Coated slow-release urea

The latest generation of solvent-free bio based polyurethane packaging material (Chinese invention patent number: ZL202310002816.7) adopts bio based membrane material and introduces bio based polymer block copolymerization technology, which is environmentally friendly and biodegradable.

1. The membrane has good extensibility, stretchability, and elasticity, and is not easily worn or brittle during production, transportation, and fertilization processes

2. Continuous and stable nutrient release characteristics, meeting the long-term supply of crop nutrients, long fertilizer efficiency period, and no burning of roots or seedlings

3. The release period ranges from 30-180 days, suitable for various crops and customers' differentiated needs
