Features & Benefits

Unmatched Impact Resistance

Makrolon ET3113 withstands heavy impacts (e.g., 60J puncture energy at 23°C), reducing part failure in high-stress environments like machinery guards or safety barriers.

Superior Optical Clarity & UV Stability

Boasting 88% light transmission (3mm thickness) and <0.8% haze, it maintains transparency and resists yellowing under sunlight—ideal for skylights or display panels.

High-Temperature Resilience

With a Vicat softening point of 148°C and HDT of 128°C (1.8 MPa), it performs reliably in hot settings like automotive components or outdoor structures.
