What is a silicone defoamer?
A silicone defoamer is a chemical additive made from silicone-based compounds designed to eliminate and control foam in liquids. Its main components include polydimethylsiloxane (silicone oil), silicone emulsions, and silicone resins. These ingredients form highly effective defoamers through emulsification. It is also known as silicone oil antifoam.
Our Silicone Defoamer Formulation:
▪️Main Ingredients: Silicone polymers, solvents, and emulsifiers
▪️Other Ingredients: Stabilizers, pH adjusters
Appearance: White or light yellow liquid
Properties: Excellent chemical and physical stability, maintaining consistent performance under various environmental conditions.

Usage Instructions
The silicone defoaming agent can be used directly or diluted before application. For long-term storage of diluted products, please consult our company for the proper method.
For on-site use, Yuanwang recommends adding the silicone defoaming agent in areas where it disperses easily. For example:
In the papermaking pulping process, it is recommended to add it to the black liquor at places like the vacuum pulper inspection port, spray pipes, and water legs.
Yuanwang will provide reasonable suggestions based on your specific application!

The process uses a closed, high-efficiency stirring reactor. Raw materials are added to the reactor in sequence, and after being evenly mixed, the mixture is heated to a specific temperature for reaction.
During the reaction, additives such as promoters and stabilizers are introduced to control the reaction rate and product quality by adjusting time and temperature. After the reaction is complete, the product undergoes steps such as distillation, washing, filtration, and packaging to refine and purify the final product.
When stored between 5 and 40’0 (41-104’F ) in the original unopened containers, the product is usable 9 months from the date of manufacture.
