Ferrosilicon is a ferroalloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel chips, quartz (or silica) as raw materials and smelted from an electric furnace. Ferrosilicon is often used as a deoxidizer in steelmaking, and it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in alloy production and chemical industry, commonly used as a reducing agent

It is the only type of Urea that meets the ISO 22241 specification (Uncoated, Aldehyde, heavy metals free) and the only suitable Urea for the production of AdBlue®/AUS32/ARLA32 solutions. For meeting the ISO 22241 the Urea needs to be of highest purity/quality. Automotive grade urea dissolved within deionized water is resulting in an aqueous urea solution, supporting the reduction of mono-nitrogen oxides exhaust emissions by injection into selective catalytic reduction systems of heavy duty engines. This aqueous urea solution is standardized as AUS 32 in ISO 22241 and consequently the technical specifications for automotive grade urea are derived from this standard.

AdBlue liquid solution is made up of 32.5% urea and 67.5% de-ionised water. You may be wondering, where does the urea in AdBlue ic ammonia and carbon dioxide. The urea is then added to the de-ionised water to create AdBlue. This guarantees quality in accordance with very strict specifications contained in ISO 22241. AdBlue is a diesel exhaust fluid used in vehicles with Selective Catalytic Reduction (SCR) technology to reduce harmful gases being released into the atmosphere. AdBlue is a 32,5 % solution of high-purity, synthetically manufactured urea in de-mineralized water. It is a safe-to-use fluid.

Polypropylene is a polymer whose monomer is propylene (an organic hydrocarbon with the chemical formula C3H6). The chemical formula of polypropylene is (C3H6)n. This polymer is also known as polypropene and is often denoted by the abbreviation PP. Generally, polypropylene is produced via a chain-growth polymerization reaction involving propylene. Toughness and flexibility (exhibited to a large extent especially when the polymerization process involves copolymerization with ethylene). Large thermal expansion. Resistant to organic solvents. Resistant to weak oxidizing agents. Soluble in some organic nonpolar solvents like xylene.
Caustic soda is an alkali salt which is also called Lye. It is the common name of sodium hydroxide. This name is given due to the corrosive nature of this salt on animal and plant tissues. It's a highly caustic base and the alkali that decomposes proteins at ordinary ambient temperatures and can severely burn chemical burns. It readily absorbs carbon dioxide and moisture from the air and is highly soluble in water. It creates a series of hydrates NaOH·nH2O. One of the strongest alkalis is a white solid, with no pronounced odor. The size of the flakes can reach 0.5 mm. NaOH easily dissolves in water and absorbs moisture from the air with the release of a large amount of heat. It has a wide range of applications. The chemical formula of sodium hydroxide is NaOH. Caustic soda it is often use in in the manufacturing of petroleum products and manufacturing of pulp and paper.
YETD-MC has a production line of 400,000 tons of synthetic ammonia and 600,000 tons of urea. High-quality raw coal is used as raw material to ensure product quality. The recycling project also provides about 80,000 tons of ammonium sulfate, which in turn is an important raw material for 100,000 tons of compound fertilizer. We can provide ammonium sulfate (N20.5%), urea (N46%), various types of compound fertilizers (N+P+K=57% MAX). Urea, also called carbamide, the diamide of carbonic acid. Its formula is H2NCONH2. Urea has important uses as a fertilizer and feed supplement, as well as a starting material for the manufacture of plastics and drugs. It is a colorless, crystalline substance that melts at 132.7° C (271° F) and decomposes before boiling. Because its nitrogen content is high and is readily converted to ammonia in the soil, urea is one of the most concentrated nitrogenous fertilizers. An inexpensive compound, it is incorporated in mixed fertilizers as well as being applied alone to the soil or sprayed on foliage. With formaldehyde it gives methylene??urea fertilizers, which release nitrogen slowly, continuously, and uniformly, a full year??s supply being applied at one time.
