Product Description
BX ADR 3700 is a polymeric epoxy functional chain extender. The epoxy functional group in its structure can achieve chain extension of the polymer by reacting with the terminal hydroxyl group, carboxyl group and amino group in the condensation polymerization resin, thereby improving the performance of the condensation polymerization resin. Characteristic viscosity, mechanical properties and the purpose of inhibiting polymer hydrolysis.
Applications
Chain extender BX ADR 3700 modification:
70% PBAT+30% PLA mixture, 195℃
Dosage
① The recommended dosage in bio-based and biodegradable plastics such as PLA, PPC, PBS, PHA, etc. is 0.2-1.5 wt%;
②The recommended dosage in polycondensation recycled plastics such as PET, PBT, PC, and PA is 0.2-2.0 wt%.
③ The specific dosage depends on the number of active functional groups in the resin and product performance requirements.
