NUDEC® PMMA Polymethylmethacrylate Sheet
Categories:	Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, Optical Sheet
Material Notes:	These plastic sheets show excellent stability to outside weather conditions, including UV radiation. Even after years of exposure to sunlight, the sheets do not show any substantial variations in their optical properties. Their high optical quality makes them suitable for certain filters (TV and computer), for glazing and even suitable for manufacturing mirror production. NUDEC® PMMA plastic sheets are manufactured in several thicknesses and can be ordered in other tones, such as opal, in various patterns, which includes the so-called technical patterns, which are highly recommended for lighting applications. Sheet properties: Excellent transparency, with a fixed 92% light transmission. Bright and colorless. High rigidity. Resistant to outside weather. Elevated hardness. They can be molded. Intermediate mechanical strength. The surface is suitable for buffing. Information provided by NUDEC.
