                                                                                       Borosilicate Heat-resistant Glass 3.3(BG3.3)

Product Introduction

The main characteristics of high borosilicate glass 3.3 are: no peeling, non-toxic, tasteless; Good transparency, clean and beautiful appearance, good barrier, breathable, high borosilicate glass material, has the advantages of high temperature resistance, freezing resistance, pressure resistance, cleaning resistance, not only can be high temperature bacteria, can also be stored at low temperature. High borosilicate glass is also known as hard glass, is an advanced process made of processing. 

 This revolutionary glass is made of borosilicate, a special material that combines strength and durability with an extraordinarily high heat resistance. 

Whether it's functional or decorative, this magnificent material will make any project look great while helping protect against extreme temperatures up to 500°C (932°F). And because of its excellent thermal shock properties, it won't cloud over time from frequent temperature fluctuations either! 

High borosilicate 3.3 glass is high-temperature resistant glass, heat-resistant glass and temperature difference resistant glass. The linear expansion coefficient is 3.3 ± 0.1 × 10-6 / K, is a glass with sodium oxide (Na2O), boron oxide (b2o2) and silicon dioxide (SiO2) as the basic components. The content of boron and silicon in the glass composition is relatively high, namely, boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%.

The expansion coefficient will affect the stability of glass. The expansion coefficient of borosilicate 3.3 heat-resistant glass is 0.4 times that of ordinary glass. Therefore, at high temperature, borosilicate 3.3 heat-resistant glass still maintains excellent stability and will not crack or break.

Feature

Advantages

• Fire protection duration exceeding 2 hours
  

• Outstanding mechanical strength, 8-10 times stronger than ordinary  glass
  

• Small specific gravity, more than 8% lighter than ordinary soda lime silica glass

• Higher light transmittance 
  

• Stable chemical property

• Without self-explosion

• Excellent ability at thermal shack
  

When it comes to the use of borosilicate glass semiconductor chip technology, there are many advantages to this material over traditional silicon-based chips.

 1.borosilicate can handle higher temperatures without its properties becoming affected by heat or pressure changes like silicon would when exposed to extreme conditions. （This makes them ideal for high-temperature electronics as well as other products requiring precise temperature control—such as certain types of lasers or x-ray machines where accuracy needs to be paramount due to the potentially dangerous nature of the radiation they emit if not properly contained within their housing materials）

2.Borosilicate's remarkable strength means that these chips can be made much thinner than those using silicon wafers – a major plus for any device needing miniaturization capabilities such as smartphones or tablets with very limited space inside them for components like processors or memory modules which require large amounts power yet have low volume requirements at the same time . Additionally , because these materials don't suffer from oxidation (rusting) like metal parts do , they're perfect for long-term reliability in harsh environments where exposure could lead regular metals corroding away over time.

3. Borosilicates' excellent electrical insulation properties make them great candidates for complex circuitry designs where insulation between each layer is essential in order prevent short circuits occurring during operation – something that’s especially important when dealing with high voltages which could cause irreversible damage if allowed unchecked currents flowing through sensitive areas on board .  All this combines together making borosilicate glass 3.3 an exceptionally suitable solution whenever needing highly durable materials performing reliably under extreme conditions while providing exceptional electrical isolation.
