Steel Rotolining with micropellets (0,5mm) instead of powders (0,1-0,5mm)

Steel Rotolining with micropellets (0,5mm) instead of powders (0,1-0,5mm)

(OP)
Hello all,
Usually Steel Rotolining is carried our by means of PE powders. In most cases companies buy
PE powders for rotomoulding i.e. Icorene 1869 powder from LyondellBasell (Ico), supposed to be a LLDPE with additives (Maleic acid anyhidrid? SIlicone?) to enhance compatibility to steel.
However I have learnt that it is also possible to use micropellets of Polyethylene instead of powders.
The advantage seem to be the narrow particle size distribution and the fast dryflow of 12 seconds (powder 30 seconds).
When a certain temperature on the steel part is reached then all particles will melt quickly and at once.
In comparison to this, standard PE Powders with small and larger particle sizes will need more time to melt.
Have someone here considered the use of micropellets too?

I found that PE is the standard material for steel rotolining, but would PP also works?
The advantage would be that PP is stable against fluid media at higher temperatures above 60°C.

Many thanks for your answers.
CC.
