HAYABEADS L-11 SERIES
White Cell Spacer for LCD
Features
- HAYABEADS is the best chemical stability and reliability because it is made of 100% Acrylic resin
- HAYABEADS is high performance of dispersion
- HAYABEADS can make panels with smaller number of spacers, because of its hardness
- HAYABEADS can make delicate gap controlling, because of high recoverability after compression
- HAYABEADS is high performance at high temperature and after heating
