Granular Urea, also known as coated granular urea or agricultural granular urea, is a high-quality nitrogen fertilizer, renowned for its superior characteristics compared to prilled urea. With a nitrogen content of 46%, it stands out as the most concentrated form of solid nitrogen fertilizer available. This product is designed for optimal performance in various agricultural and horticultural applications.Granular Urea consists of larger particles with an uneven shape, which contributes to its robust physical properties. Unlike prilled urea, it is less prone to breaking and maintains its integrity during handling and application. The product is available in particle sizes ranging from 2 to 4 mm, making it suitable for use with conventional spreading equipment.The main advantage of granular urea is its high nitrogen concentration, which promotes vigorous plant growth. It can be applied directly to the soil or blended with other fertilizers such as phosphate and potash to create a comprehensive NPK (nitrogen, phosphate, and potash) mix. This versatility allows it to meet various plant nutritional needs effectively.Produced by Khorasan and Shiraz Petrochemical Companies, this agricultural granular urea is ideal for early-season grass fertilization and cereal top-dressing later in the season. It ensures precise spreading up to 24 meters, making it a reliable choice for both hand spreading and mechanical spreaders.
Granular urea is a key ingredient in the production of various other fertilizers. Its high nitrogen content makes it an essential component for creating blended or specialized fertilizers, enhancing nutrient delivery for diverse agricultural needs.
Used in the production of melamine through a reaction with formaldehyde. Melamine is a crucial component in melamine-methanal resins, which are used for durable coatings, laminates, and kitchenware, benefiting from urea’s chemical properties.
Granular urea is used in synthesizing urea-formaldehyde resin. This resin is vital in manufacturing adhesives, particleboard, and other wood products, providing strong bonding and durability in industrial applications.
Coated granular urea is employed in the reduction of nitrogen oxides (NOx) emissions from diesel engines. It is used in Selective Catalytic Reduction (SCR) systems, where it reacts with NOx to produce nitrogen and water, thus mitigating air pollution from vehicles.
It is applied to grass early in the growing season to promote healthy, early-season growth or used for top-dressing cereals later in the season. The high nitrogen content supports robust plant growth and improves crop yield, making it a versatile agricultural tool.

PVC S57 is a high-quality, free-flowing vinyl chloride homopolymer resin with a low molecular weight, produced through suspension polymerization. This grade of PVC, with a K value of 56.1-57.8, exhibits low porosity and very high bulk density, making it ideal for rigid applications and high machine throughput. With a viscosity range of 0.665-0.72 and a bulk density between 0.5-0.62, PVC S57 is well-suited for use as an additive polymer in specific applications. Known for its thermoplastic properties, it contains approximately 57% chlorine by weight and is widely used in various forming methods. It is supplied in powder form and is produced by Abadan and Ghadir Petrochemical Company under HS code 39041090. .
PVC S57 is a versatile resin extensively used across various industries due to its excellent properties. In injection molding, it is ideal for producing rigid PVC parts and pipe fittings, where its high bulk density and low porosity are particularly beneficial. For sheet extrusion, PVC S57 is utilized in the manufacturing of rigid films and both compact and foamed rigid sheets.
In calendaring processes, this grade is employed for creating rigid films and sheets. Additionally, it is used in the extrusion of flexible sections and hoses. PVC S57 is commonly applied in electronic and electrical equipment, special packaging, and most notably, in the production of PVC fittings, where its characteristics ensure durability and precision.
