We are offering Ammonium Sulphate. cas no.: 7783-20-2 molecular formula: (nh4)2so4 molecular weight:132.14 properties: ammonium sulphate has ph value is 5.5 in 0.1m solution. density 1.769 g/cm3 (20°c). ammonium sulphate is hygroscopic; soluble in water; insoluble in acetone, alcohol and ether. main active ingredients are 21% nitrogen and 24% sulfur, so it can be described as npk 21-0-0 24s. generally, it is a by-product from chemical (cyanuric acid, capro, acrylonitrile, sodium cyanide, monosodium glutamate-msg, methyl methacrylate-mma, etc.) or steel plant. steel grade (also call coke-ovens grade) is fine white powder. after processing it can be white granular or flake. caprolactam grade is colorless (achromatic) crystalline or yellowish crystals. packing: 20kg, 25kg, 50kg pp woven bag with pe inner bag or composite plastic woven bag.1mt (1000kg) or 1.1mt (1100kg) jumbo bag. shrink-wrapped with pallet is available. kept in dry and place, avoid moisture, water, rain and fire, normal transportation. in the transportation and outdoor storage, ammonium sulphate should be kept away from moisture, insolation, rain&high temperature. should storage in flatness ground within a ventilating low-temperature dry warehouse. in order to prevent deterioration, strictly prohibit store nearby alkaline substances, such as lime, cement and plant ash. the stacking height should be less than 7 meters.

We are offering urea. cas no.: 57-13-6 molecular formula: ch4n2o molecular weight: 60.06 properties: urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. Urea is solid, colorless, and odorless (although the ammonia that it gives off in the presence of water, including water vapor in the air, has a strong odor). Urea is highly soluble in water and practically non-toxic (ld50 is 15 g/kg for rat). Dissolved in water, it is neither acidic nor alkaline. The body uses urea in many processes, the most notable one being nitrogen excretion. Urea is widely used in fertilizers as a convenient source of nitrogen. Urea is also an important raw material for the chemical industry. usage: in the past decade urea has surpassed and nearly replaced ammonium nitrate as a nitrogen fertilizer. Urea is also widely used in the agricultural industry as an animal feed additive. urea fertilizer can be coated with certain materials, such as sulfur, to reduce the rate at which the nitrogen becomes available to plants. Under certain conditions these slow-release materials result in more efficient use by growing plants. Urea in a slow-release form is popular for use on golf courses, parks, and other special lawn situations.
