Developed to resolve issues with glass deformation and thermal compaction in the manufacturing process, strain point of this glass is higher than that of soda-lime glass. We provide CP600V and CP600N.
Applications
Glass substrates for electronic industries
Features
- 1.High strain point
High heat resistance, controls thermal deformation and thermal compaction - 2.Stable product quality
Production in float lines incorporating new technology and know-how allows stable supply of high-quality products. - 3.Responsive to customer needs
We are able to respond flexibly to sheet thickness, size and other needs. - 4.Environmentally friendly composition
For our glass composition, we have selected environmentally friendly raw materials with little depleting potentiality.
Composition
SiO2 -Al2O3- R2O- R'O-ZrO2series (R:Na, K R':Mg, Ca, Ba)
