Product Description
For compressive stress with temperatures,Borosilicate circular sight glass work up to max. 280 degrees Celsius Where a greater degree of chemical resistance or higher operating temperatures are required a borosilicate glass should be specified.In a toughened form temperatures up to 315 degrees Celsius are possible whilst annealed glass may be used up to 400 degrees Celsius continuously with a short term maximum of 500 degrees Celsius.Borosilicate is the most commonly used material due to its low cost.It can be easily toughened to effectively increase the mechanical strength of annealed glass by up to five times.It is available in different sizes depending on customer request.
