A transformative bridge between high-strength synthetic polymers and eco-conscious biopolymers, meticulously designed for structural resilience and rapid biodegradability.
Molecular Precision & Synthesis
Engineered through precise polycondensation, the PBAT backbone consists of two critical repeating units: Butylene Adipate (BA) and Butylene Terephthalate (BT).
The "Golden Ratio" Optimization
Maintaining a BT mole fraction between 40% and 60% ensures the material is robust enough for film blowing while remaining susceptible to microbial breakdown.
Aromatic BT Units
Provides Π-Π stacking necessary for crystallinity, dictating the material’s melting point (Tm) and mechanical stiffness.
Superior Mechanical Versatility
The "biodegradable twin" of LDPE with superior environmental credentials.
Elasticity & Toughness
Elongation at break between 500% and 800%. Ideal for flexible packaging and agricultural mulch where ductility is paramount.
Thermal Resilience
With a Tg of -30°C, PBAT remains flexible in cold-chain environments, avoiding cracking issues common in other bio-based materials.
Controlled Processing
Managing the polydispersity index ensures exceptional melt strength during extrusion, reducing material waste in high-speed lines.
Ready for a Material Transition?
Whether you are looking to enhance puncture resistance or seeking a stable base for starch-blends, our experts are here to navigate the chemistry for you.
Systematic Biodegradation & Stability
Predictable end-of-life cycles are the foundation of true sustainability.
Surface Erosion
Extracellular enzymes (lipases/esterases) initiate the breakdown at industrial composting conditions (58 ± 2°C).
Chain Fragmentation
Molecular chains are cleaved into smaller oligomers.
Full Mineralization
Final conversion into biomass, H₂O, and CO₂ with zero toxic residues, meeting EN 13432 / ASTM D6400.
