ALKOMPOSIT LAMINATED PEELABLE SHIMS

nnnn

Alkomposit laminated peelable shims are shims for adjustment

nnnn

made from a composite material. They consist of a stack of basic

nnnn

polyester (Mylar) leaves, joined together by gluing over the whole

nnnn

surface, thereby forming a laminated set of compact appearance.

nnnn

Each basic leaf constituting the stack can be peeled off extremely

nnnn

easily, in complete safety and by hand, until the exact thickness

nnnn

desired is obtained. The shim is therefore perfectly and easily

nnnn

adjusted to compensate accurately for the play in a mechanical

nnnn

assembly.

nnnn

They can satisfy all types of new applications where it is important

nnnn

to introduce concepts of insulation and lightness over a wide range

nnnn

of temperatures (see properties overleaf). Alkomposit shims can be

nnnn

used advantageously to replace machined or ground solid metal

nnnn

shims.

nnnn

Alkomposit Viewtek laminated peelable shims are dual

nnnn

composition adjustment shims (that is, consisting of basic leaves

nnnn

of a different thickness on each side) using an exclu-

nnnn

sive, original and patented marking process.

nnnn

They therefore offer a convenience in use

nnnn

that is unequalled to this day. Owing to the

nnnn

marking written in full over the whole

nnnn

surface, you can see immediately, and with

nnnn

no risk of error, the thickness of the basic

nnnn

leaves you are removing to obtain the desired

nnnn

final dimension. These are the first shims that can

nnnn

r be peeled off with the fingers and by eye.

ADVANTAGES:

nnnn

- Low density (50% of that of aluminium)

nnnn

- Fineness of basic thickness: from 0.025 to 0.1mm

nnnn

- Cleaving without tools, by hand

nnnn

- Safety in use (almost zero risk of

nnnn

cuts)

nnnn

- Excellent resistance to chemical

nnnn

agents

nnnn

- Immediate identification of basic

nnnn

thickness by the exclusive, patented Viewtek process

nnnn

(marking + colour code: 0.025mm, 0.05mm and 0.10mm)

nnnn

- Can be used for damping or as an anti-vibration filter

nnnn

- Resistance to a wide range of temperatures: from - 70°C

nnnn

to + 220°C

nnnn

- Avoids problems of contact corrosion

nnnn

- Facilitates bending and adaptation to curved surfaces

nnnn

- Peeled leaves can be reused

nnnn

- Dual functionality (shimming + sealing) under certain

nnnn

conditions
