High temperature and high pressure resistant glass is the glass that can withstand high temperature and pressure. The company can provide ST5816 and ST5817 and other high temperature and high temperature resistant glass. This glass is alkali free high alumina silicate glass, with its softening temperature up to 900 degrees; it is featured by high mechanical strength and good thermal shock resistance. Moreover, it is not easily deform at high temperature, and has excellent chemical stability and thermal stability at high temperature and acidic conditions. It is widely used in automobile, household appliances, lighting, chemical industry, aerospace and other fields, such as chemical burner, high pressure water meter, cooking vessel, special lamp housing, and halogen lamp.
The supply forms include strips, cut blanks, etc. it also can be customized according to customer requirements.
