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.
