Urea

Urea is a high-quality nitrogen fertilizer, featuring a minimum nitrogen content of 46%. It appears as white crystalline prills or granules with high solubility and stable efficiency. As the most widely used nitrogen source, it promotes plant growth and improves crop yields. It is also applied in industrial manufacturing, feed additives, and chemical production. Our urea complies with international agricultural and industrial standards, certified by ISO 9001 and ISO 14001. It is packed in 25kg, 50kg bags or 1000kg jumbo bags for safe transport. With stable quality, high efficiency, and competitive pricing, our urea is widely trusted by global customers in agriculture and industry.

Zinc sulphate

Zinc Sulphate is an important zinc-containing inorganic compound, available in monohydrate and heptahydrate types. It appears as white crystalline powder or granular with a minimum purity of 98%. It features good solubility, stable performance and high zinc content. It is widely used in agriculture as fertilizer, in feed as mineral additive, and in industry for electrolytes, water treatment and dyes. Our product meets industrial, agricultural, feed and food grades, certified with ISO 9001, ISO 14001, REACH and FDA standards. It is packed in 25kg PP/PE bags or 1000kg jumbo bags. With reliable quality, stable supply and competitive prices, our Zinc Sulphate is highly popular in global markets.

Potassium Nitrate

Chemical raw materials: Used to manufacture black gunpowder, mining gunpowder, ignition wires, firecrackers, etc., and are also used in fireworks to produce purple sparks. Mechanical heat treatment: A salt bath used for quenching can achieve good performance of metal parts during the quenching process. Ceramic industry: used for manufacturing porcelain glaze pigments, which can give ceramic products rich colors and good glossiness. Glass industry: used as a glass clarifying agent, it can remove bubbles in glass, improve the transparency and quality of glass, and can also be used to manufacture automotive lamp glass shells, optical glass cathode ray tube glass shells, etc..

Calcium Ammonium Nitrate

Calcium ammonium nitrate (Ca (NO3) ₂ · NH ₄ NO3, commonly used as fertilizer) relies on the advantages of "nitrogen calcium co supplementation", good water solubility, fast fertilizer efficiency, and no acidification of soil. Its core application is in the agricultural field, and it also covers a small amount of industrial industries. High efficiency compound fertilizer: containing 15%~18% nitrogen (mainly nitrate nitrogen, with a small amount of ammonium nitrogen) and 10%~12% calcium, balancing crop nitrogen requirements and calcium nutrition supplementation, avoiding calcium deficiency caused by single nitrogen supplementation.

Potassium Dihydrogen Phosphate(MKP KH₂PO₄)

Potassium dihydrogen phosphate (KH ₂ PO ₄) relies on high-purity phosphorus and potassium nutrients (containing about 52% P ₂ O ₅ and about 34% K ₂ O), excellent water solubility, and chemical stability. Its core application is in agriculture, and it also covers industrial, pharmaceutical, and other fields. It is an efficient phosphorus and potassium fertilizer: as a "phosphorus potassium binary compound fertilizer", it does not contain chlorine and has low salt content, which can quickly supplement the phosphorus and potassium needed by crops. Phosphorus promotes flower bud differentiation and fruit development, while potassium enhances lodging resistance, disease and pest resistance.

Magnesium sulfate

Magnesium sulfate (MgSO ₄) and its hydrates (such as magnesium sulfate heptahydrate MgSO ₄ · 7H ₂ O) rely on the nutritional properties, physicochemical stability, and medicinal effects of magnesium elements, and are widely used in multiple industries such as agriculture, medicine, and chemical industry. Fertilizer raw materials: as the core component of "magnesium sulfur binary fertilizer", they supplement the magnesium and sulfur elements needed by crops. Applicable crops: Especially suitable for fruits, vegetables, flowers, and field crops (such as rice and corn), it can prevent yellowing of leaves and poor growth caused by magnesium deficiency in crops, and improve yield and quality.

Potassium Carbonate

Potassium carbonate (K₂CO₃, also known as potassium alkali) is widely used in various industries such as chemical, food, and agriculture due to its alkalinity, stability, and nutritional properties. In the chemical industry, it is used as a basic chemical raw material, glass manufacturing, dye and pigment, and as a filler and reinforcing agent for rubber products; Food industry: food additives, food processing aids, seasoning production; Agriculture and feed industry: fertilizer raw materials, feed additives; Pharmaceutical and laboratory fields, pharmaceutical excipients, laboratory reagents; Textile printing and dyeing industry, water treatment industry, and daily chemical industry.

Potassium dihydrogen phosphate(DSP)

Disodium Hydrogen Phosphate (Na ₂ HPO ₄) and its hydrates are widely used in multiple industries due to their buffering, chelating, and nutritional supplementation properties. They can be used as commonly used food additives in the food industry, pharmaceutical industry, chemical and water treatment industry, agriculture and feed industry, and daily chemical industry. They are used as buffering agents in toothpaste, mouthwash, and other products. In the fields of biology and scientific research, they are used to prepare culture media and provide phosphorus sources for microbial growth; As an experimental buffer, it ensures the stability of biochemical reactions and cell culture.
