LEXAN 945A Polycarbonate (PC) is an injection moldable non-halogenated, unfilled transparent flame retardant grade with medium flow. It has an MVR of 10 (300°C/1.2kg) and a UL94 V0@3.0mm, and is available in various color options.
Characteristics
With an MFR of 10 g/10 min, this grade falls into the medium-flow (medium-viscosity) category for polycarbonate (PC). It is suitable for filling medium-to-thin-walled, small-to-medium-sized complex structures (such as housings or covers with wall thicknesses of 1.5–3 mm). The flow characteristics are sufficient for these applications without being so high as to cause flash or sink marks. It offers superior toughness and resistance to stress cracking, and provides better mechanical stability in thick-walled parts compared to high-flow grades.
Typical Applications
1. Electronics and Electrical
- Power adapter and charger housings; control boxes for charging piles
- Router and switch faceplates; monitor bezels
2. Automotive lighting: lenses, covers, light guides, lamp housings, and transparent instrument cluster covers
3. Lighting Optics
- LED lenses, light guide plates, and flat-panel light diffusers/covers
4. Protective eyewear, safety helmet visors, and explosion-proof lamp covers
