Overview of INTERCOMPOSITE® laminated shims

  

INTERCOMPOSITE® laminated shim

is a unique LAMECO material, designed and patented by Daniel GASTEL, made of a polyethylene glycol terephthalate film obtained by a slit-die extrusion process, followed by a double-drawing.

Advantages of INTERCOMPOSITE® laminated shims

  

Lightness
As an answer to a weight saving requirement. INTERCOMPOSITE® is one of the lightest of laminated materials.

Good physical, mechanical, thermal and chemical characteristics
INTERCOMPOSITE® is twice as light as Aluminum, but with equivalent thermal resistance. See the tables of characteristics here below.

Anti-fretting
INTERCOMPOSITE® is a total barrier against the galvanic coupling caused by surface contact of different metallic alloys. No further surface treatment is required.

Adaptation to curved shapes
INTERCOMPOSITE® has the property to immediately adapt itself to most curves profiles without any loss of precision. And this can be performed in site.

Facility and rapidity of use
You can peel INTERCOMPOSITE® with your forefinger (no tools being necessary) and once peeled the sheets are reusable.

Safety
INTERCOMPOSITE® is easily peeled without risk of finger cuts.

Low cost
INTERCOMPOSITE® is the least expensive of all our laminated materials.
