Key technical data

Rheology
  • Low shrinkage (0.7–0.75%) ensures dimensional stability in precision molds.
Mechanics
  • Exceptional impact resistance (70 kJ/m²) and flexibility (>120% strain) suit crash-relevant parts.
Thermal
  • HDT of 124°C supports under-hood/glazing applications.
Electrical
  • High CTI (250) and volume resistivity (10¹⁴ Ω·m) enable use in automotive electronics.

Application

  • Automotive Glazing: Sunroofs, side windows, and panoramic roofs (replacing glass for 50% weight savings).
  • Roof Modules: Integrated solar/lighting panels requiring UV stability and optical clarity.
  • Injection-Molded Components: Complex parts like headlamp lenses or sensor housings needing precision molding.

Features & Benefits

Optical Clarity & UV Resistance

It delivers 88–89% luminous transmittance (3 mm thickness) and low haze (<0.8%), ensuring crystal-clear visibility while resisting yellowing in outdoor automotive use.

Impact Resilience for Safety

It boasts 70 kJ/m² notched impact strength (23°C), enabling lightweight yet shatter-resistant glazing that meets stringent automotive safety standards.

Thermal Stability Under Load

With a heat deflection temperature of 124°C (1.8 MPa), it maintains structural integrity in high-heat environments like sunroofs or lighting housings.
