REXI high borosilicate glass (also known as hard glass) is made of the conductive property of glass at high temperature, through heating inside the glass to achieve glass melting, processed by advanced production technology, because of the linear thermal expansion coefficient of (3.3 × 0.1)×10-6/K and(4.0 × 0.1)×10-6/K  also known as "borosilicate glass 3.3"and "borosilicate glass 4.0", It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, process jewelry and other industries, Its good performance has been widely recognized by all circles of the world, especially in the field of solar energy is more widely used, Germany, the United States and other developed countries have been more widely promoted.

FEATURES:

·Borosilicate glass has a very low coefficient of thermal expansion, about one third of that of ordinary glass. This will reduce the stress caused by temperature gradient Therefore, it has stronger fracture resistance. Because its shape deviation is very small, this makes it an essential material for telescopes and mirrors. It can also be used to dispose of high-level nuclear waste..  

·The borosilicate glass begins to soften at approximately 821 ℃(1510 ℉), Borosilicate glass is less dense than ordinary glass

·Optics, borosilicate glasses have low dispersion (about 65 abbe crowns) and a relatively low refractive index (1.51-1.54 across the entire visible range)..

·Acid, alkali and water resistance, excellent corrosion resistance, with good thermal stability, chemical stability and electrical properties, so it has chemical corrosion resistance, thermal impact resistance, good mechanical properties, high temperature resistance and other characteristics

APPLICATIONS:

REXI Borosilicate Glass can supply excellent fire resistance and good impact resistance glass.

·All doors (sliding, swing, etc).

·High borosilicate glass for halogen lamp reflective heat resistant lamp cup and must use heat resistant glass electrical equipment, such as microwave oven special glass turntable, microwave oven lampshades, stage light reflection cup, roller washing machine observation window, heat resistant teapot tea cup, solar collector, etc

·Building door, window, curtain wall

·Lighting roof and partition wall without heat insulation requirements

·Locomotive Glass

SIZE: 1700*1150*4.0mm，3600*2440*(5.0-12)mm, Other specifications can be produced according to customer requirements
