Emulsification is a process in which two immiscible liquids (water and oil) are mixed with an emulsifier and dispersed in continuous fine droplets, and the resulting solution is called an emulsion. Silicone emulsion generally consists of silicone oil, water, surfactant and other additives.
Silicone emulsion, which is made by dispersing silicone oil in water, is eco-friendly as water is used as a solvent instead of an organic solution. It can be used to manufacture various types of water-soluble products, and its demand is increasing steadily.
With low surface tension, silicone can be easily dispersed on complicated die surfaces. Excellent heat resistance and chemical inactivity have led to expanded applications to prevent attachment or adherence of ingredients to the die during pressure molding and injection molding of rubber and plastic.
Moreover, silicone is used in die casting molding process in which molten aluminum or nonferrous alloy is injected from meticulously processed mold at high speed and high pressure.
Silicone emulsion is used as a polish to increase exterior gloss and protect the surface.
By securing waterproofness and smooth surface, it is widely used as vehicles’ interior and exterior polish or tire polish.
Emulsion-type tire release agents do not contain fillers, thus, the mold has almost zero contamination. Also, with excellent releasing performance, it is used for molding tires of passenger vehicles and commercial vehicles to give semi-permanent releasing performance to the tire blender.
