The mica plate is designed for water meter columns of high pressure boilers as hydrothermal insulation.
Key parameters and dimensions:
Edged mica is a rectangular plate (plate).
The length of the plates should be no more than 220 mm, the width of the plates - not more than 35 mm.
The nominal dimensions of the plates are set by agreement between the consumer and the manufacturer.
The nominal thickness of the plates is 0.25 mm.
