Abstract

Abstract: Morphology of the gas-assisted injection molded polycarbonate/polyethylene(PC/PE) blend was investigated employing scanning electronic microscope(SEM). Although the gas-assisted injection molded parts have the skin-core structure as the conventional injection molded parts do, the morphology evolution of PC phasein the gas-assisted injection molded(GAIM) part and the conventional injection molded(CIM)part showed completely different characteristics. The deformation and distribution of PC phaseGAIM parts are extremely sensitive to melt temperature. On the basis of morphological descrip tion, the effects of the molding temperature on the mechanism of the PC phase deformation and distribu- tion are also discussed.

Key words: polycarbonate, polyethylene, blend;gas-assisted injection molding, morphology, gas penetration
