Arkema's Altuglas International Business Achieves New Level of Heat Resistance with Plexiglas HT121 Acrylic Resin

Plexiglas® HT121 acrylic resin, which is sold under the Plexiglas® brand name in the Americas and the Altuglas® brand name in the rest of the world, is an acrylic resin suitable for a variety of high heat applications.  The product has received a UL classification in the Relative Temperature Index (RTI) of 100°C.

The 100°C classification is the highest RTI classification for an acrylic resin in the Plexiglas® product line.  The classification compliments Altuglas International's existing product line and reinforces its commitment to providing solutions to its customers.  Along with the new RTI classification, Plexiglas® HT121 acrylic resin has also achieved the (f1) UL weathering standard, which means the material is suitable for outdoor use with respect to exposure to ultraviolet light, water exposure, and immersion in accordance with UL 746C.

"Our ability to offer Plexiglas® HT121 acrylic resin for high heat applications is another opportunity for us at Altuglas International to differentiate ourselves in the market," said Business Manager Jim Litkovitz. "As with all Plexiglas® acrylic resins, Plexiglas® HT121 acrylic resin is weatherable, easily processed, UV stable and has excellent clarity.  Altuglas International is proud to expand our excellent product line with the new RTI and qualification achievements," Litkovitz added.

Plexiglas® HT121 acrylic resin is suitable for LED lighting, automotive optic plates, and reflex reflectors or light guides, along with signage and any application requiring a more heat resistant acrylic resin.
