Features & Benefits
Exceptional Impact Resistance
With high notched Izod and Charpy impact values, even at -30°C, LEXAN AT2030R ensures components withstand sudden shocks and harsh environments, reducing failure rates in automotive exteriors.
Reliable Thermal Performance
Featuring a Vicat softening point over 140°C and strong HDT ratings, this resin maintains structural integrity under high temperatures, perfect for parts exposed to engine heat or summer sun.
Superior Dimensional Stability
WitLow moisture absorption and consistent mold shrinkage (0.5–0.7%) ensure precise, stable part dimensions over time, critical for tight-tolerance assemblies like sensor covers and panel fits.
