the basic raw material of the three major synthetic materials. It is mainly used in the production of polypropylene, propylene oxide, acrylonitrile, acrylic acid and other chemicals. In recent years, the global acrylic acid production capacity has maintained steady growth. From 2010 to 2017, the global propylene supply and demand was in a weak balance, and the compound growth rate of production capacity demand was about 4%. In 2018, the global production capacity growth rate reached 4.5%.
In terms of production capacity distribution, Asia-Pacific, North America, Europe, and the Middle East include the global propylene production capacity. With the transfer of production capacity, from 2010 to 2017, the new global propylene production capacity mainly came from the Asia-Pacific region. In 2017, the Asia-Pacific region has concentrated 52% of the global propylene production capacity.
At present, China’s propylene production is about 28.4 million tons/year, imports are about 3.1 million tons/year, and consumption is about 31.5 million tons/year. Acrylic is expected to maintain steady growth in the future as applications such as downstream coatings, adhesives, and superabsorbent resins (SAP) continue to grow.
From the perspective of global propylene production capacity expansion, my country’s propylene has experienced years of capacity expansion. Since 2012, it has surpassed the United States and become the world’s largest propylene production country (35 million tons), and has continued to maintain a continuous expansion trend since then.
In 2018, my country’s propylene production capacity remained the first, reaching 35.6 million tons per year, exceeding the scale of about 15 million tons in the United States, which ranked second, while South Korea, Saudi Arabia, and India followed closely, but all were less than 10 million tons per year.
We have our own factory to produce, and the acrylic acid price will be relatively low. Our acrylic acid price is very favorable, welcome to contact us.
Superplasticizers are traditionally known for their water-reducing qualities to improve the flow of concrete.
Polycarboxylate superplasticiser (PCE) is an important component of plugging slurries.
The woodworking industry is an ever-growing industry that is constantly in need of materials that can improve the appearance of wood. Polishing wax, commonly known as wood wax, is a popular product in the woodworking industry.
Undoubtedly the most controversial wax on the market today. Paraffin is often criticized for being unsafe, but it remains one of the most well-known candle waxes. It is obtained from a petroleum refinery by-product called slack.
With the continuous advancement of science and technology in our country, the quality of construction projects continues to improve. During the actual construction process, in order to ensure the overall quality of the concrete project, admixtures are usually added to the concrete. High-performance water-reducing admixture is used as an admixture. Water-reducing admixture is added to concrete to reduce water consumption and increase the strength of concrete.
Still wondering where you can get good quality waxes in China and abroad? The journey to find the best industrial and non-industrial waxes ends here. With the growing demand for industrial waxes, the Dongke group is committed to producing the finest quality waxes, which are imported in the form of crude oil from all over the world. These are then formulated accordingly to product requirements or customer specifications.
