mixing PP/carbon
mixing PP/carbon
(OP)
I need to mixing PP with carbon, but composition of PP < 10 %wt. will be prepared with different percentages PP–carbon 6:94 and 8:92. whether it can be formed into a rectangular plate? Please tell me, how about the procedure?
do I need a solvent for PP? does anybody know a good solvent for PP?
thanks

RE: mixing PP/carbon
What do you mean by carbon. It comes in many forms, however I doubt that polypropylene can we it out at that quantity if mixed with molten polypropylene.

RE: mixing PP/carbon
thanks for your answer
I will mixing polypropylene + carbon black powder, but composition of PP < 10 %wt. will be prepared with different percentages PP–carbon black powder 6:94 and 8:92. whether it can be formed into a rectangular plate?
Please tell me, how about the procedure and method?
RE: mixing PP/carbon
I think for carbon black it is probably difficult to get more than 40% into PP. Maybe less.
The method is usually feeding both materials into a twin screw extruderthat melts the PP and mixes the carbon powder into the melted PP

Thanks! A compliment indeed coming from you. My mind works in simple terms like that. Easier to relate to than equations and obscure theories.

In some work I did we avoided chlorinated solvents and used a MARSX Microwave oven accelerated reaction system for extraction from CEM where the solvent was 25 ml of a 30% n-Hexane, 70% Ethyl-acetate.
I am not 100% sure that dissolved the PP, it did definitely swell it.
