*PVCu has a softening point in excess of 70ºC, and PVCu soil stacks can cope with short intermittent discharges with temperatures up to 90ºC. Modified unplasticised polyvinyl chloride, MuPVC, has a softening point above 90ºC so, in addition to the normal properties of PVCu, it can also cope with higher temperature discharges over prolonged periods.
The higher softening point of polypropylene, above 140ºC, means it can cope with high temperature discharges, such as boiling water, and it is the most appropriate material for the manufacture of traps.

*BS EN 1566-1: covers PVC-C items and replaces BS 5255 for MUPVC pipe and thin- walled fittings.
*BS EN 1566-1:2000 Plastics piping systems for soil and waste discharge (low and high temperature) within the building structure. Chlorinated poly(vinyl chloride) (PVC-C). Specification for pipes, fittings and the system
These should help you better understand the differences between them...good luck.
