QHAD-A99 is a balanced blowing and gelation tertiary amine catalyst designed for flexible polyether polyurethane foams. It provides well‑balanced reactivity between water‑isocyanate blowing and polyol‑isocyanate crosslinking, supporting uniform cell structure, good flow, stable rise profile, and consistent physical properties. It is widely used in conventional slabstock foam, high‑resilience (HR) foam, and molded foam systems, offering broad processing latitude and compatibility with standard polyurethane additives.
