Description                            

Longhua L-x/LonghuaL-xx product line is light-guided PC base film offering high polish and different textures. It is provided with outstanding optical transmittance as well as featured with great heat-resistance, foldability and flexibility, excellent dimension stability, low stress and minimized color differentiation. It supplements disadvantage of traditional fragile light-guided PMMA plates, provided with a variety of thickness choices. Popularly used for monitors, NB, GPS, MP, LED keypads, graphics, labels and luminaire, etc. Great printability and heat formability make it a good choice for modules or thinner LGP with enhanced luminance.
