QHAD-225 Product Data sheet

1. Description

QHAD-225 is a delayed‑action tertiary amine catalyst specially developed for high‑resilience (HR) molded polyurethane foams in TDI and TDI/MDI blended systems. It balances blowing and cross‑linking reactions, improves flowability of reaction mixtures, shortens demolding time, and boosts line efficiency. It is widely used in high‑speed rotary table production lines while maintaining excellent foam physical properties and processing stability.

2. Specification

Typical values are for reference only and do not constitute a binding specification.

3. Application

• Delayed‑action catalyst for high‑resilience molded polyurethane foam
