What' The Difference Between PMMA And PC?

There are 6 points of difference between PMMA and PC:

1. Physical properties
The toughness and impact strength of PC are better than PMMA. PMMA is a brittle material.

2. Temperature resistance
The temperature resistance of PC is better than that of PMMA. The TG of PC is 120°, and that of PMMA is only 85°.
3. Abrasion resistance
The wear resistance of PC is better than PMMA, but the surface wear resistance is much lower than that of PMMA, so adding PMMA to scratch-resistant high-gloss ABS material
gold modification.

4. Fire resistance
The fire resistance of PC is better than that of PMMA, that is, it has good flame retardancy. Ordinary PCs can reach fire rating V2.

5. Translucency
The light transmittance of PMMA is better than that of PC, and the light transmittance of PMMA reaches 92% to 93%, which is the best among transparent materials, so it is often used in multi-light guides and medical equipment.
The PC is only 86-89%.

6. Weather resistance
PMMA has very good weather resistance and is often used as outdoor products. When PC is used as outdoor products, UV agents and antioxidants should be added.
