Application

  • LED Light Guides: Edge-lit panels, automotive taillights, and backlit displays requiring uniform diffusion.
  • Optical Lenses: Thin-walled lenses for sensors and consumer electronics.
  • Transparent Housings: Protective covers for indicators and control panels.
  • Precision Components: Medical device light pipes and touch-screen interfaces.

Features & Benefits

Unmatched Optical Clarity

Achieve crystal-clear light diffusion with luminous transmittance >89% (up to 4mm thickness) and haze <0.5%. Ideal for LED lenses and displays where brightness uniformity is critical.

Superior Process Efficiency

High melt-flow (34 cm³/10 min) enables easy filling of thin-walled geometries (e.g., micro-optics), reducing cycle times and energy costs in injection molding.

Thermal & Mechanical Resilience

It withstands 138°C deflection temperatures (0.45 MPa) and offers high impact strength (60 kJ/m² notched Charpy). Ensures durability in automotive or outdoor LED housings.
