Silicone surfactant is polyether modified siloxane, mainly used in polyurethane foams: such as PU rigid foam, flexible foam, shoe materials and other fields. It provides foams with fine cell and stability.
Silicone surfactants are a unique type of surfactant characterized by polydimethylsiloxane as the hydrophobic backbone and one or more organic silicone polar groups attached in the middle or at the end. The presence of Si-O bonds in its structure provides greater hydrophobicity and stability compared to traditional carbon chain surfactants, which have CC and CO bonds. Additionally, its high molecular weight and multi-branched structure contribute to excellent low temperature performance and compatibility, making it a highly efficient surfactant.
Among the many applications of silicone surfactants are foam leveling agents for polyurethane foams, emulsifiers, personal care materials, paint leveling agents, defoaming agents, antistatic agents, plastic modifiers, wetting agents, fuel additives, fabric finishing agents, water-soluble lubricants, release agents, pesticide additives, agricultural auxiliaries, etc.
Characteristics of silicone surfactants
1. Has excellent surface tension reduction properties.
2. Excellent wetting properties.
3. Defoaming and foam stabilizing properties.
4. Toxicity is basically physiologically inert.
5. Good emulsification effect and good matching performance.
