7. What factors should I consider when choosing between different types of white plastic sheets (e.g., acrylic, polycarbonate, PVC)?

Evaluate the specific application requirements: impact resistance favors polycarbonate, optical clarity favors acrylic, while chemical resistance suits PVC. Consider environmental exposure—UV stability and weather resistance are crucial for outdoor use. Cost is a key factor; acrylic is generally more affordable than polycarbonate, but the latter offers superior durability. Mechanical properties, fire safety standards, and recyclability also influence choice. Align your selection with industry standards and local regulations. Consulting with suppliers about these factors helps ensure the material aligns with your technical, budgetary, and sustainability goals.
