SGF

Switchable Glazing Film

Next-Generation Optical Control Solution for Future Mobility Spaces

SGF (Switchable Glazing Film) is a next-generation optical control material that allows users to freely adjust optical transmittance with electrical voltage. Its structure features an optical control layer positioned between two electrode films, providing clear visibility in the ON state and effective light blocking with enhanced privacy protection in the OFF state.

As electric vehicles and glass roofs become more widespread, cars are evolving from simple “driving spaces” into immersive “experience spaces.” SGF is a key solution designed to meet this shift, offering differentiated design and a premium aesthetic. Leveraging advanced material technologies, LG Chem delivers a complete suite of SGF products to elevate the value of future mobility.
