What Is the Difference Between PMMA and PC?

PMMA and PC are transparent thermoplastics, but they are selected for different performance priorities. PMMA provides excellent optical clarity, surface hardness, and outdoor weather resistance, while PC offers much higher impact strength, better heat resistance, and greater resistance to sudden breakage.

Does Acetone Melt Plastic?

Acetone can melt, soften, swell, crack, or damage some plastics, but it does not affect every plastic in the same way. The result depends on the plastic type, exposure time, acetone concentration, temperature, surface stress, and whether the part is coated, printed, or blended with additives.
