Acrylic (ACRYLIC), commonly known as special treatment plexiglass. Acrylic research and development, now has more than a hundred years of history. 1872 acrylic polymeric beginning to be discovered; 1880 methacrylate polymerizable become known; 1901 propylene polymer acid lipid synthesis study was completed; in 1927 the use of the above synthetic method to try industrialized manufacturing; methacrylic acid ester 1937 manufacturers successfully developed, thereby entering the scale manufacture. Weather PMMA has excellent resistance to atmospheric aging acrylic fish tank, which sample after 4 years of natural aging test acrylic, weight change, tensile strength, light transmission rate decreased slightly acrylic cosmetic bracket, color slightly yellowing acrylic frames, anti-crazing decreased obviously, impact strength also increased slightly, almost no change in other physical properties. Combustion of poly (methyl methacrylate) is easy to burn, limiting oxygen index is only 17.3. Acrylic photo frame with plexiglass exhibition (certified), acrylic by the Dongguan City Shek Pai with exhibition plexiglass products factory provided. Dongguan City Shek Pai with exhibition plexiglass products plant (zskbfw.1688.com/)(www.tangzhan88.com) is an industry leader in Dongguan, Guangdong, picture frames, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs. At the same exhibition plexiglass leadership with the staff warmly welcome all inquiries negotiations to create the same exhibition plexiglass better future.
