Grafting modification of polypropylene (PP) and polyethylene (PE) involves introducing chemical functional groups or polymer chains onto the PP/PE polymer backbone. This modification can enhance the properties and performance of these polymers for various applications.

Twin-extruders act as continuous flow reactors for polymers playing an increasingly important role in producing high performance thermoplastics. 

Nanjing jieya design and manufactures complete production line for graft compounding with 20 years industry experience.Our twin screw extrusion lines are customized individually to the application: from material transfer and feeding to reaction compounding, devolatilization, pelletizing, conveying and packaging.
