⭐ Product Overview
Polyether Polyol 3500, also known as PPG 3500, is a tri-functional polyether polyol with an average molecular weight of 3500, designed for use in the production of flexible polyurethane foam, slabstock foam, and a wide range of CASE applications (Coatings, Adhesives, Sealants, Elastomers). It is produced by the polymerization of propylene oxide (PO) with a glycerin initiator, resulting in a highly reactive and consistent polyol with excellent stability.
This grade provides optimum balance between softness, strength, and reactivity, making it widely used in mattresses, furniture foams, cushioning, and soft elastomeric PU systems. It is compatible with TDI, MDI, and polymeric MDI (PMDI) systems.
✅ Key Features & Advantages
🔬 Optimized Molecular Weight (3500) – Ideal for soft and medium-density foam formulations
🧪 Excellent Reactivity – Enhances processing speed and foam quality
💧 Low Moisture Content – Reduces side reactions and improves PU yield
