Bioriented PVC items show strongly improved mechanical properties versus standard PVC.
It is known that biorientation efficiency is related with PVC Molecular weight since very low molecular weight resins are not very suitable for biorientation.
Generally bioriented pipe processors recommend Kw > 64.
The target of this study is to quantify the relationship between the Kw (molecular weight) of the PVC and the properties obtained after biorientation 2. Preparation of the PVC plate samples PVC Plates were realised by roll milling and compression moulding.
