Products Description

Biodegradable Polymer PBAT

What is PBAT

PBAT, chemically known as poly(adipic acid terephthalic acid butylene glycol), is a semi-crystalline aliphatic-aromatic copolyester. Presented as milky white or yellowish white odorless particles, it is synthesized through the direct condensation copolymerization of adipic acid, terephthalic acid, and butylene glycol. Boasting a melting point of 110–120°C and a density of 1.26g/cm³, PBAT offers exceptional physical properties:

Superior Toughness: Resists tearing and stretching, making it ideal for durable applications.
Wide Processing Window: Adaptable to various manufacturing techniques, including blow molding, extrusion, and spray coating.
Excellent Film-Forming Ability: Can be processed on standard plastic film equipment, reducing the need for specialized machinery.

The Environmental Edge of PBAT

What truly distinguishes PBAT is its full biodegradability. Under controlled conditions, such as industrial composting, seawater, or natural environments, microorganisms break down PBAT completely into carbon dioxide and water, leaving no harmful residues.

Products application

Through innovative modification, PBAT's versatility expands even further, catering to various industries.

Diverse Applications of Biodegradable Polymer PBAT

Packaging Industry

Bags & Films: From shopping bags to agricultural films, PBAT's flexibility and strength make it perfect for applications requiring both durability and eco-friendliness.
Food Packaging Containers & Trays: Safe for direct food contact, these solutions replace single-use plastic while maintaining heat resistance and structural integrity.

Foodservice & Disposables

Cold and Heat-Resistant Straws: Available in straight, curved, and artistic designs, these straws withstand temperatures from icy drinks to hot soups without compromising on sustainability.
Thin Wall Injection Molding Products: Lightweight yet robust lunch boxes, dental floss stick handles, cutlery (knives, forks, spoons), toothbrush handles, and combs-all designed for convenience and eco-conscious disposal.

3D Printing Wire

3D Printing Filament: PBAT's smooth extrusion and dimensional stability make it a popular choice for eco-friendly 3D printing.

Biodegradable plastic bags

Biodegradable mulch

Straws

Tableware

PBAT's appeal extends beyond its environmental benefits. For manufacturers, it offers:

Compatibility with Existing Equipment: No need for major machinery upgrades-PBAT can be processed on standard plastic film and molding equipment, ensuring cost-efficiency.
Customizable Performance: Modifications allow tailoring of properties like flexibility, heat resistance, and degradation rate to suit specific application requirements.
Market Differentiation: By adopting PBAT, brands can align with consumer demand for sustainable products, enhancing brand loyalty and meeting ESG (Environmental, Social, Governance) objectives.
