Polyurethane-coated films have advantages over other coating films in controlled-release fertilizers, such as thinner thickness, shorter degradation time, lower cost, and better degradability, making them more competitive in large-scale field applications.
Specifically, the advantages of polyurethane-coated films include:
Polyurethane-coated films can achieve a thinner thickness. For example, a fertilizer technology article pointed out that the coating film thickness of Maoshi polyurethane controlled-release fertilizer is only one-third of that of similar products in Japan, which directly reduces production costs.
Polyurethane-coated films have a shorter degradation time in soil, reducing environmental residues and negative impacts.
Due to the reduction in coating film thickness and the improvement in degradability, polyurethane-coated films have advantages in reducing production costs, making the large-scale application of controlled-release fertilizers possible. According to Maoshi fertilizers, Maoshi polyurethane controlled-release fertilizer technology is at the world-leading level in this regard.
Polyurethane-coated films, especially those based on vegetable oil, have good degradability, reducing environmental pollution.
Improved nitrogen utilization efficiency:
Polyurethane-coated fertilizer can reduce nitrogen volatilization and leaching, improving utilization efficiency and reducing environmental pollution.
In summary, polyurethane-coated films have significant advantages in the field of controlled-release fertilizers, making them a promising coating material choice.
