Features & Benefits
Outstanding Impact Strength & Toughness
With remarkably high notched Izod impact values (774 J/m at 23°C), LEXAN EM1210 resists cracking and damage from everyday impacts and stress, reducing part failure and warranty claims in components like panels and brackets.
Superior Heat Resistance for Interiors
Featuring a Heat Deflection Temperature (HDT) of 127°C at 1.82 MPa, this resin maintains its shape and rigidity even when exposed to high cabin temperatures from solar loading, ensuring dimensional stability for parts near windows or dashboards.
Consistent Performance in Extreme Climates
LEXAN EM1210 retains excellent impact and mechanical properties from -30°C to well over 100°C, guaranteeing that interior parts won’t become brittle in winter or soften in summer, providing year-round reliability.
