Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Ethers With Polyethylene-Polypropylene Glycol Mono-Me Ether is a specialized organomodified silicone fluid, engineered by combining polydimethylsiloxane (PDMS) backbones with hydrophilic polyether segments. This unique hybrid structure provides exceptional surfactant properties, enabling it to act as a powerful compatibilizer and performance modifier in complex formulations. It is a critical material for formulators in the personal care, coatings, and polyurethane foam industries seeking to balance silicone's slip and release characteristics with enhanced water solubility and foam stabilization.

Application

• Personal Care & Cosmetics: Acts as a key surfactant and emulsifier in high-performance shampoos, conditioners, and skin care products, providing improved wet combing, softness, and stable emulsions.
• Polyurethane Foam Production: Serves as a crucial cell opener and stabilizer in flexible slabstock and molded foam formulations, ensuring uniform cell structure and preventing shrinkage.
• Industrial & Institutional (I&I) Cleaners: Used as a wetting agent and defoamer component in hard surface cleaners and automotive care products for superior surface spreading and cleaning efficiency.
• Coatings & Inks: Functions as a flow and leveling additive, reducing surface defects (e.g., craters, orange peel) and improving substrate wetting in water-based and solvent-based systems.
• Textile & Fiber Treatment: Imparts softness, lubricity, and antistatic properties to synthetic and natural fibers during processing and finishing.
• Agricultural Adjuvants: Enhances the spreading, adhesion, and penetration of pesticides and herbicides on plant surfaces, improving efficacy.
• Adhesives & Sealants: Used as a processing aid and internal release agent to improve flow and prevent adhesion to mixing equipment.

Quality Control

Our organomodified silicone polyethers are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as viscosity, hydroxyl value, ethylene oxide/propylene oxide (EO/PO) ratio, and silicone content. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee compliance with your formulation requirements and support your own quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
