Mica Gasket
WL-2082
Description
In many applications when oxygen is present and the temperature is over 850 F the ideal sealing material flexible graphite cannot be used. Flexible graphite will coke at those elevated temperatures when oxygen is present.An excellent alternative in many applications is mica. Some of the basics on mica are shown below. As a gasket material mica can be very effective in sealing those high temp critical applications with out failing due to the presence of oxygen.Mica gaskets are laminates made from Mica impregnated with resin, stacked and pressed at high temperature and pressure to achieve polymerisation.
Consists of muscovite or phlogopite,mica sheet(paper) impregnated with specially selected epoxy resin.It can be sawed, sheared and punched into intricate shapes.Because of its superior uniformity, automatic feeding and stacking are possible and high speed assembly operations.
Application of Mica Gasket
-
Supports for heating resistors (i.e. convectors).
-
Thermal insulation in circuit breakers and between electronic components
-
In large thickness, as thermal insulators for industries with large stress such as
iron and steel works, chemical, glass and petro-chemical industries -
Mechanical support and electrical insulator in high voltage cabins
-
Replacements for asbestos panels in forging machines and hydraulic presses

Warning: Gasket materials should never be recommended when both the temperature and the pressure are at the maximums listed. Properties and applications shown are typical. No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket. Improper use or gasket selection could cause property damage and/or serious personal injury. The data reported is a compilation of field testing, field service reports and/or in-house testing. While the utmost care has gone into publishing the information contained herein, we assume no responsibility for errors.
