Description

Fatty Acids, C16-18 And C18-Hydroxy, Polymers With Adipic Acid, Decanoic Acid, Isostearic Acid, Octanoic Acid, Pentaerythritol And Stearic Acid CAS NO 130353-58-1 is a high-performance, synthetic polyester polyol derived from a complex mixture of fatty acids and multifunctional alcohols. This specialized polymer is engineered to deliver unique rheological and surface-active properties, making it a critical component in advanced material formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in lubricant and plasticizer production, where its tailored structure enhances product durability and performance.

Application

• Coatings & Resins: Acts as a reactive polyol in alkyd resins and polyurethane coatings, improving flexibility, adhesion, and chemical resistance.
• Adhesives & Sealants: Used as a building block in polyurethane and polyester-based adhesives and sealants to modify viscosity and enhance bonding strength.
• Lubricants & Greases: Serves as a synthetic ester base fluid or thickener, offering excellent thermal stability and lubricity.
• Plasticizers: Functions as a polymeric plasticizer for PVC and other polymers, providing low volatility and improved permanence.
• Elastomers: Incorporated into polyurethane elastomers to tailor hardness, resilience, and hydrolytic stability.
• Inks: Used in specialty ink formulations to adjust rheology and improve substrate wetting.
• Personal Care: Employed as an emollient and viscosity modifier in high-end cosmetic and skincare products.
• Industrial Additives: Functions as a dispersant, compatibilizer, or processing aid in various polymer composites and masterbatches.

Quality Control

Our production of this advanced polyester polyol adheres to strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistency in critical parameters such as hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are provided and can be tailored to meet specific customer or regulatory requirements, including those relevant to industrial and specialty chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and organic solvents. Due to its polymeric and hygroscopic nature, exposure to excessive moisture and high temperatures should be avoided to prevent hydrolysis or changes in viscosity.
