Categories:	Polymer; Film; Thermoplastic; Acrylic (PMMA); Acrylic, General Purpose, Molded
Material Notes:	ROHAGLAS® Film 99524 acrylic film, based upon polymethyl methacrylate and acrylic elastomers, offers crystal-clear optical properties with two glossy (Class A) surfaces. Its excellent abrasion resistance, combined with long-term outdoor weatherability offers outstanding performance as a decor carrier and as a substrate surface protector. ROHAGLAS 99524 film has superior processability in die-cutting and all forming processes. In addition, it presents good resistance towards weak acids and alkalis as well as non-polar solvents.
