Polyether L-63 (CAS No.: 9003-11-6) belongs to the poloxamer nonionic surfactants. It appears as a colorless to slightly yellow transparent viscous liquid. Its molecular structure endows the product with excellent surface-active properties, integrating multiple functions such as emulsifier, wetting agent, dispersant, leveling agent, and softener, making it an indispensable key raw material in the polyurethane industry.
In terms of chemical resistance, polyether L-63 has good resistance to acids, alkalis, and hard water, meaning it can maintain stable performance under complex process conditions and is not easily affected by water quality or pH fluctuations. At the same time, it has excellent foam stability and high processing tolerance, allowing producers to achieve ideal foaming effects over a wide range of process parameters, reducing the difficulty of process control.
From the perspective of final product performance, polyether L-63 can impart uniform cell structure and excellent resilience to the products. This characteristic makes it outstanding in applications such as polyurethane high-resilience flexible foams (e.g., car seats, furniture cushions), self-skinning foams (e.g., steering wheels, armrests), semi-rigid foams (e.g., dashboard fillings), and microcellular elastomers (e.g., shoe soles, shock-absorbing pads). In addition, as a polyol component in two-component polyurethane adhesives and coatings, it can effectively improve the adhesion, flexibility, chemical resistance, and weatherability of the system.

The core applications of polyether L-63 are concentrated in the following five areas:
Handling Protection: It is recommended to wear chemical protective gloves (nitrile or neoprene gloves) and chemical safety goggles during operation to avoid contact with eyes and skin. After operation, thoroughly wash hands and exposed skin.
Storage Conditions: Store in a cool, dry, well-ventilated warehouse. Recommended temperature 5–40°C. Keep containers tightly closed. Keep away from incompatible materials such as strong oxidizers and strong acids. Avoid freezing or prolonged exposure to high temperature.
Emergency Measures: In case of eye contact, immediately flush with plenty of water for several minutes. If wearing contact lenses, remove them and continue flushing. If irritation persists, seek medical attention. For skin contact, wash thoroughly with water and soap. In case of spillage, collect with inert absorbent material and prevent entry into drains or waterways.
