Description

Poly(1,3-Propylene Succinate) is a biodegradable aliphatic polyester derived from succinic acid and 1,3-propanediol. This polymer is valued for its excellent biodegradability, biocompatibility, and versatile material properties, making it a key component in sustainable material solutions. It is primarily sought by manufacturers in the biodegradable plastics, biomedical engineering, and eco-friendly packaging industries.

Application

• Biodegradable Plastics & Films: Used in the production of compostable bags, agricultural mulch films, and disposable packaging materials.
• Biomedical Devices: Serves as a matrix for controlled drug delivery systems, surgical sutures, and tissue engineering scaffolds due to its biocompatibility.
• Eco-friendly Coatings & Adhesives: Formulated into water-based or solvent-based coatings and adhesives with reduced environmental impact.
• 3D Printing Filaments: Utilized as a sustainable material for fused deposition modeling (FDM) in additive manufacturing.
• Fiber & Nonwoven Production: Processed into biodegradable fibers for textiles, hygiene products, and filtration media.
• Polymer Blends & Modifiers: Acts as a biodegradable additive or blending component to enhance the environmental profile of other polymers.

Quality Control

Our Poly(1,3-Propylene Succinate) is manufactured under a strict quality management system. Each batch undergoes comprehensive analysis to ensure consistent molecular weight, purity, and material properties. Certificates of Analysis (COA) detailing key parameters such as inherent viscosity, melting point, acid value, and residual monomer content are provided and available upon request.

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