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.
Use & Applications
- Extrusion: Durable profiles for conveyor systems, protective edging, and architectural trim.
- Solid Sheet: Shatter-resistant windows for factories, safety visors, and transparent machine covers.
- Corrugated Sheet: Weather-resistant roofing for greenhouses, warehouses, and stadiums.
