Foaming does not occur in smooth surface coatings, or in the paper industry, and defoamers help control or completely prevent unwanted foam formation. HPSIL® specialty silica and HJSIL® fumed silica are important components of defoamer. They significantly increase efficiency and are often the only way to achieve the desired efficiency.
Our silica series products can meet:
Oily medium:
In oily medium such as mineral oil, silicone oil or vegetable oil, they can be used as anti-settling agentIndustrial defoamer and deaerator:
HJSIL® hydrophobic silica. Tailored granularity makes production easy.
Powder defoamers: HPSIL® specialty silica as carrier substance
Other Applications:
Insulation materials
