  • History Of Plexiglass

    In 1927, a chemist from a German company heated the acrylate between two glass plates, and the acrylate polymerized to form a viscous rubber-like interlayer that could be used as a safety glass for breaking. When they polymerized methyl methacrylate in the same manner, a plexiglass plate having e...

  • Characteristics Of Acrylic Lens

    A. Low density: due to the gap between the molecular chains, the number of molecules per unit volume is small, which determines the advantages of the resin lens: low specific gravity and light texture, which is 1/3-1/2 of the glass lens; B. Moderate refractive index: ordinary CR-39 propylene diet...

  • Introduction To Acrylic Lens

    The resin lens is an organic material. The inside is a polymer chain structure, which is connected to form a three-dimensional network structure. The intermolecular structure is relatively relaxed, and there is a space between the molecular chains which can generate relative displacement. The lig...
