Epoxy chain extender DB-G

Chemical Name: Epoxy chain extender DB-G

Main Ingredient: 2-Propenoic acid, 2-methyl-, oxiranylmethyl ester, methyl methacrylate, polymer with ethenyl benzene

Specification 

Appearance: White powder or granular

Purity(%):≥99.5

Epoxy equivalent (g/mol):300-330

Volatile : < 2%

Applications:

DB-G blended polymer with epoxy functional groups and ring-containing group ring-opening accelerator. It mainly applied in polyester and biodegradable resin, improve resin molecular chains, reduces melt index, and improves processing performance. DB-G is usually extruded in combination with resins by use single- screw, twin-screw extruders. In biodegradable plastics such as PET, PBAT, PLA, and PBS, the specific dosage can be determined according to the actual resin indicators and product performance requirements.

The conventional addition amount is: 0.2-1.0%.

Product advantages:

Small addition amount, remarkable performance.

Good heat resistance and stable processing process.

The epoxy group has good activity and high ring-opening rate.

Improve compatibility and mechanical properties.

Package and Storage

1. 25KG bag

2. Store the product in a cool, dry, well-ventilated area away from incompatible materials.
