Application

  • LED Lighting: Diffuser plates, lenses (uniform illumination).
  • Electronics: Flame-retardant housings (connectors, power units).
  • Transportation: Interior components (overhead panels, trim).
  • Extrusion Profiles: Light guides, signage with UV stability.

Features & Benefits

Superior Flame Resistance

It achieves UL 94 V-0 (0.8 mm) and 5VA (3.0 mm) ratings, ensuring compliance in electronics and automotive interiors where fire safety is non-negotiable.

Optimized Light Diffusion

It delivers luminous transmittance up to 67% (1 mm) with wide half-power angles (44°–58°), eliminating hotspots in LED fixtures and displays.

Thermal & Processing Stability

Vicat softening at 143°C and tailored melt viscosity (240–1840 Pa·s) enable consistent injection molding or extrusion of complex, heat-resistant parts.
