BTG 180 minutes high borosilicate fireproof glass 4.0

• Product introduction

The BTG borosilicate monolithic fireproof glass is formed by tempering an original piece of glass produced by a high borosilicate floatation process. Its fire resistance is derived from its very low coefficient of thermal expansion - only 4 x 10 -6 (20-300 ° C), which is 2 to 3 times lower than ordinary glass (silicate glass). In addition, BTG borosilicate monolithic fire-resistant glass also has a high softening point, excellent thermal shock resistance and viscosity. Therefore, when a fire occurs, the BTG borosilicate monolithic fireproof glass is not easily expanded and broken, and is a high stability single piece fireproof glass with a fire resistance time of up to 3 hours.

• Excellent performance of BTG borosilicate 4.0

1. 4×10 -6 (20-300°C) thermal expansion coefficient, 2-3 times lower than ordinary glass (silicate glass), creating over 3 hours of fire prevention time

2. 851 ° C ultra-high softening point, escort for fire stability

3. No NiS crystallization, sweeping away the danger of self-explosion

4. Fully tempered single piece fire resistant glass for double safety requirements

5. 90% high light transmittance, low iron formula to meet the true color rendering

6. Superior borosilicate optical quality for undistorted visuals

7. 2.28g/cm3 (25°C) density, low self-weight to keep small body

9. Ultra-high mechanical strength makes it light and contains unlimited power

10. Good corrosion resistance, stable and not afraid of UV

• The maximum sizes of BTG boron silicon 4.0 are 6mm and 8mm

 Performance Parameters

Size: The performance of fireproof glass will be reduced due to the increase of size. Generally, the design of fireproof glass monolithic size for 3 hours does not exceed 1500*1500.

Frame system: 3-hour fireproof glass requires special steel frame system and refractory material to prevent the glass from falling off after softening
