The high rigidity of the molecular chains and their exceptionally large size (very high molecular weight) result in an extremely high melt viscosity for polytetrafluoroethylene, making it difficult to flow.
The high rigidity of the molecular chains and their abnormally large size (very high molecular weight). It makes the melt viscosity of polytetrafluoroethylene extremely high, making it difficult to flow.
