Description

Tallow/Phthalic/Adipic/Neopentyl Glycol/Trimethylolpropane is a specialized, high-performance polyester polyol resin intermediate. This compound is engineered to deliver a unique balance of flexibility, hydrolytic stability, and reactivity, making it a critical raw material for advanced polymer formulations. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance. The CAS number for this substance is 68213-46-7.

Application

This versatile polyol resin is a key building block in the synthesis of high-value polymers. Its primary applications include:

• High-Performance Polyurethane Coatings: Used to formulate coatings with excellent weatherability, chemical resistance, and flexibility for automotive, industrial, and marine applications.
• Elastomers and Sealants: Imparts superior mechanical properties, low-temperature flexibility, and durability in polyurethane elastomers and construction sealants.
• Adhesives: Serves as a backbone resin for polyurethane adhesives requiring strong bonding and resistance to moisture and environmental stress.
• Specialty Plasticizers and Modifiers: Acts as a polymeric plasticizer or modifier to improve the toughness and processing of other polymer systems like PVC.
• Resins for Composites: Utilized in the production of unsaturated polyester resins or other composite matrices where a specific balance of rigidity and impact strength is needed.

Quality Control

Our production of this polyester polyol adheres to strict quality management protocols. Each batch is characterized by key parameters including hydroxyl value, acid value, viscosity, and color to ensure consistency and performance for your specific application. Certificates of Analysis (COA) documenting these specifications are provided with every shipment.

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 container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
