5 mm black crystal glass for induction cooker with silk screen factory price CE ISO

5 mm black crystal glass for induction cooker with silk screen factory price CE ISO   Product Description   Ceramic Glass is made of a special glass-ceramic, a material with fascinating properties. This glass-ceramic has extraordinary thermal stability and resists thermal shocks of up to +700 degree C. It stands up to everyday wear and tear in the kitchen. The 4mm thick cooktop panel transmits heat very efficiently, with virtually no heat loss.   Glass ceramic is resisting to heat and cold, even to extreme temperature changes.This extraordinary property enables a variety of applications: cooking on glass ceramic appliances day after day , and protecting your fire places or stoves, still enjoying flames view.Among the heat resistant glasses, glass ceramic is really special. Its key property, is low thermal expansion, lower than borosilicate glasses or standard glasses. It means that, unlike most materials, the crystallite glass ceramic will not expand nor contract with heat. It barely changes its dimensions. This is the reason behind efficient and long time resistant cooktops.   The main physicalcharacteristics:
-Coefficient of thermalExpansionis almost reach zero
- Well temperature stability and durability
- Mechanical stability is high
- System optimization infrared transmittance
- Low thermal conductivity
