Modified ethylene urea formaldehyde scavengers are modified ethylene urea to more effectively capture and remove formaldehyde. Ethylene urea itself is a formaldehyde scavenger, but modifications can enhance its performance, such as increasing its formaldehyde capture rate, increasing its capture capacity, or improving its suitability for specific environments.
| Name | Modified ethylene urea formaldehyde scavenger |
| Appearance | White needle-shaped crystals or powder |
| Solubility | Easily soluble in water (950g/L) and hot ethanol; aqueous solution is weakly alkaline (pH ≈ 9 for a 20% solution) |
| Thermal Stability | Resistant to high-temperature decomposition |
| Melting Point | 128-133°C |
| Flash Point | 265°C |
| Permanence | The reaction product is stable and does not readily release formaldehyde |
| Applicable pH Range | Effective in acidic to alkaline environments (pH 3-9) |
| Safety | Low toxicity; avoid direct contact |
| Storage | Store in a cool, dry place |
Applications of Modified Ethylene Urea Formaldehyde Scavengers:
Artificial Boards:
Adding this agent during the production process effectively reduces the free formaldehyde content in the boards, improving indoor air quality.
Coatings:
Adding this agent to coatings reduces formaldehyde emissions, reducing indoor air pollution.
Textiles:
Adding this agent during the textile finishing process reduces formaldehyde content in textiles, improving their safety.
Other Applications:
It can also be used in indoor air purification, water treatment, and other fields.
