TOPIC: PMMA brands, KOREA

Has anyone had PMMA in korea?
Do we have any Korean members who can research Korean PMMA brands?
I was reading Dr Casavantes study on the PMMA brands a few months ago but can't find the thread. I remember it cited Professor Lemperle as saying there is an ideal particle size for PMMA beads, and the study concludes Linneasafe is the closest to the ideal size but still a little off, which got me wondering if there are any better PMMA brands in Korea which we haven't heard of.
