Polypropylene
#1
Have been running Polypropylene without any issues. In the last few weeks we have switched from Polypropylene to Polypropylene with a clarifier. The clarifier is Mallid 3899. This has a tendency to leach out of the plastic. It tends to be very gassy and regular cleaning methods are not working. What is the best method for cleaning in this application?

Thx in advance.

Additives can create problems as you have seen. We have had the best success with Acetone in an explosion proof ultrasonic cleaner. However there have been occasions when this has not worked completely. In those cases we tell the customer or if we are doing the cleaning for the customer we call the resin supplier and ask what solvent will best clean the residue of the resin and the additive. Also make sure you blow back thru the Porcerax II in the opposite direction to the venting air flow to insure that residue inside the Porcerax II is forced out.

Thanks Mr Buckley. That sounds like the best way to do it.
