Product Spotlight: A33 Amine Catalyst Optimized For Polyurethane Flexible Foam Production

Oct 10, 2026 Leave a message

A33 amine catalyst is a widely adopted tertiary amine catalyst formulated with 33% triethylenediamine dissolved in dipropylene glycol, specially designed for polyurethane flexible foam applications such as sofa cushions, mattresses and molded automotive soft foam.

This product achieves well-balanced catalysis for both gel reaction and blowing reaction during foaming. It helps foam producers obtain stable rising profile, fine and uniform cell structure, and consistent physical properties of finished flexible foam. Compared with alternative amine catalysts, A33 features easy handling, good compatibility with polyol systems and stable catalytic activity under normal processing conditions.

Our flexible foam A33 catalyst undergoes strict quality inspection for each batch, guaranteeing consistent TEDA content and low impurity levels. It is packed in 35kg blue plastic drums. We can support small trial orders and bulk export shipments, together with full sets of shipping documents.

As global flexible foam manufacturers keep raising requirements on foam stability and production repeatability, high-quality A33 catalyst remains a fundamental additive for reliable PU foam formulation. Our technical team is available to assist customers in adjusting foam recipes to match different production lines and end-product specifications.
