Ethylene tar has no market price, and coal tar and oyster sauce are exported in large quantities. The three raw material oils used in carbon black production are facing a complete interruption. This is what the reporter learned from the China Rubber Industry Association on September 9. Before this, 18 large-scale carbon black enterprises with an annual output of more than 30,000 tons in China gathered in Tianjin. They negotiated urgently about the supply shortage of carbon black raw materials since July and called for relevant state agencies to intensify macro-control efforts. Carbon black enterprises normally produce.
According to reports, coal tar and oyster sauce can meet production requirements in the past, except for the tightness of ethylene tar. However, since July, the supply of carbon black raw materials in the domestic market has become uncharacteristically high, not only because prices have risen sharply, but also supply is scarce. In some regions, the price of coal tars has doubled, the prices of oyster and ethylene tars have also risen by more than 40%, and there is no market in most regions, making the supply of raw materials for carbon black an emergency.
It is understood that the current large-scale carbon black enterprises in China have all cut production, and small-scale enterprises basically stop production. Even more severe is that, even so, carbon black stocks of raw materials can only be maintained until the end of September, if the October is still not normal production, the inventory of carbon black in all companies plus the tire plant turnover, only enough for tire companies to use 20 Days or so, this will seriously affect the normal production of tire companies, but also bound to affect the normal production of the automotive industry.
According to analysis by industry experts, there are three main reasons for the shortage of carbon black raw material oil: First, due to the increase in the price of heavy oil, ethylene producers use ethylene tar as their own fuel, and external supplies are becoming less and less. According to the carbon black division of the China Rubber Industry Association, the consumption of ethylene tar in the carbon black industry last year accounted for nearly 15% of the carbon black raw material oil and nearly 50% of the ethylene tar oil production, but this year it dropped significantly, especially in the near future. There is no market price. Second, glass and ceramic companies have been rushing to buy coal tar and oyster oil, replacing expensive heavy oil as fuel for production, and even blocking high-priced raw materials for carbon black plant. Shanxi Zhixin Chemical Co., Ltd., Shanxi Juyuan Carbon Black Co., Ltd., Shanxi Hengda Carbon Black Co., Ltd. and other companies are located next to coking companies, but they do not get coal tar. Third, the export volume of coal tar and oysteroil surged and increased by 4 times year-on-year in the first half of this year.
To this end, the China Rubber Industry Association on the 8th to the National Development and Reform Commission urgently called for the cancellation of 13% of coal tar, oyster oil export tax rebate policy, limit or prohibit coal tar, oyster sauce exports, and require the relevant departments to coordinate the import of ethylene tar.
A pigment Thickening Agent, also known as a rheology modifier or thixotropic agent, is a type of chemical substance that helps in controlling the viscosity and flow properties of paints, inks, and other pigment-based products. These agents can increase the viscosity of the mixture without changing its other properties such as color, opacity, or drying time.

These agents can increase the viscosity of the mixture without changing its other properties such as color, opacity, or drying time.
The primary function of a pigment thickening agent is to prevent the sedimentation of pigments over time, ensuring a more consistent product quality. This is particularly important for products where the pigment concentration is high. Here are some common types of pigment thickening agents:
1. Polymeric Thickeners: These are large molecules made from polymers that form networks within the paint, providing stability and viscosity.
2. Organic Thickeners: These include substances like bentonite, carboxymethyl cellulose (CMC), and polyvinyl alcohol (PVA). They are often used because they are compatible with a wide range of pigments and solvents.
3. Inorganic Thickeners: Examples include clays like bentonite and kaolin. They work by absorbing water and swelling, which increases viscosity.
4. Hydroxyethylcellulose (HEC): A type of cellulose derivative that can be used to thicken aqueous systems. It's biodegradable and food-grade.
5. Cellulose Ether Derivatives: Such as hydroxypropyl methylcellulose (HPMC) and methyl cellulose (MC), which are used in both waterborne and solvent-based systems.
6. Polyacrylates: Synthetic polymers that can be used to adjust viscosity and stabilize dispersions.
7. Silicones: These can be used to modify the surface properties of pigments, affecting their dispersibility and the final viscosity of the mixture.
Choosing the right thickening agent depends on several factors including the type of pigment, the solvent system, the desired viscosity, and the environmental impact considerations. It's crucial to test different agents under similar conditions to ensure compatibility and optimal performance.
