Polyimide Shims and Panels
Considerable weight savings can be achieved by the substitution of traditional metallic shim products with lighter weight, non-metallic materials. These include polyimide and CFRP or GFRP materials.
Polyimide has good physical, chemical and electrical insulation properties over a wide temperature range and is laminated from 0.075mm (0.003”) and 0.13mm (0.005”) films. It can be backed with a solid portion.
Composite materials also provide weight saving opportunities and can be produced as either solids or in peelable form. They are however a more expensive solution than polyimide.
