Heat Resistance

PMMA Heat Resistance - ALTUGLAS™ Acrylic Resins

Our pure ALTUGLAS™ acrylic resin for injection and extrusion exhibits the greatest heat resistance on the market. As light sources become more powerful and light fittings more compact, internal and external optical elements need a combination of high quality light transmission and thermal resistance. Automotive exteriors (black pillars and decorative parts) need to be resistant to heat and weathering from sun exposure.


This is the material of choice for optical and aesthetical applications requiring thermal resistance combined with outstanding UV (AMECA certification) & scratch resistance. ALTUGLAS™ HT 121 grade is typically used in sensitive automotive tail light and cluster lens designs, household appliances and displays.
