Features Of Sanyo Chemical SANNIX TP-400 Trimethylolpropane Polyether Polyol

  1. High functionality (f ≈ 3.0) derived from trimethylolpropane backbone, enabling robust crosslinking in polyurethane networks.

  2. Low color and low volatility, supporting stable processing and consistent final product aesthetics.

  3. Excellent hydrolytic stability due to ether linkage structure, enhancing durability in humid or demanding environments.

  4. Consistent molecular weight distribution (Mw/Mn ≤ 1.15), ensuring predictable reactivity and reproducible formulation performance.

  5. Low residual monomer content (< 0.1%), meeting stringent industrial safety and regulatory requirements for handling and end-use.

Typical Applications Of Sanyo Chemical SANNIX TP-400 Trimethylolpropane Polyether Polyol

  1. Flexible and semi-rigid polyurethane foams for automotive seating and interior components.

  2. High-performance polyurethane elastomers used in industrial rollers, seals, and wear-resistant parts.

  3. Coatings and adhesives requiring enhanced chemical resistance and mechanical toughness.

  4. Castable polyurethane systems for mining screens, pump liners, and heavy-duty tooling.

  5. Reaction injection molding (RIM) formulations where dimensional stability and impact strength are critical.
