Chemical name :
MAH grafted hybrid elastomerAppearance :
White granuleMelting Point :
120±10℃Recommended Dosage :
1-3phrProcessing Temperature :
160-300℃Compatibilizer BT-468
Applications
BT-468 maleic anhydride graft is mainly used to improve the compatibility of the biodegradable plastic blend system and is suitable for the following
scenarios:
. Resin：
o Polyesters: PLA (polylactic acid), PBAT (polybutylene
terephthalate/butylene terephthalate), PBS (polybutylene terephthalate), PHA (polyhydroxyalkanoates).
o Blending systems: PLA/PBAT, PLA/starch, PBAT/PBS, PLA/PHA, etc.
. Processing：melt blending (extrusion, injection molding), solution casting,film blowing molding.
. Products：
o Packaging materials: food packaging film, biodegradable plastic bags (to improve flexibility and tear resistance).
o Agriculture: mulch film, seedling tray (improve weather resistance and mechanical strength).
o Disposable items: tableware, straws (enhance heat resistance and impact resistance).
o Biomedical materials: sutures, drug release carriers (optimize degradation rate and mechanical properties).
Function and purpose
. Enhance interface compatibility:
o Reduce the phase separation of the blending system.
o Improve the bonding of the interface.
. Optimization of mechanical properties:
o Improve impact toughness.
o Balance rigidity and flexibility.
. Regulation of degradation behavior:
o The degradation rate is slowed or accelerated by uniform phase structure.
. Processing performance improvement:
o Reduce melt viscosity and improve molding efficiency.

局限性 |
|
Maleic anhydride graft |
High reactivity and strong interface binding |
The grafting rate should be controlled accurately, and excess is easy to crosslink |
|
Epoxy compatibilizer |
Good water resistance, suitable for humid environment |
The cost is high and may delay degradation |
|
ionic liquid |
High efficiency dispersion, improve melt flow |
Poor thermal stability and easy migration |
|
Nanoparticles (e.g., SiO₂) |
At the same time, the mechanical and barrier properties are enhanced |
Difficult to disperse, easy to agglomerate |
|
Polyurethane compatible agent |
Super flexibility (elongation at break> 400%) |
The degradation rate is slow and toxic |
|
Natural Compatibilizer (such as chitosan) |
Fully bio-based and non- toxic |
Low efficiency (addition amount> 10%) |
