Innonew Material’s Polyvinyl Alcohol PVA (PVOH) 2488 powder is a water-soluble polymer widely used as a binder, film former, and coating agent across industrial applications. In the fertilizer industry, PVA 2488 offers a practical, high-performance solution for granulation, dust suppression, controlled-release coatings, and pellet strength enhancement. Its combination of strong adhesion, ease of dissolution, and favorable environmental profile makes it especially attractive where product quality and sustainability matter.
PVA 2488 is supplied as a fine, white powder that dissolves readily in warm water to form clear, viscous solutions. It is formulated to deliver consistent viscosity and excellent film-forming ability, yielding flexible, uniform coatings. As a binder in granulation, PVA 2488 improves particle integrity and reduces friability without negatively affecting nutrient composition. Important practical attributes include good cold-weather performance when used with the right plasticizers, low odor, and compatibility with commonly used fertilizer additives.
Functions in fertilizer production
• Granule binder — PVA 2488 binds powdery ingredients into durable granules during pan or drum granulation, improving bulk density and reducing fines that cause product loss and operational dust.
• Dust suppression — Applied as a light surface spray, PVA solutions form a thin film that locks down fine particles on finished granules, improving handling and worker safety.
• Coating and slow-release matrix — Because it forms continuous films, PVA 2488 is an effective base for coating nutrient granules. When combined with biodegradable additives or inorganic fillers, it contributes to controlled nutrient release profiles, reducing leaching and improving fertilizer efficiency.
• Pellet strength and transport stability — PVA improves mechanical strength, reducing breakage during bagging, transit, and storage.
Environmental and sustainability advantages
PVA 2488 supports greener fertilizer production in several ways. Its water solubility allows processing without organic solvents. When formulated appropriately, PVA films can be designed to degrade under environmental or microbial action, enabling more sustainable controlled-release systems than some petroleum-based coatings. By reducing fines and improving nutrient use efficiency (less runoff and volatilization), PVA-bound fertilizers can contribute to lower environmental impact over the product life cycle.
PVA 2488 powder is a versatile, effective binder and coating agent that helps fertilizer producers improve product quality, handling, and performance while supporting more sustainable practices. When combined with proper testing, regulatory compliance, and responsible handling procedures in China, PVA 2488 enables manufacturers to produce reliable, environmentally sensitive fertilizer products that meet modern agronomic and regulatory demands.
