Chain Extender SADR-4370

BASF JONCRYL ADR-4370 equivalent;it’s an efficient additive to upgrade recycled plastics with better properties which is close or equal to new plastics;it’s a polymeric chain extender with high epoxy functionality for condensation thermoplastics to increase the molecular weight、melting strength of resins which can improve the precessing and mechanical properties of different plastics.M.W.:6500~7000,Epoxy equivalent weight(g/mol):270~3000;Tg(℃)：61

Specifications:

Applications:

• Chain extender SADR-4370 a polymeric chain extender with high epoxy functionality.it can  react with the terminal hydroxyl group,terminal carboxyl group and terminal amino group of PLA、PPC、PBS、PHA、PBT、PET、PA、PC and biodegradable polyesters plastics at the normal operation temperature.re-coupling of the broken chains by heating or hydrolyzation can be reformed by this kind of reaction.this results in higher molecular weight and melting strength of the products which make the resins with better processing and mechanical properties;

• Chain extender SADR-4370 is a versatile chain extender/compatibilizer with high epoxy functionality.this allows for rapid reaction with condensation thermoplastics,resulting in higher molecular weight;

• Chain extender SADR-4370 is a polymeric coupling agent that reacts with degraded polymers to restore the original molecular weight as well as Intrinsic viscosity and melt viscosity;

• Recycled plastics can be upgraded to be with good quality by chain extender SADR-4370;
  Chain extender SADR-4370 can be used during processing to increase the melt strength of polyesters or polyamide(nylon).this is useful in extrusion applications;

• Chain extender SADR-4370 is not approved for food contact in PET

Recommended Dosage:

• PLA、PPC、PBS、PHA and biodegradable polyesters:0.2%~1.5%.

• Recycled Condensation polymers such as PET、PBT、PC、PA: 0.2%~2.0%

• exact dosage depends on the active group in the resin and the characteristic request of the finished goods.please contact us for detailed guideline

Advantages:
Increase IV and MW of polyesters;
