Rigid Foam Silicone Oil CGYM is a specialized silicone-based additive designed to control cell structure and improve the overall quality of rigid polyurethane foam. It functions primarily as a foam stabilizer and surfactant, optimizing the balance between cell opening and cell closing during the foaming process. This product is suitable for various rigid foam applications, including insulation boards, spray foam, refrigerators and freezers, sandwich panels, and construction insulation materials.

The product works by reducing surface tension between the polyol and isocyanate phases, promoting uniform mixing and consistent cell formation. It helps generate fine, evenly distributed cells, which contributes to improved thermal insulation performance, higher compressive strength, and enhanced dimensional stability of the finished foam. In many formulations, the use of this silicone oil can increase foam yield and reduce foam defects such as collapse, shrinkage, or uneven density.

Rigid Foam Silicone Oil CGYM is compatible with common blowing agents, including pentane systems and other physical or chemical blowing agents. It shows good adaptability across a wide range of formulations with different polyols, isocyanates, and catalysts. This flexibility makes it suitable for both high-density and low-density rigid foam systems, as well as for continuous and discontinuous production lines.

In processing, the product exhibits excellent flow and emulsification properties, helping to stabilize the foam at both the cream and rise stages. It supports stable production under varying temperature and humidity conditions, which is critical for maintaining consistent quality in industrial-scale manufacturing. The product can help reduce sensitivity to minor formulation fluctuations, providing a wider processing window and more robust operating conditions.

Typical benefits include improved cell fineness, better closed-cell content, reduced thermal conductivity, and enhanced surface appearance of foam products. It can also contribute to better adhesion to substrates in panel and spray applications, supporting bond strength and long-term durability. In systems where dimensional stability is critical, such as building insulation, this silicone oil helps minimize foam deformation over time.

Rigid Foam Silicone Oil CGYM is typically supplied as a clear to slightly hazy liquid, with good storage stability under normal conditions. It should be stored in a cool, dry place, away from direct sunlight and sources of heat. The product is usually metered directly into the polyol component and can be incorporated using standard mixing equipment.

Overall, Rigid Foam Silicone Oil CGYM offers an effective solution for producers seeking consistent, high-performance rigid polyurethane foams with improved insulation properties, mechanical strength, and processing stability.
