Polyvinylidene Fluoride for Resistant and Long Life Pipes

 

Materials and Their Characteristics # 1985 York

The characteristics of PVDF are derived from its essential features. It is a semi-crystalline thermoplastic fluoropolymer

This leads to the properties
High burst resistance
Long-term reliability - virtually no ageing
Easy processability
Chemical resistance

No scaling 0 Service temperature up to 140 C
Examination of the thermomechanical properties of PVDF essentially using long-term hoop data now extending over ten years and up to 1500C shows interesting curves.
There is no fall-off in properties with time, a unique feature in thermoplastic pipes. All the curves are within the ductile region.

The high crystal energy of PVDF combined with the strength of the C-F bond make it probably the strongest of the fluoropolpers. Chemical resistance is outstanding, as one would expect of a fluoropolper, so the material has a useful combination of properties to offer in the field of piping. A brief summary of the...
