Glass ceramic

Technical Specifications of Glass Ceramic Description: Crystallite 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. Applications:  Vision panels for room heaters, glass heaters, glass heating tabletops, heat preservation board/panels;  Cover panels for heating radiators, drying stand, towel heaters;  Cover panels for reflectors and high performance floodlights  Cover panels in IR drying appliances  Cover panels for beamers  UV blocking shields  Cover panels for kebab grill radiators, electric heating fish bowl Quality Assurance: 1, Density---approx. 2.56 g / cm3 2, Modulus of Elasticity--- approx. 93 x 103 Mpa 3, Bending Strength--- approx. 36 MPa The bending strength testing is to be accomplished according to DIN EN 1288 part 5 (R45). 4. Thermal Characteristics Coefficient of Mean Linear Expansion---α(20 - 700oC) (0 ± 0.5) x 10-7 /K 5. Resistance to Temperature Differences (RTD) Resistance of the panel to temperature differences between heated zone and cold panel edge (room temperature). No cracking due to thermal stress at Tes, max1<=700 degree C 6. Thermal Shock Resistance Resistance of the panel to thermal shock when the hot panel (780 degree C) is quenched with cold water (20oC temperature). No cracking due to thermal stress at Tes, max<=700 degree C 7. Chemical Characteristics of Base Material Acid Resistance--- DIN 12116: at least class S3 Alkaline Resistance---based on ISO 695: at least class A2 8. Screen printing: complies with RoHS standards, normal ink available 9. Impact resistance: A steel ball (diameter 60mm, weight 188g) freefall from180mm height, striking the panel 10 times. No scratching or cracking. Cleaning & Care hints: First, wipe down the glass-ceramic panel with a clean, damp cloth. Then rub the panel in a circular polishing motion using a soft cloth and a few drops of a conditioner suitable for use on glass-ceramic cooktop panels. Then rinse with a damp cloth and wipe dry with a clean, soft cloth. After rinsing and drying, the surface is coated with an invisible film which helps to keep the panel clean. Regularly repeating this conditioning process makes it considerably easier to keep the panel clean and shiny.
