Sabic said that it is introducing new materials for customers producing LED automotive lighting parts.
Lexan HF4010SR resin is one of the new offerings. This polycarbonate (PC) material can make it possible for customers to develop complex headlight bezels with enhanced aesthetics. Sabic has also added new grades to its existing Lexan XHT resin line, which can offer improved flow at high temperatures compared to other high-heat polycarbonate materials available today.
Sabic’s new materials targeting forward lighting parts come at a time when the complexity of these applications continues to increase. Current high-end LED headlamps weigh close to six kilograms with up to 200 components, thanks to the additional functionality they incorporate. Automakers are also striving to create highly distinctive lighting parts to help differentiate and increase the appeal of their vehicles.
Sabic has engineered the new Lexan resin to address customers seeking to produce complex headlamp bezels with enhanced styling, but at a lighter weight and at a lower overall system cost.
“These new offerings are examples of how we listen to our automotive lighting customers, stay in touch with their emerging needs, and propose materials they can consider to meet the challenges in front of them,” said Scott Fallon, global leader of Sabic’s automotive business.
New materials for complex headlamp bezels – Lexan HF4010SR resin
When designing injection-moulded parts, a low draft angle is important because it enables greater styling freedom as well as a larger optical surface. However, the lower this angle, the more problems arise with parts sticking in the mould, creating scuff marks and potentially even resulting in a part with cosmetic defects.
To help the industry meet this challenge, Sabic has developed Lexan HF4010SR resin. This material can enable customers to target draft angles between 0.5 and 1.0 degrees lower than the recommended draft angle for PC tools (typically between 3 and 5 degrees).
Bezels that are injection moulded in Lexan HF4010SR can be directly metallized (no need for priming) and gloss and reflectivity performance under high-temperature environments are both very good. The material has a unique wide processing window and high flow. Parts perform in environments requiring a maximum constant use temperature of up to 130°C.
