VYCOR® DISK AND SHEET

Vycor®

96% silica VYCOR® glass is ideal for high temperature applications, to the extent where it can be used continuatively up to 900°C and, for periods times, up to 1200°C. Owing to its very low thermal expansion coefficient VYCOR® also guarantees excellent thermal shock resistance. VYCOR® windows can be supplied in circular, square or rectangular format. Maximum size is 310 mm.
