Features & Benefits
Superior Optical Clarity
With 89% light transmission and extremely low haze (<0.8%), LEXAN AD143 produces crystal-clear parts. This ensures vibrant, distortion-free visibility for lenses, covers, and displays, enhancing product aesthetics and user experience.
High Impact & Mechanical Strength
This resin delivers outstanding toughness, even at low temperatures. Its high notched Izod impact strength reduces the risk of cracking or failure from drops or impacts, leading to more durable and longer-lasting components.
Excellent Thermal Stability
Featuring a high Heat Deflection Temperature (HDT up to 130°C), LEXAN AD143 maintains structural integrity in elevated temperature environments. This allows for reliable performance in applications exposed to heat, such as under-hood automotive parts or sterilizable medical devices.
