Apec, the copolycarbonate from Bayer MaterialScience that is mainly used in medical and lighting applications such as headlamp bezels, headlamp lenses and light housings, will now also be applied in flash lenses in smartphones. Properties such as lightweight, excellent light transparency, impact resistance and high temperature resistance make Apec a material solution that makes flash lenses more durable, says Bayer.

Bayer exploring new application areas for copolycarbonate Apec

Apec, the copolycarbonate from Bayer MaterialScience that is mainly used in medical and lighting applications such as headlamp bezels, headlamp lenses and light housings, will now also be applied in flash lenses in smartphones. Properties such as lightweight, excellent light transparency, impact resistance and high temperature resistance make Apec a material solution that makes flash lenses more durable, says Bayer.

LED lenses are becoming increasingly important on the smartphone camera market. Conventional materials are softer, and therefore more easily damaged, while using Apec also results in clearer photos with truer colors - a big plus these days, as the demand for smartphones that are able to take high-quality pictures shows no signs of abating any time soon.

Apec is a high-performance material that, says Wilfredo Aguilar, technical sales manager at Bayer MaterialScience, in fully meets the requirements of the manufacturers. "By working in close collaboration with them, we ensure that new solutions precisely meet the needs of industry and customers," he said.

Apec is a tough material offering good flowability and high dimensional stability. Unlike Makrolon, a pure polycarbonate with a glass transition temperature of approximately 150ºC., Apec is a high-heat resistant material that can be processed at temperatures of up to 200ºC.

Apec is a copolycarbonate: next to the monomer bisphenol A (BPA), small amounts of modified BPA are added to the reaction. Depending on the ratio in which the two bisphenol components are mixed, products are obtained whose heat resistance increases in proportion to the modified BPA content.
