Satin-finished Polymethyl Methacrylate (PMMA) is a high-quality plastic material, characterized by a matte finish that diffuses light evenly. This material is ideal for applications requiring a sophisticated aesthetic and glare-free light distribution. The satin PMMA selected by PTH is an excellent choice for applications demanding uniform light distribution, refined aesthetics, and good weather resistance. This versatile and lightweight material is perfect for tubes and profiles used in industries such as lighting, interior design, and signage, ensuring exceptional performance and long-lasting durability.
