Plexiglas®

Description

[Plexiglas] A registered trademark for a transparent, thermoplastic Acrylic sheet. Plexiglas® is composed of Polymethyl methacrylate. It was invented by Otto Rohm and Walter Bauer of Rohm and Haas in Darmstadt Germany. They coined the name Plexiglass because it looked like Glass but could be heated and formed into many shapes. Rohm and Haas patented the product in 1933 and by 1936 was marketing the acrylic sheets under the name of Plexiglas® as a nonbreakable substitute for glass. The clear, lightweight material can be scratched easily and is marred by solvents. It also accumulates a static charge that attracts particles. Plexiglas® is used for signs, lens, containers, windows, skylights, windshields, protective glazing, chalkboards and furniture. Some types of Plexiglas® are:

- Plexiglas® G UF-4: transmits less than 10% UV and does not have a yellow cast. Transmission starting at 385nm. Overall better visible light transmission; sheet with slightly better edge color

- Plexiglas® G UF-3: transmits less than 2% UV and has a slight yellow cast.Transmission starting at 395nm.


In the United States, Plexiglas® is also sold under the trademark Acrylite®. Some forms of Acrylite® are:

- Acrylite® OP3 MR1: UV filtering mar resistant. 92% light transmission. Transparent. Mar resistant coating (one-sided).

- Acrylite® OP3 P99: UV filtering. 91.9% light transmission. Non-glare surface (one-sided). Soft matte finish.

- Acrylite® OP3: UV filtering. 92% light transmission. Transparent. High-gloss surface.
