توضیح اجمالی:
High-quality phosphate fertilizers for agricultural productivity, reliably sourced and globally shipped.
Phosphorus (P) is one of the three macronutrients essential for plant growth. It drives root development, energy transfer (ATP), flowering and grain filling. For commercial agriculture, the most widely used phosphate fertilizers are Diammonium Phosphate (DAP), Monoammonium Phosphate (MAP) and Triple Superphosphate (TSP). Each product has distinct chemistry, nutrient concentration and agronomic advantages — understanding these differences helps agronomists and buyers match fertilizer choice to crop needs, soil chemistry and logistics.
1 – Diammonium Phosphate (DAP)
What DAP is
Diammonium phosphate (DAP) is an inorganic phosphate fertilizer produced by the reaction of phosphoric acid with ammonia. Typical commercial DAP contains about 18% nitrogen (N) and 46% phosphate expressed as P₂O₅ (i.e., roughly 46% P₂O₅). DAP appears as white, hard prills or granules and is widely used as a starter fertilizer and in bulk blended NPKs.
How DAP is made (brief)
Industrial DAP production begins with phosphate rock converted to phosphoric acid (wet-process). Controlled neutralization of the acid with ammonia yields DAP crystal or granule; the product is dried and screened for particle size, density and free-moisture specification. Modern plants control cooling and granulation to ensure uniform prill density and low caking.
Agronomic profile & uses
Handling & logistics
DAP prills are hygroscopic and can cake if exposed to moisture; store in dry, ventilated warehouses on pallets and use moisture-resistant packaging for long export voyages. Standard maritime packing is 50 kg PP/PE woven bags (with liners) or 500–1,000 kg big-bags; bulk shipments by hopper vessels are common for large contracts.
2 – Monoammonium Phosphate (MAP)
What MAP is
Monoammonium phosphate (MAP) is produced by reacting phosphoric acid with ammonia at a different stoichiometry than DAP. MAP usually contains around 11% nitrogen (N) and 48% P₂O₅ (or sometimes expressed as 11-48-0). MAP crystals are highly water-soluble and the fertilizer is commonly used in fertigation, foliar applications and high-value blends.
How MAP is made (brief)
MAP production uses concentrated phosphoric acid neutralized with ammonia under controlled temperature to form a crystalline MAP product. For soluble MAP (for fertigation), manufacturers control crystal size and dryness and often prill or granulate for uniform spreading.
Agronomic profile & uses
Handling & logistics
MAP is slightly hygroscopic; store dry. It is sold as prills or granules (25–50 kg bags), big-bags or as part of NPK blends. For fluid systems, MAP can be supplied in solution form or dissolved on site as UAN/MAP blends.
3 – Triple Superphosphate (TSP)
What TSP is
Triple superphosphate (TSP) is a concentrated phosphorus fertilizer produced by reacting finely ground phosphate rock with concentrated phosphoric or sulfuric acid under controlled conditions. TSP does not contain nitrogen — its distinguishing feature is a very high phosphate concentration: typically 44–48% P₂O₅, with most of the P present as water-soluble orthophosphate — making it one of the most concentrated solid P fertilizers available.
How TSP is made (brief)
The classic TSP route treats phosphate rock with phosphoric acid to produce a dense superphosphate granule. Particle engineering, drying and granulation control solubility and reduce dust. Because TSP doesn’t contain N, it is often blended with urea or ammonium sources to create balanced NPKs.
Agronomic profile & uses
Handling & logistics
TSP is hygroscopic to varying degrees depending on granule quality and manufacturing. Packaging, anti-caking agents and dry storage are important for shelf life. TSP is shipped in 25–50 kg bags, big-bags or sometimes in bulk. citeturn0search9
Market context & supply dynamics
The phosphate fertilizer market (collectively DAP, MAP, TSP and other P fertilizers) is a large, global market driven by food demand, cropping patterns and phosphate rock supply. Recent industry reports estimate global phosphate fertilizer market values in the multi-tens of billions USD and project modest growth driven by population, dietary shifts and fertilizer use efficiency improvements. Major producing countries and companies (phosphate rock and downstream processing) — such as Morocco (OCP), China, India, Russia, Mosaic, Yara and regional producers — dominate global flows and export balances. Because phosphate fertilizer economics depend on phosphate rock, acid availability and energy cost, price and capacity trends can vary regionally and year to year.

Its unique combination of adhesion, waterproofing ability, and durability makes it indispensable in road construction, pavement surfacing, and industrial applications.
Globally, more than 85% of bitumen consumption is allocated to road and highway construction, while the rest is used in roofing, waterproofing membranes, and industrial products.
Plasticizers are vital chemical additives used to increase the flexibility, workability, and durability of polymer materials—most notably polyvinyl chloride (PVC). By embedding themselves between polymer chains, plasticizers reduce intermolecular forces, making materials softer, more elastic, and easier to process.
They play a crucial role across multiple industries, from construction and automotive to medical devices, packaging, and consumer goods.
Among the wide range of available plasticizers, three products dominate the global market due to their excellent balance of performance, cost-efficiency, and safety standards:
DOP (Dioctyl Phthalate), DINP (Diisononyl Phthalate), and DOTP (Dioctyl Terephthalate).
Pigments and dyes are the essential coloring agents used across various industries — from plastics, coatings, and textiles to inks, cosmetics, and automotive manufacturing. They represent a vital segment of specialty chemicals, offering not only vibrant color performance but also durability, stability, and compatibility with modern formulations.
Surfactants, or surface-active agents, are a key class of specialty chemicals that reduce surface and interfacial tension between liquids, solids, and gases.

Butadiene derivatives are high-value chemical families made from the light olefin 1,3-butadiene (C₄H₆). Because butadiene is the principal monomer for a range of synthetic rubbers and elastomers, its derivatives underpin major industrial applications — most importantly the tire and automotive industries, industrial goods, adhesives and specialty polymers. This page explains production, properties, commercial grades and practical procurement advice for synthetic rubbers made from butadiene: Styrene-Butadiene Rubber (SBR), Polybutadiene Rubber (BR) and Nitrile Butadiene Rubber (NBR).
Ethylene derivatives are the industrial compounds produced from ethylene (C₂H₄) that form the backbone of modern plastics, fibers, coatings and many specialty chemicals. Common derivative families include ethylene oxide → glycols (MEG, DEG, TEG), ethylene dichloride (EDC) → vinyl chloride (VCM) → PVC, and vinyl acetate monomer (VAM) for adhesives and paints. Demand for these derivatives is closely linked to global petrochemical feedstock flows (steam-cracker and PDH runs), end-use growth (packaging, textiles, construction, automotive) and regional capacity additions.
Propylene derivatives represent one of the most vital families of petrochemical intermediates derived from propylene (C₃H₆) — a key building block in the global chemical industry. Propylene is primarily obtained from steam cracking of hydrocarbons or as a byproduct of fluid catalytic cracking (FCC) in refineries. Its derivatives play a crucial role in producing a wide array of consumer goods, plastics, fibers, coatings, and industrial materials.
Cyclohexane (CAS 110-82-7) is a colorless, non-polar cycloalkane (C₆H₁₂) widely produced and traded as a petrochemical intermediate. It is principally manufactured by hydrogenation of benzene and serves as a primary feedstock to produce cyclohexanol / cyclohexanone (KA oil), which in turn are converted to adipic acid and caprolactam — the essential intermediates for nylon-6,6 and nylon-6 polymers. Because of its role in the nylon value chain, cyclohexane demand closely follows global polymer, textile and automotive markets.
Phenol (CAS 108-95-2) is one of the most important aromatic intermediates in the chemical industry. Although it appears simple chemically, phenol occupies a central place in global petrochemical value chains — primarily as the feedstock to make bisphenol A (BPA), phenolic resins, and, via hydrogenation routes, intermediates for nylon and other engineering plastics. This page summarizes the substance properties, industrial production routes, commercial grades, primary applications, market dynamics, logistics and buyer guidance — all written specifically for an industrial trading & export audience.
Cumene (IUPAC: isopropylbenzene, CAS 98-82-8) is a colourless, aromatic hydrocarbon that plays a central role in the petrochemical value chain. Nearly all industrial-scale cumene is used as a feedstock to make cumene hydroperoxide, the intermediate for phenol and acetone production — two high-volume chemicals used to manufacture plastics, resins and fibers.
What is Styrene Monomer?
Styrene monomer (CAS 100-42-5)—also called phenylethene or vinylbenzene—is a clear, colorless to pale yellow liquid with a sweet aromatic odor. It is a reactive aromatic hydrocarbon and an essential petrochemical building block used primarily as the monomer feedstock for styrenic polymers (polystyrene, ABS, SAN and many copolymers). Styrene is shipped commercially in stabilized form (with inhibitors added) to prevent premature polymerization during transport and storage.
Benzene (CAS No. 71-43-2) is the archetypal aromatic hydrocarbon: a colorless, volatile liquid with the molecular formula C₆H₆ and a characteristic sweet odor. It is a fundamental petrochemical feedstock rather than an end-use consumer product. Industrial benzene is used almost exclusively as a raw material in the manufacture of derivatives such as ethylbenzene (→ styrene), cumene (→ phenol & acetone), cyclohexane (→ nylon intermediates) and many other high-value intermediates.
