The effect of morphology and microstructural interfaces on the properties of high density polyethylene blow moulded containers

Through the years blow moulding has found applications in the production of containers ranging in size from bottles to barrels. The phenomenon of cooling a barrel is different in detail to cooling a bottle, mostly due to the differences in thickness of the two. A common belief is that for faster cooling, the mould should be chilled and internal coolants like liquid nitrogen, liquid carbon dioxide or water spray used. In the present study, the effects of cooling conditions and various other processing parameters on performance have been investigated. [Continues.]
