PMMA Sheet 타이틀
The Optical PMMA Sheet strengthens the purity of Resin and physical characteristics required to the demand characteristics of window of several optical display devices such as the light transmittance, surface hardness and impact strength
1. It is excellent of transparency using high purity optical Resin
2. It is used as window of several display because it has good surface hardness and light transmittance.
3. It has low post-modification because of less water absorption.
4. It has low loss when post-pressing because of specification of optimal production when pressed.
Cell-phone window, Monitor window, Several Display Window, LED light cover.
