COMPATIBILIZER ADDITIVES FOR IMPROVING THE DELAMINATION RESISTANCE OF PET/PA-MXD6 MULTILAYER COINJECTION STRETCH BLOW MOLDED BOTTLES

摘要

The delamination resistance of multilayer PET/ PA-MXD6 coinjection stretch blow molded bottles was found to be significantly improved through the use of small amounts of specific dual-functional compatibilizer additives, blended into the nylon layer during the sequential coinjection molding step. Such modified multilayer PET bottles resist delamination even under stress-concentrated impact testing conditions.
