Description
Coated Control Release Urea-The fifth generation Polymer-coated urea(PCU)
The ultrathin coating technology was applied to the granule. The product was tested by domestic and foreign research institutes, colleges and universities, and agricultural extension departments. The results indicate that the new generation polymer-coated urea enhanced urea use efficiency than that of conventional fertilizer.
Manufactured by the unique advanced technique and totally controlled by DCS central control system, the continuous processing line has been the highest level of automation, the highest productivity. The fifth generation PCU has the highest N content, thinnest coating, easily degradable and longest release period. The special manufacturing process gives each granule a durable and consistent coating. The products will give you and your customers superior fertilizer performance because of its unique, advanced coating technology. The product is better than that of national standard.

Benefits
High particle uniformity
The unique screening system is used to screen the large urea particles for the second time, and only the particles between 2.0-4.75mm are retained. The particle uniformity is high, and the controlled release effect is more stable.
Anti floating treatment
Anti-floating treatment can be carried out for products used in paddy fields. The highly efficient and environmentally friendly anti-floating technology can reduce the floating rate of fertilizer from 15% to 0%.
Longer release period
Generally, the controlled release period of resin-coated urea products is 2 months. By adjusting the formula of membrane materials, the controlled release period can be extended to 3-6 months under the same coating rate.
Degradable high-tech coating materials, continuously controlled supply of Nitrogen
The fifth-generation coating is easily degradable and high-tech, in special nitrogen-regular mode, providing a continuous and controlled supply of nitrogen with a typical “S” release curve. Nitrogen slow-release characteristics fit for target crops in different growth stages.
Higher Nitrogen content and Longer release longevity
The thin, durable, and consistent coating makes the product higher nitrogen content. And the PCU is good for producing kinds of BB fertilizers for different crops. The more consistent, durable coating means a more gradual, long-lasting release.
Environmentally friendly
The production process of PCU is clean and the coating degrades naturally and safely in time. It was solvent-free in the processing line. The product quality was stable and controlled. It’s healthy and stress-free for plant development and food safety. Using PCU practically avoids leaching or volatilization of nutrients. After the release is complete, the coating will degrade gradually, leaving no residues in the soil.
Highly efficient and economical
Apply only once and gain significant savings in labor costs and time. Lower transportation and warehousing costs. Less fertilizer is necessary to achieve optimum results.
