Performance Comparison: PMMA vs PC

Performance Comparison: PMMA vs PC

• Physical Properties: PC offers superior toughness and impact resistance; PMMA behaves as a brittle material
• Thermal Performance: PC maintains higher heat resistance (Tg ≈ 120°C vs PMMA's 85°C)
• Surface Properties: PMMA provides better scratch resistance despite PC's overall wear resistance
• Flammability: PC achieves UL94 V-2 rating without additives
• Optical Clarity: PMMA demonstrates superior light transmission (92-93% vs PC's 86-89%)
• Weather Resistance: PMMA exhibits excellent inherent weatherability; PC requires UV stabilizers
• PC Applications: Glazing, automotive components, electronics, medical devices, protective equipment
• PMMA Applications: Automotive lighting, medical containers, optical diffusers, transparent consumer products
