Silicone Surfactant L580 is a high-efficiency organosilicon surfactant specifically designed for polyurethane (PU) foam systems, with superior bubble structure regulation as its core advantage. Its unique molecular structure significantly reduces the surface tension of resin systems, promoting even gas dispersion and bubble growth while endowing foam materials with a fine cellular structure and excellent resilience. Whether for mass production of ordinary sponges or high-end manufacturing of slow-recovery memory foam, L580 optimizes bubble morphology to enhance the mechanical properties and tactile experience of final products, making it an indispensable functional additive in modern polyurethane industry.
| Indicator | Specification | Industry Value Interpretation |
|---|---|---|
| Appearance | Colorless or light yellow transparent liquid | Visual judgment of product purity and homogeneity; no turbidity or layering indicates good storage status |
| Viscosity (25℃, mPa·s) | 800–1250 | Affects mixing uniformity and fluidity; moderate viscosity facilitates industrial pumping and metering |
| Specific Gravity (25℃, g/cm³) | 1.00–1.04 | Correlates with addition accuracy; stable density ensures consistency between batches |
| pH | 4.5–7.0 | Reflects acid-base balance; neutral to weakly acidic avoids corroding equipment or affecting resin reactions |
| Cloud Point (℃) | 37–42 | Determines the temperature window for foaming; higher cloud point adapts better to stable bubble formation in high-temperature environments |
| Refractive Index | 1.44 | Auxiliary verification of chemical composition consistency |
| Water Content (%) | ≤0.15 | Low moisture content prevents hydrolysis and maintains catalytic activity |
L580 is primarily used for the preparation of ordinary sponges and slow-recovery gas-filled polyurethane foam plastics. Its key functions include:
