Description

Poly(1,4-Butylene Adipate) is a biodegradable aliphatic polyester derived from 1,4-butanediol and adipic acid. This polymer is valued for its excellent flexibility, biodegradability, and compatibility with other polymers, making it a crucial component in the development of sustainable materials. It is primarily sought by manufacturers in the plastics, packaging, and biomedical industries for applications requiring controlled degradation and enhanced material properties.

Application

• As a primary component or modifier in the production of biodegradable plastics and compostable packaging.
• Used as a polymeric plasticizer to improve the flexibility and processability of rigid polymers like PLA (Polylactic Acid).
• In the formulation of environmentally friendly adhesives and coatings.
• As a raw material for synthesizing polyurethane elastomers with tailored soft segment properties.
• In biomedical applications for controlled drug delivery systems and biodegradable medical devices.
• As an additive in mulch films and agricultural products designed for in-situ biodegradation.

Quality Control

Our Poly(1,4-Butylene Adipate) is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent molecular weight, purity, and performance characteristics. Certificates of Analysis (COA) detailing key parameters such as intrinsic viscosity, acid value, and thermal properties are available upon request to support your quality assurance protocols.

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 container tightly sealed to prevent moisture absorption, which can affect polymer properties.
