Difference between PMMA and PC materials

The difference between PMMA and PC materials and their respective advantages
1. Physical properties
The toughness and impact strength of PC are better than that of PMMA. PMMA is a brittle material.
2. Temperature resistance
The temperature resistance of PC is better than PMMA. The TG of PC is 120°, and the PMMA is only 85°.
3. Wear resistance
The wear resistance of PC is better than that of PMMA, but the surface wear resistance is much lower than that of PMMA, so PMMA is added to the bruise-resistant high-gloss ABS material for modification.
4. Fire resistance
The fire resistance of PC is better than that of PMMA, that is, it has good flame retardancy. A common PC can reach the fire protection level V2.
5. Light transmission
PMMA's light transmission performance is better than PC, PMMA's light transmission rate of 92% to 93% is the best among transparent materials, so multi-light guide and medical equipment are often used, while PC is only 86-89%.
6. Weather resistance
PMMA weather resistance is very good, commonly used as outdoor products, PC used as outdoor products to add ultraviolet agents and antioxidants.
