Injection-molded PMMA grades differ in properties: General-purpose PMMA offers optical clarity but limited impact resistance. High-impact PMMA adds durability. Optical-grade PMMA ensures superior clarity. High-performance PMMA combines strength and clarity, and UV-resistant PMMA offers protection against UV degradation. These differences suit various applications.
Neway employs various grades of injection molded PMMA, including:
Plexiglas® (General-Purpose PMMA)
Altuglas® (High-Impact PMMA)
Optix® (Optical-Quality PMMA)
Lucite® (High-Performance PMMA)
Acrylite® (UV-Resistant PMMA)
Comparing injection molded PMMA grades provides the advantage of tailoring material properties to specific needs. Whether it's optical clarity, impact resistance, or UV protection, choosing the correct grade ensures optimal performance and durability for plastic injection molding parts.
