»Low-weight precision work« for efficient thermal insulation

Polyethylene and polyvinylidenfluoride provide excellent properties for the production of insulation bodies for aircraft manufacturing: Low weight and high insulation efficiency, mechanical durability, dimensional stability and durability, chemical resistance to aggressive media and temperature resistance, closed-cell structure (no moisture permeability, therefore no weight gain)

It is crucial what you do with it.

At a first glance, low material density and highest dimensional accuracy seem to be diametrically opposed. Wulfmeyer processes selected high-quality PE and PVDF foam and has developed production strategies that ensure high precision when producing insulation bodies.
