Description

Poly(1 4-Butylene Glutarate) Hydroxy is a biodegradable aliphatic polyester polyol derived from glutaric acid and 1,4-butanediol. This versatile polymer intermediate is valued for its ability to impart flexibility, biodegradability, and specific reactive functionality to final polymer formulations. It is primarily sought by manufacturers in the polyurethane, adhesive, coating, and biomedical material industries seeking to develop sustainable and performance-driven products.

Application

• Polyurethane Elastomers & Foams: As a soft segment polyol to create flexible, biodegradable PU materials for coatings, adhesives, sealants, and elastomers (CASE).
• Biodegradable Polymers: As a key monomer or prepolymer in the synthesis of fully biodegradable polyesters for packaging and agricultural films.
• Adhesives & Sealants: To enhance the flexibility, toughness, and environmental profile of hot-melt and reactive adhesive systems.
• Coating Resins: Used in the formulation of high-performance, flexible, and weatherable coatings for various substrates.
• Biomedical Engineering: As a biocompatible building block for creating resorbable scaffolds, drug delivery matrices, and other implantable devices.
• Plasticizers & Modifiers: To improve the processability and impact resistance of rigid polymers while maintaining biodegradability.

Quality Control

Every batch of Poly(1 4-Butylene Glutarate) Hydroxy is manufactured under a strict quality management system. We provide comprehensive quality assurance through in-process and final release testing, including analysis of hydroxyl value, acid value, molecular weight distribution, and moisture content. A Certificate of Analysis (COA) detailing all specifications is available with each shipment to ensure traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original container tightly sealed when not in use to prevent moisture absorption, which can affect reactivity.
