Polymer Coated Urea Description
The polymer coated urea (PCU) produced by Risso Fertilizer Factory has national patent technology in China, and the product meets the Q/DYC01-2015 standard.
Polymer coated urea (PCU) consists of a core layer and a coating layer. The core layer is granular urea, and the coating layer is two layers. The inner layer is a shrink layer, and the outer layer includes polyurethane and raw materials polymerized by polyols and oil substances with co-bonded double bonds.
Polymer coated urea (PCU) is a safer and more efficient nitrogen source. Its release rate is mainly determined by temperature and moisture through the micropores in the coating, which is usually called temperature-controlled diffusion and osmotic pressure. It can also be called a smart release nitrogen fertilizer that can provide nutrients to your plants throughout the season. The shelf life of PCU urea is 3-12 months.
PCU UREA Advantages:
- High particle uniformity A unique screening system is adopted to screen the large-particle urea for a 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.
- Can do anti-floating treatment The products used in paddy fields can be treated with anti-floating treatment, and the efficient and environmentally-friendly anti-floating technology can reduce the floating rate of fertilizer from 15% to 0%.
- 3.Longer controlled release period Generally, the controlled release period of resin-coated urea products is 2 months. By adjusting the film material formula, the controlled release period can be extended to 3-6 months under the same coating rate.

How does Risso ensure the quality of urea fertilizers?
1. Before production: Risso will set up a strict production plan, determine the quality of urea and process requirements, provide the necessary resources for the process and determine the key production processes (production equipment, key process points, key quality requirements of the process products) to establish self-inspection and mutual inspection between teams.
2. During the production process: we keep in communication with customers at any time, we can provide customers with videos or photos of the urea production process, to ensure that customers have no worries.
3 . Before delivery: Before shipment, we will ask the third party organization to issue the test report of urea fertilizer according to the requirements specified by customers.
