• Thermal Resistance

PC has better heat resistance than PMMA. The glass transition temperature (Tg) of PC is approximately 120°C, while PMMA's Tg is around 105°C.

• Impact Resistance

PC's impact resistance is 30-50 times higher than PMMA. PC is a ductile material, whereas PMMA is brittle.

• Flame Retardancy

PC is a flame-retardant material meeting UL94-V2 standards (internationally recognized) and is self-extinguishing, while PMMA is not flame-retardant.

• Environmental Friendliness

PC is an environmentally friendly plastic, whereas PMMA struggles to meet certain environmental standards due to its physical properties, leading to restricted use in some international applications.

• Light Transmittance

PMMA exhibits superior light transmittance (92%-93%), making it the optimal choice among transparent materials for applications like optical waveguides and medical devices. PC has a lower transmittance of 86%-89%.

• Cost

The cost of polycarbonate (PC) is higher than that of polymethyl methacrylate (PMMA).
