In the field of polymer materials manufacturing, azodicarbonamide (ADC) blowing agent has become the core technology to promote lightweight and efficient production by virtue of its unique chemical properties and process adaptability. This article comprehensively analyzes how ADC can reshape the modern foaming industry and help realize the goal of sustainable manufacturing from technical principles, production processes to industrial applications, and highlights the professional solutions of Shuntai Tech, a leading company in the industry.
Molecular mechanism for precise foam control
The foaming behavior of ADC results from the synergistic action of azo bonds and amide groups in its molecular structure. When the temperature rises to a critical range, the molecular chains break and release a mixture of gases, a process that can be modulated by a catalyst to achieve a wide temperature response of 160-220°C. The gas molecules in the polymer melt can then be released into the melt and the gas molecules are released into the melt. In the polymer melt, the gas molecules form initial bubble nuclei, and by optimizing the cooling rate and in-mold pressure, a closed-pore structure with a uniform pore size distribution is achieved. This precise control allows ADC to meet a wide range of needs, from low-density packaging materials to high-strength structural components, providing great flexibility in product design.
Triple breakthrough in environmental performance
ADC blowing agent's innovations in the field of environmental protection are:
Low toxicity formulation: Through strict raw material selection and process control, the product complies with EU regulations and the heavy metal content is far below international standards.
Low Ammonia Emission Technology: Through molecular structure modification, ammonia emission is significantly reduced compared to traditional products to meet indoor air quality requirements.
Adaptation to circular economy: ADC Foam's polymer materials can be recycled through physical recovery or chemical depolymerization, helping customers to achieve sustainable development goals.
Raw Materials Preparation
The primary raw materials for ADC production are urea and hydrazine hydrate.
These materials are carefully measured and prepared for the synthesis process.
Synthesis of Hydrazodicarbonamide (HDCA)
Urea and hydrazine hydrate react under controlled conditions to form hydrazodicarbonamide (HDCA).
The reaction is typically carried out in an aqueous solution at elevated temperatures (around 100°C).
Oxidation to Azodicarbonamide (ADC)
HDCA is then oxidized to form azodicarbonamide (ADC).
Common oxidizing agents include chlorine, sodium hypochlorite, or hydrogen peroxide.
The reaction is exothermic and requires careful temperature control to ensure safety and product quality.
Purification and Washing
The crude ADC product is washed and purified to remove impurities and by-products.
This step ensures the final product meets industry standards for purity and performance.
Drying and Particle Size Control
The purified ADC is dried to remove residual moisture.
The product is then milled or sieved to achieve the desired particle size, which is critical for specific applications.
Modification (Optional)
Depending on the application, ADC may be modified to enhance its properties, such as activation temperature or gas yield.
Common modifications include surface treatment or blending with other additives.
Temperature Control: Precise control of reaction temperatures is essential to avoid decomposition or side reactions.
Oxidizing Agent Selection: The choice of oxidizing agent affects the efficiency and environmental impact of the process.
Safety Measures: ADC production involves hazardous chemicals, so proper safety protocols must be followed.
