Covestro Makrolon® LD sheet Polycarbonate
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	Light diffusing Makrolon® LD sheet is a polycarbonate product designed with an advanced light diffusion technology that provides excellent light uniformity without sacrificing light transmission. The proprietary diffuser technology eliminates visible hot spots from pinpoint LED lights in typical flat and formed sign applications. LD is available in a range of standard sign colors and can be custom matched to any color. Makrolon LD is easy to form, fabricate, and decorate, and has excellent impact strength and dimensional stability. The product’s UV resistance technology assures long lasting outdoor weathering performance. Makrolon LD is offered with a ten (10) year limited product warranty against breakage. Applications: Flat and formed sign faces, channel Information provided by Covestro
