Abstract
The present relates to the heat shrinkable thermoplastic materials which are used as roll covers. The heat shrinkable materials used for the roll covers include only ultra high melt viscosity polymers, having a melt viscosity too high for conventional melt processing, such as TFM and UHMWPE, rather than the conventional FEP or PFA.
