Features & Benefits

Eco-Friendly Material Choice

Partially bio-circular via mass balance (ISCC PLUS), reducing carbon footprint while maintaining high-performance standards for eco-conscious manufacturing.

Superior Optical Clarity

It delivers >87% luminous transmittance (even at 4mm thickness) and <0.5% haze, ensuring crystal-clear visibility for precision lighting components.

Optimized Processing Efficiency

Low viscosity (19 cm³/10 min MVR) and easy-release properties cut cycle times and energy use, streamlining high-volume injection molding.
