Peel-Away Layered Shim Stock
Cut this shim stock it into custom shapes to fit your application. Stock is made of layers of material bonded with adhesive; remove layers with a utility knife until you get the thickness you need. To make the layers easier to pull apart, gently heat the shim to soften the adhesive.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Polyimide plastic shim stock is corrosion resistant, electrically insulating, and holds its shape at extreme temperatures. It's easier to peel apart than metal shim stock. Stock includes a material certificate with traceable lot number and test report.

Crack-Resistant Rigid Polyimide Insulation Sheets
Even when subjected to heavy compression, these rigid polyimide sheets won't crack. To use outdoors, add metal jacketing.
Sheets with a density of 12 lbs./cu. ft. are easier to cut than denser polyimide insulation sheets, which makes them good for die-punching applications. They are not, however, good for machining.
Sheets with a density of 60 lbs./cu. ft. are more durable than less dense polyimide insulation sheets, so they can stand up to machining. They’re often used for mold bases or press insulation.
