Understanding WANOL F3147D Polyether Polyol
WANOL F3147D Polyether Polyol is a polyether-based polyol developed for the production of flexible polyurethane foam. It reacts with isocyanates such as TDI and polymeric MDI to form a polymer network that gives the foam its softness, elasticity, and ability to recover its shape. Formulators turn to WANOL F3147D Polyether Polyol when a stable reactivity profile and predictable foam rise are priorities on continuous or batch production lines.
As a supply partner in the polyurethane raw materials market, DOMI (HK) INDUSTRIAL CO., LIMITED is an officially authorized distributor of world-class polyurethane manufacturers, including Covestro, Wanhua Chemical, Cangzhou Dahua, and Gansu Yinguang. With annual sales exceeding 50,000 metric tons and customers in more than 30 countries , DOMI (HK) INDUSTRIAL helps foam manufacturers secure stable and cost-effective supplies of polyether polyols.
Key Advantages of WANOL F3147D Polyether Polyol
- Consistent hydroxyl functionality, delivering predictable crosslink density and foam firmness.
- Good compatibility with standard catalyst, surfactant, and blowing agent packages.
- Stable viscosity, enabling accurate metering and mixing during high-output foaming.
- Helps produce foam with balanced resilience, load-bearing capacity, and comfortable feel.
- Characteristics: low color and odor, which allow finished products to meet indoor air quality expectations.
Because WANOL F3147D Polyether Polyol is designed with foam consistency in mind, converters can often reduce scrap rates and achieve tighter control over density and firmness across production batches.
How WANOL F3147D Polyether Polyol Works in Foam
Reaction Mechanism
The hydroxyl (-OH) groups on WANOL F3147D Polyether Polyol react exothermically with isocyanate (-NCO) groups to form urethane linkages, building the polymer backbone of the foam. At the same time, water in the formulation reacts with the isocyanate to release carbon dioxide, which expands the mixture into a cellular structure. The relative rate of this gelling reaction compared with the blowing reaction determines cell opening, rise height, and overall foam stability.
