Deep Description of WynPUF® XH-1613 Foam Stabilizer
WynPUF® XH-1613 is a specialized foam stabilizer designed to optimize the performance of rigid polyurethane foam systems, particularly those using pentane as the primary blowing agent. Below is an in-depth breakdown of its properties, applications, and advantages.
1. Product Overview
WynPUF® XH-1613 is a Si-C bond, non-hydrolytic polysiloxane polyether copolymer, making it highly stable and effective for rigid polyurethane (PU) foaming applications. This molecular structure ensures resistance to hydrolysis, meaning the stabilizer remains intact and effective in a variety of environmental conditions, including exposure to moisture.
2. Physical Properties
- Appearance: A clear liquid, ensuring easy handling and visual quality checks.
- Viscosity (at 25℃): 600-1200 cp, indicating a moderate fluidity suitable for uniform mixing with polyols.
- Moisture Content: ≤0.3%, signifying excellent stability and low risk of unwanted side reactions due to water.
- pH (1% aqueous solution): 6.0 ± 1.0, reflecting a near-neutral pH that prevents compatibility issues or adverse reactions in polyurethane formulations.
3. Key Features
- Cell Structure Optimization: WynPUF® XH-1613 creates a fine and uniform foam cell structure, which is crucial for maintaining low thermal conductivity in insulation applications such as refrigerators.
- Enhanced Material Flow: This stabilizer facilitates a high flow of foaming material, leading to:
- Better density distribution across the foam.
- Superior strength distribution in the final product.
- Reduction of surface defects like cavities or voids.
- Improved Thermal Performance: The resulting foam exhibits low thermal conductivity, improving energy efficiency in insulation systems.
4. Applications
WynPUF® XH-1613 is particularly suitable for rigid polyurethane foam systems used in high-end applications, including:
- Refrigerators and Freezers: It ensures consistent foam density and insulation properties, critical for thermal efficiency.
- Other Rigid Foam Systems: Ideal for industrial or commercial insulation requiring precision and durability.
5. Usage Recommendations
- Dosage: The recommended dosage is 2.0 to 3.0 parts per hundred of polyol (php), a common range for foam stabilizers in high-performance systems.
- Blowing Agent Compatibility: Designed to function optimally in pentane-based foaming systems, supporting both environmental sustainability and cost-efficiency.
6. Packaging and Storage
- Packaging: Delivered in 200 kg drums, ensuring easy transportation and sufficient supply for industrial-scale operations.
- Storage Stability:
- The product has a shelf life of 24 months when stored in closed containers.
- Recommended storage conditions: Cool, dry environments, away from moisture and direct sunlight to maintain product integrity.
7. Advantages of WynPUF® XH-1613
- Eco-Friendly: Its compatibility with pentane-based systems supports the transition to more sustainable blowing agents.
- High Performance: Delivers consistent, high-quality foam for demanding applications.
- Process Efficiency: Simplifies production by improving flow, minimizing defects, and enhancing thermal performance.
Conclusion
WynPUF® XH-1613 is a cutting-edge foam stabilizer tailored for high-end rigid polyurethane applications where thermal insulation, structural integrity, and process efficiency are critical. Its robust formulation ensures excellent performance in pentane-based systems, making it a preferred choice for premium appliances and industrial insulation solutions.
