从China供应商批发进口A-1 — FOB条款

A-1 is a colourless liquid amine catalyst specifically formulated for polyurethane foam production, offering high catalytic activity and selectivity for foaming reactions. Its composition includes 69.60-70.40% BDMAEE content and 30.6-31.4% DPG content, with a density of 0.9 g/cm³ at 20°C and a flash point of 74°C, making it suitable for controlled exothermic processes. The product contains less than 0.5% water, ensuring stability in moisture-sensitive applications.

This catalyst is designed for polyurethane systems, particularly HR, semi-rigid, and low-density foams, where precise reaction control is critical. The typical industry standard for amine catalysts in this category includes a density range of 0.85-1.05 g/cm³, a flash point above 60°C, and water content below 1% to prevent side reactions. A-1 meets these benchmarks while providing enhanced selectivity for isocyanate-water reactions, a key factor in foam cell structure formation.

Polyurethane foam manufacturers, especially those producing mattresses, automotive seating, and insulation panels, use A-1 to achieve consistent cell opening and foam rise profiles. The catalyst is packaged in 170 kg drums and has a shelf life of at least 12 months when stored in dry, cool, and well-ventilated conditions with containers tightly sealed. Buyers should confirm compatibility with their specific foam formulations, as amine catalysts can vary in reactivity depending on the polyol and isocyanate systems used.

Shijiazhuang Hehui Chemicals Co., Ltd. is based in Jinzhou Circular Industrial Park, Shijiazhuang, Hebei Province, China. The company specialises in the production of amine catalysts for polyurethane applications, with a focus on formulations that enhance foaming reactions in industrial settings. Its location in a designated chemical park suggests access to logistical infrastructure tailored for bulk chemical handling.

The supplier operates within the Harbor trust tier, indicating a baseline level of verified business information. While the response rate is currently listed as 0.00%, this may reflect recent data or a temporary gap in communication tracking. The company’s product descriptions are technical and specific, aligning with its role as a catalyst manufacturer rather than a broad chemical distributor.
