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