Features & Benefits
UV Resistance for Longevity
Formulated with UV stabilizers, LEXAN AT1230R resists yellowing and degradation, ensuring lasting appearance and performance in outdoor and automotive exposed parts.
Exceptional Impact Strength
Even at low temperatures (-30°C), this resin maintains high notched impact resistance, reducing the risk of cracks or breaks in demanding environments like vehicle sensor housings.
High Thermal Stability
With a Vicat softening point above 140°C and strong HDT values, LEXAN Resin AT1230R withstands high-temperature exposure, ideal for under-hood components and exterior panels.
