Description

Polyoxyalkylenes, C4-6, Propoxylated is a specialized class of non-ionic surfactants and polyether polyols derived from propylene oxide and a C4-6 initiator. This product matters for its ability to act as a versatile intermediate and functional additive, offering tunable hydrophobicity and reactivity. It is primarily needed by manufacturers in the polyurethane, coatings, and lubricant industries for formulating flexible foams, sealants, and specialty fluids.

Application

• As a key polyol component in the production of flexible polyurethane foams and elastomers.
• As a surfactant and dispersing agent in coatings, inks, and adhesive formulations.
• As a lubricant base stock or additive for synthetic lubricants and hydraulic fluids.
• As a chemical intermediate for further ethoxylation or chemical modification.
• As a plasticizer and viscosity modifier in polymer and resin systems.
• In the formulation of demulsifiers and defoamers for industrial processes.

Quality Control

Our Polyoxyalkylenes, C4-6, Propoxylated is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including hydroxyl value, viscosity, water content, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting full specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
