SI8921

Product Introduction

SI8921 is a silicon-carbon bond non-hydrolyzable silicone surfactant. Specially designed for use in hard foam formulations like those with very low activity and difficult to stabilize. In such formulations, SI8921 is effective in maintaining the compatibility of the foam components. SI8921 provides excellent flow in high water/low physical blowing agent formulations.

Product Characteristics

In HCFC/HFC/pentane system, providing good compressive strength and dimensional stability;

●Good emulsifying performance, improve system compatibility;

In the slow reaction rigid foam system, to provide chemical stability and compatibility;

● It can produce uniform and detailed cell structure;

● The recommended addition amount is about 1.2-3%, which needs to be adjusted accordingly based on the formula.
