Properties of lubricant:
Is strongly locked into HDPE
It has same physical/mechanical properties as HDPE except low Coefficient of Friction value which is less than 0.06
Is evenly distributed around the bore and along the length of duct.
Does not react with water, hence it is possible to clean the duct by water stream in case of any obstruction/accident.
Same frictional properties during life of the duct.
