Compatibilizer BT-585

Scope of application

GMA grafts:

.  Base material:

o    Polyesters: PLA (polylactic acid), PBAT (polybutylene

adipate/terephthalate), PBS (polybutylene succinate), PCL (polycaprolactone).

o    Blending system: PLA/PBAT, PLA/starch, PBAT/PHA, PLA/cellulose, etc.

.   Processing: melt extrusion (twin-screw pelletizing), blown film molding,

injection molding, 3D printing (wire modification). 

             .   End-use applications:

o    High toughness packaging: biodegradable shopping bags, express film.

o    Agricultural mulch film: enhanced weather resistance, extended service life (degradation cycle can be controlled).

o    Food containers: PLA/PBAT tableware (heat resistance↑, deformation resistance).

Functions and Purposes

.   Interfacial capacitation:

o    Reduce phase separation by reacting epoxy groups with terminal

hydroxyl group (-OH) and carboxyl group (-COOH) of PLA/PBAT to form covalent bonds.

.   Performance optimization:

o    Mechanical enhancement.

o    Flexibility adjustment.

.   Processing improvement:

o     Reduced melt viscosity and improved blown film uniformity. 

             .   Degradation regulation:

o    Retard initial hydrolysis through homogeneous phase structure to avoid localized brittle fracture.
