Description

Urea, Polymer With Acetaldehyde is a synthetic polymer derived from the condensation reaction of urea and acetaldehyde. This compound is valued for its ability to function as a controlled-release nitrogen source and as a versatile chemical intermediate in polymer synthesis. It is primarily utilized by manufacturers in the agricultural, specialty chemical, and resin industries seeking to enhance product performance and process efficiency.

Application

• Controlled-Release Fertilizers: Acts as a key component in slow-release nitrogen formulations for improved nutrient management in agriculture and horticulture.
• Amino Resin Modifier: Used in the production of urea-formaldehyde and melamine-formaldehyde resins to modify properties like flexibility, water resistance, and curing time.
• Adhesive & Binder Systems: Serves as a cross-linking agent or fortifier in wood adhesives, foundry sand binders, and paper coating formulations.
• Textile & Leather Processing: Employed as a resin finish for textiles to impart wrinkle resistance and as a tanning auxiliary in leather processing.
• Flame Retardant Additive: Incorporated into polymer composites and coatings to enhance flame-retardant properties.
• Water Treatment Chemicals: Functions as a precursor or component in certain ion-exchange resins and flocculants.

Quality Control

Our Urea, Polymer With Acetaldehyde is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as nitrogen content, solubility, and polymer chain characteristics. Certificates of Analysis (COA) documenting purity, physical properties, and performance indicators are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or property changes.
