QHAD-A400 Product Specification

1. Description

QHAD Catalyst A-400 is a high-performance, amine-based urethane catalyst specifically engineered for polyurethane foam production, belonging to the premium Niax catalyst series. It is uniquely formulated to exhibit strong catalytic selectivity for the blowing reaction (water-isocyanate reaction) while maintaining moderate gelation activity, ensuring optimal balance between foam expansion and cell structure formation. This catalyst appears as a clear, pale yellow to amber liquid with low viscosity, excellent compatibility with all common polyurethane raw materials—including polyols, isocyanates, silicone stabilizers, and blowing agents—and outstanding stability under industrial processing temperatures (20-80 °C). Niax Catalyst A-400 is designed to enhance foam expansion efficiency, improve cell uniformity, and boost the overall mechanical strength of finished foam products, making it a reliable choice for high-demand polyurethane foam manufacturing scenarios.

3. Application

QHAD Catalyst A-400 is primarily used in polyurethane foam production, leveraging its strong blowing reaction selectivity and balanced catalytic performance to meet the needs of various foam types and industrial processing technologies. Its key applications include but are not limited to:

• Rigid Polyurethane Insulation Foam: Particularly suitable for manufacturing rigid foam used in building insulation, refrigeration equipment, and pipeline insulation. It promotes efficient foam expansion, forms a dense and uniform cell structure, and enhances the foam’s thermal insulation performance and dimensional stability, reducing energy loss in end products.
• Flexible Polyurethane Foam: Applied in the production of flexible foams for mattresses, furniture cushions, and automotive seating. It helps optimize cell size distribution, improving foam softness, resilience, and durability, while ensuring consistent foaming quality in large-scale production.
• Spray Polyurethane Foam (SPF): Ideal for spray foam applications in building envelopes, roof insulation, and cavity filling. Its balanced gelation and blowing activity ensures good sprayability, rapid curing, and strong adhesion to various substrates, forming a seamless insulation layer.
• Polyurethane Foam Composites: Used in the formulation of polyurethane foam composites, such as foam-core panels and structural foam, to enhance the composite’s mechanical strength, impact resistance, and dimensional stability.
• Complementary Additive Use: Can be combined with other Niax catalysts (e.g., gelation-focused catalysts)、silicone surfactants, and flame retardants to tailor foam performance, adapt to different raw material systems, and meet specific industry requirements such as low VOC emissions and flame retardancy.

4. Storage

To preserve the catalytic activity and chemical stability of QHAD Catalyst A-400, strict compliance with proper storage conditions is mandatory. The key storage requirements are as follows:

• Storage Environment: Store in a dry, cool, and well-ventilated warehouse, away from direct sunlight, high temperatures, and moisture. The recommended storage temperature range is 8 °C to 25 °C; avoid storage in environments above 40 °C or below -65 °C, as extreme temperatures may degrade product performance or cause physical changes.
• Container Handling: Keep the original packaging containers tightly sealed when not in use to prevent moisture absorption, contamination, and volatilization of active components. For partially used containers, purge the headspace with dry nitrogen before sealing to maintain product purity and stability.
• Moisture & Ignition Source Avoidance: Keep the product away from water, moisture, and humid environments, as water contact may reduce its catalytic activity. Since it is flammable (flash point 88 °C), keep it away from ignition sources such as heat, sparks, open flames, and electrical equipment with potential sparks.
• Shelf Life: When stored in unopened original containers under the recommended conditions, the shelf life of QHAD Catalyst A-400 is typically 12-18 months from the date of manufacture. Always check the "use before" date printed on the product packaging for specific validity information.
• Equipment & Handling: Use clean, dry, and corrosion-resistant equipment (e.g., stainless steel, glass, Teflon) for handling and transferring the product. Avoid contact with incompatible materials (e.g., strong acids, strong bases, oxidizing agents) to prevent chemical reactions and product degradation.
• Note: For detailed safety precautions, handling guidelines, and environmental information, please refer to the Safety Data Sheet (SDS) of Niax Catalyst A-400. For technical support or further inquiries, contact the relevant customer service team.
