Trinseo Plexiglas® DR® UVA20 Acrylic  (discontinued **)
Categories: Polymer; Thermoplastic; Acrylic (PMMA); Acrylic, UV Stabilized, Molded
Material Notes: Plexiglas® DR® UVA20 is an impact modified thermoplastic acrylic resin formulated for injection molding and extrusion applications. It is formulated with a special UV absorbing package, is heat resistant, has minimal edge color and provides 10 times the impact resistance of standard acrylics. It is an all-acrylic resin that combines the toughness associated with other impact plastics and the outstanding transparency and UV resistance of conventional acrylic materials.

Appearance: Clear/Transparent

Characteristics: High Clarity; Scratch Resistant; Good Dimensional Stability; Low Shrinkage; Good Thermal Stability; Good UV Resistance; Good Weather Resistance; Good Toughness; High Impact Resistance

Applications: Lighting Diffusers

Arkema has sold the American Plexiglas® product line to Trinseo, finalized in 2021.
