Silicone Surfactant L580

Silicone Surfactant L580

It is an organic silicone surfactant with a fine cell structure. It is mainly used for the preparation of ordinary sponges and slow-expanding rebounding sponge polyurethane foam plastics, and has the characteristics of fine cell structure and wide tolerance range.
Product Details

I. Product Overview

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.

IndicatorSpecificationIndustry Value Interpretation
AppearanceColorless or light yellow transparent liquidVisual judgment of product purity and homogeneity; no turbidity or layering indicates good storage status
Viscosity (25℃, mPa·s)800–1250Affects mixing uniformity and fluidity; moderate viscosity facilitates industrial pumping and metering
Specific Gravity (25℃, g/cm³)1.00–1.04Correlates with addition accuracy; stable density ensures consistency between batches
pH4.5–7.0Reflects acid-base balance; neutral to weakly acidic avoids corroding equipment or affecting resin reactions
Cloud Point (℃)37–42Determines the temperature window for foaming; higher cloud point adapts better to stable bubble formation in high-temperature environments
Refractive Index1.44Auxiliary verification of chemical composition consistency
Water Content (%)≤0.15Low moisture content prevents hydrolysis and maintains catalytic activity

III. Application Fields

L580 is primarily used for the preparation of ordinary sponges and slow-recovery gas-filled polyurethane foam plastics. Its key functions include:

  • Regulating bubble size and distribution to achieve a fine, uniform cellular structure.
  • Enhancing foam resilience and compression recovery, especially critical for memory foam applications.
  • Broadening the tolerance range of foam formulations, reducing sensitivity to raw material variations and processing conditions.

IV. Storage and Transportation Guidelines

To preserve L580’s performance, follow these protocols:

  • Temperature: Store at 0–40℃. Avoid extreme temperatures (<0℃ may cause viscosity changes; >40℃ accelerates degradation).
  • Environment: Keep in a cool, dark, sealed, and dry place. Protect from water and moisture—prolonged exposure may reduce effectiveness.
  • Handling: Do not store in open containers. Wear necessary protective equipment (safety goggles, work clothes, rubber gloves) during operation, as long-term contact may irritate skin and respiratory tracts.

V. Technical Support

For detailed application guidance (e.g., dosage optimization, troubleshooting foam defects) or custom solutions, contact Shijiazhuang Qihong Technical Service. We provide:

  • Free lab-scale trials to validate L580’s suitability for your specific foam system.
  • On-site process audits to identify bottlenecks in PU foam production lines.
  • Tailored recommendations for blending L580 with other additives (e.g., catalysts, blowing agents) to maximize performance.

L580’s precision in bubble control and adaptability to diverse PU foam types make it a trusted choice for manufacturers seeking consistent quality and enhanced product value. Whether scaling up sponge production or developing next-generation memory foam, rely on L580 to deliver superior cellular structures and user experiences.
