KAPTON PEELABLE SHIMS ALKOMPOSIT K Alkomposit K laminated peelable shims are high performance shims for adjustment made from a composite material. They consist of a stack of polyimide (Kapton) leaves, joined ^^^^^^ together by gluing over the whole surface, thereby ^^^^^ forming a laminated set of compact appearance. J Each basic leaf constituting the stack can be ^^^^ peeled off extremely easily, in complete safety and by hand, until the exact thickness desired is obtained. The shim is therefore perfectly and easily adjusted to compensate accurately for the play in a mechanical assembly. They can satisfy all types of new applications where it is important to introduce concepts of insulation and lightness over a wide range of temperatures (-269°C to 400°C). Alkomposit shims can be used advantageously to replace machined or ground solid metal shims. - Low density (50% of that of aluminium) - Fineness of basic thickness: from 0.025 to 0.1mm - Cleaving without tools, by hand - Safety in use (almost zero risk - Excellent resistance to chemical - Can be used for damping or as an anti-vibration filter - Resistance to a wide range of temperatures: from - 269°C - Avoids problems of contact corrosion - Facilitates bending and adaptation to curved surfaces - Peeled leaves can be reused - Dual functionality (shimming + sealing) under certain

SHAPES AVAILABLE Alkomposit K high performance peelable shims can be produced in any geometrical shape, by cutting out or machining, to your dimensions and specifications. If the dimensions are large, it is possible to produce shims in several parts, mechanically connected or otherwise. Peelable U shims are also available in standard dimensions. THICKNESS COMPOSITION Alkomposit K peelable shims may consist solely of basic leaves of the same thickness (single composition) or of leaves of different thickness on each side (dual composition). THERMAL PROPERTIES With dual composition, the thickness...
