Overview
Diakon® CLG902L is a polymethyl methacrylate (PMMA) compound that offers ease of processability through injection molding and extrusion. It features a relatively high melt flow index amongst Diakon® grades and is typically used in profile extrusion applications. Like other Diakon® PMMA grades, CLG902L is made from high-quality polymers that feature high light transmission and create high optical clarity. Parts made with Diakon® CLG902L have outstanding resistance to yellowing and discoloration. Examples of parts typically made with this grade include optical lenses, electronic component housings, and medical device parts.
