The appearance of A D C foaming agent is yellow to light yellow powder. The finer the particles, the lighter the color. The specific gravity (water = 1) is 1.65, which is flammable but does not support combustion. It is the most economical and widely used organic chemical foaming agent in industrial applications. It is an exothermic foaming agent.Mainly used to produce closed-cell rubber and plastic foam products. Ordinary ADC decomposes at a temperature of 200~220°C. In order to meet the requirements of rubber and plastic processing, the decomposition temperature is usually adjusted by adding special additives.
| Parameter | Specification/Description |
| Molecular Formula | C2H4O2N4 |

| Decomposition Byproducts | Nitrogen gas (N2, ~65%), carbon mo noxide (CO), carbon dioxide (CO2), am monia (NH3), etc. |
| Residues | Trace amounts of urazole, biurea (residues must be controlled to avoid odor/pollution) |
| pH (aqueous suspension) | 6.0-8.0 |
| Solubility | Insoluble in water; slightly soluble in polar organic solvents (e.g., DMF, DMSO) |
| Parameter | Typical Range/Notes |
| Gas Emission | 190-220 mL/g (STP) |
| Particle Size (D50) | 5-20 μm (customizable for ultrafine or coarse particles based on process needs) |
| Decomposition Temp. Adjustment | Activators (e.g., zinc oxide, zinc stearate) adjust decomposition temp. to 150-190°C |
| Decomposition Rate | Rapid gas release (suitable for continuous extrusion/molding processes) |
| Residue Content | <1% (controlled based on product requirements) |
| Toxicity | Decomposition byproducts may include trace CO/NH3 (ventilation required); raw material dust may irritate airways (see MSDS). |
| Grade Type | Decomposition Temp. (°C) | Gas Yield (mL/g) | Applicable Process | Features |
| Standard ADC | 195-220 | 200-220 | High-temp extrusion/molding | High gas yield, versatile |
| Low-Temp ADC | 150-180 | 180-200 | Low-temp foaming (e.g., PVC boards) | Energy-efficient with activators |
| Ultrafine ADC | 195-220 | 200-220 | High-precision microcellular foaming | D50 <10 μm, excellent dispersion |
(1)Activator Selection: Use zinc oxide, zinc stearate, etc. Test compatibility with formulations.
(2)Temperature Matching: Ensure decomposition temperature aligns with processing conditions to avoid premature/delayed foaming.
(3)Residue Control: Excess residues may cause yellowing/odor; optimize formulations and processes.
(4)Safety Compliance: Dust is explosive (use explosion-proof equipment); ventilate decomposition gases (monitor CO).
