The company has Shi Ying bars with diameters of 2, 3, 4, 5, 6, 10, 20 mm, etc.  Application: Used for bridge pressing rod of single-end halogen lamp, optical fiber lighting, Shi Ying fiber manufacturing, semiconductor silicon wafer processing, etc.  The transparent Shi Ying rod has the characteristics of high purity, high temperature resistance and low thermal expansion coefficient, and is used for bridge pressing rods of single-ended halogen lamps, optical fiber lighting, manufacturing of Shi Ying fibers, processing of semiconductor silicon wafers, and the like.  Characteristics of Shi Ying glass: 1. High temperature resistance. The softening point of Shi Ying glass is about 1730 degrees, which can be used for a long time at 1100 degrees, and the maximum temperature in a short time can reach 1450 degrees.  The softening point of the glass is about 700 degrees.  2. Corrosion resistance.  Apart from hydrofluoric acid, Shi Ying glass hardly reacts with other acids, thanks to the fact that Shi Ying glass is made of pure atomic crystal - silicon dioxide, its acid resistance is 30 times that of ceramic and 150 times that of stainless steel, especially its chemical stability at high temperature is incomparable to any other engineering material.  3. Good thermal stability.  Shi Ying glass has a very small coefficient of thermal expansion and can withstand severe temperature changes. Shi Ying glass will not crack when it is heated to about 1100 degrees in normal temperature water.  4. Good light transmission performance.  Shi Ying glass has good transmittance in the whole spectrum band from ultraviolet to infrared, with visible light transmittance above 93 %, especially in the ultraviolet spectrum region, the maximum transmittance can reach above 80 %.  5. Good electrical insulation performance.  The resistance value of Shi Ying glass is 10,000 times that of ordinary glass. It is an excellent electrical insulation material and has good electrical properties even at high temperatures.
