Polybutylene Adipate Terephthalate (PBAT) is an aromatic-aliphatic co-polyester that has emerged as one of the world's most versatile and highly regarded fully biodegradable plastics. Synthesized through the polycondensation of Terephthalic Acid, Adipic Acid, and Butanediol (1,4-BDO), PBAT combines the desirable properties of conventional plastics with near-complete biological degradability. It exhibits excellent ductility, high elongation at break, good heat resistance, and high impact performance. Crucially, its superior film-forming ability makes it perfectly suited for various film and bag products, such as shopping bags, garbage bags, and agricultural films.

The PBAT market is characterized by:
- Regulatory-Driven Demand: The industry's growth is fundamentally propelled by global mandates and national "Plastic Restriction/Ban" policies aimed at curbing the massive environmental impact of difficult-to-recycle or non-degradable plastic waste.
- Superior Performance within Bioplastics: PBAT is recognized as having the best overall mechanical performance among mainstream biodegradable plastics, particularly in terms of toughness and heat stability, which differentiates it from brittle materials like pure PLA.
- Overcapacity and Price Pressure: Rapid and massive capacity expansion in China since 2020 has led to a condition of severe overcapacity and low operating rates, creating intense price competition and profitability challenges for producers.
- Diversification and Blending: PBAT is a key component in sophisticated biodegradable material blends, most commonly compounded with PLA (Polylactic Acid) to achieve the optimal balance of toughness, gloss, and price (e.g., in supermarket shopping bags).
Product Types and Synthesis Routes
The quality and applicability of PBAT are heavily influenced by its synthesis method, which affects properties like food contact suitability.- Esterification-Melt Polycondensation Process (One-Step Method):
- Features & Trends: Considered the more sophisticated route, this involves direct esterification followed by melt polycondensation under high vacuum. The product forms an amorphous co-polyester with random block lengths.
- Key Trend: This process is favored for products requiring high food and drug safety performance, as it avoids the introduction of potentially toxic additives. Its advantages include a short, efficient process flow, stable product quality, and the ability to recycle BDO internally, leading to lower consumption and environmental impact.
- Chain Extension Process:
- Features & Trends: This method first synthesizes lower molecular weight co-polyesters, and then uses a chain extender (like diisocyanate) to boost the molecular weight.
- Key Trend: While this process was initially used to solve polymerization difficulties, the introduction of diisocyanate chain extenders limits the material's bio-safety, restricting its use in food packaging and human-contact applications.
