QHS-5823 Product Datasheet

Silicone Surfactant QHS-5823 is a registered trademark of Shijiazhuang Qihong New Material Technology Co.,Ltd.

1. Description

Silicone Surfactant QHS-5823 is a high-performance silicone surfactant specifically developed for ultra-low density flexible polyether polyurethane foams. As a key additive in polyurethane formulations, it plays a critical role in stabilizing the foam cell structure, ensuring uniform cell distribution and excellent foam quality even at the lowest density levels.

Its unique molecular structure endows it with maximum stabilization efficiency, making it the preferred choice for high-demand foam applications where precision, consistency, and reliability are essential. The product is fully compatible with both MDI (Methylene Diphenyl Diisocyanate) and TDI (Toluene Diisocyanate)-based foam systems, providing formulators with greater flexibility in formulation design while maintaining a stable foaming process from start to finish.

2. Specification

3. Application

3.1 Primary Application Fields

• Ultra-low density flexible foams (15–25 kg/m³) for furniture padding, bedding, and packaging materials.
• High-resilience (HR) slabstock foams that require a fine, uniform cell structure for superior performance.
• Specialized foam products where consistent cell morphology, minimal surface defects, and long-term stability are critical.

3.2 Key Performance Advantages

• Exceptional Stabilization: Delivers maximum stabilization efficiency for ultra-low density foams, preventing cell collapse and ensuring structural integrity throughout the foaming process.
• Superior Cell Structure: Produces fine, regular cell structures with reduced pinholes, surface irregularities, and defects, enhancing both the aesthetics and mechanical properties of the foam.
• Broad Formulation Compatibility: Works effectively with a wide range of polyol formulations, including natural oil-based polyols (NOPs), offering flexibility for diverse production needs.
• Low Emission Profile: VOC-optimized formulation with low cyclic siloxane content, meeting stringent indoor air quality standards (e.g., IKEA IOS Mat 0010 V15) and environmental regulations.

4. Storage

• Storage Environment: Store in a cool, dry, and well-ventilated area, away from direct sunlight, open flames, and other ignition sources.
• Temperature Range: Recommended storage temperature is 15–30°C (59–86°F). Avoid exposure to temperatures below 5°C (41°F) or above 40°C (104°F) to prevent product degradation.
• Container Integrity: Keep the original container tightly sealed when not in use to prevent moisture absorption, contamination, and volatilization of active ingredients.
• Shelf Life: 12 months from the date of manufacture when stored under the recommended conditions.
• Handling Precautions: Wear appropriate personal protective equipment (PPE), including gloves and safety goggles, during handling. Avoid inhalation of vapors and prolonged skin contact. In case of contact, rinse thoroughly with water.
