PMMA Particle Aggregates
I have been having an issue with a base that has been make several times.
Once I add PMMA at 0.5% and circulate my batch I cool.
At final check I have hard sharp particles.
Upon checking under the microscope they appear to be PMMA aggregates.
Our particle size is 0.7um and I’m getting aggregates about 10 mm in size.
Anyone have experience with this or know how to stop it? I’m mostly processing not formulation.
