QHAD-A300(Catalyst A300) Product Specification

1. Description

QHAD-A300(Catalyst A300) is a high-efficiency, multi-functional urethane catalyst specifically formulated for polyurethane foam manufacturing. As a key member of the Niax catalyst series, it exhibits excellent catalytic activity for both the gelation and blowing reactions in polyurethane systems, balancing the two reactions to ensure uniform foam structure and superior mechanical properties. This catalyst is a clear, colorless to pale yellow liquid with low viscosity, good compatibility with most polyurethane raw materials (including polyols, isocyanates, and other additives), and stable performance under typical industrial processing conditions. It is designed to enhance foam cell structure, improve foam flexibility and dimensional stability, and optimize processing efficiency, making it an ideal choice for a wide range of polyurethane foam applications.

3. Application

QHAD-A300(Catalyst A300) is widely applied in the production of various polyurethane foams, leveraging its balanced catalytic activity to meet the requirements of different foam types and processing technologies. Its key applications include but are not limited to:

• Flexible Polyurethane Foam: Suitable for manufacturing flexible foams used in furniture, mattresses, automotive seating, and cushioning materials. It helps form uniform, fine cell structures, improving foam softness, resilience, and durability.
• Rigid Polyurethane Foam: Applied in rigid foam production for thermal insulation, such as building insulation panels, refrigeration equipment insulation, and pipeline insulation. It enhances foam dimensional stability and insulation performance, while optimizing the foaming process to reduce production defects.
• Semi-Rigid Polyurethane Foam: Ideal for semi-rigid foams used in automotive interior parts (e.g., instrument panels, door panels) and packaging materials. It balances foam rigidity and flexibility, ensuring good processing fluidity and product shape retention.
• Polyurethane Elastomers: Used in the formulation of polyurethane elastomers, including cast elastomers and thermoplastic polyurethane (TPU), to control the curing rate and improve product mechanical properties such as tensile strength and abrasion resistance.
• Complementary Additive Use: Can be used in combination with other Niax catalysts, silicone stabilizers, blowing agents, and flame retardants to optimize foam performance, adapt to different raw material systems, and meet specific application requirements (e.g., low VOC, flame retardancy).

4. Storage

To maintain the catalytic activity and stability of QHAD-A300(Catalyst A300), strict adherence to proper storage conditions is essential. 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 10 °C to 25 °C; avoid storage in environments above 35 °C or below -70 °C, as extreme temperatures may affect product performance.
• Container Handling: Keep the original packaging containers tightly sealed when not in use to prevent moisture absorption, contamination, and volatilization. For partially used containers, purge the headspace with dry nitrogen before sealing to maintain product purity.
• Moisture & Ignition Source Avoidance: Keep the product away from water, moisture, and humid environments, as water contact may degrade its catalytic activity. Since it is flammable (flash point 82 °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-A300(Catalyst A300) is typically 12 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) to prevent chemical reactions.
• Note: For detailed safety precautions, handling guidelines, and environmental information, please refer to the Safety Data Sheet (SDS) of QHAD-A300(Catalyst A300). For technical support or further inquiries, contact the relevant customer service team.
