Did you try with only LDPE with the same temperature profile ?
Yes I did only LDPE to clean but ı cannot get rid of powder from screw. I have to clean surface of screw from powder
I do not know if I understood well the technical problem, hence i apologize if my answer is inappropriate.
If this powder is polar you can use a functionalized polyolefin or EVA to compatibilize PE and the powder. Probably the powder can get stick to LDPE and be carried out from screws.
If you have some sligthly plasticized PVC, use it and apply a 150°C flat temperature, results usually are great...
Mrs.Maria-Beatrice Coltelli I have already used LDPE and powder together but powder is stick to screws. When I use only LPDE to clean sticked material on screw, it didn't work. Powder is remain on my screw surface. Mr.Victor I will try suggestion thank you.
Hi Bekir,
I am not sure what antimicrobial powder you do have, but I will do following.
Hope this helps, good luck,
Mayur.
Mr Mayur,
I will try your option A it is very useful for me thanks a lot your suggestion.
I would use a low MI HDPE. Also, there were rubber modified film grade PE resins which have been known to scour the barrel wall and the extruder flights pretty well.
I hope you can clean it already.
My experience was in a single screw extruder. I have to remove powder residues heating and then remove the screw in hot to clean it.
