Insulating And Sheathing Materials
When designing the best possible cable for the customer, the choice of the right insulation and sheathing material plays a decisive key role.
Thus, in addition to the requirements for the cable itself (required functions and service life), external influences such as ambient temperatures, temperature fluctuations, UV radiation, mechanical stresses (e.g. due to movement, bending, friction, tension, torsion), chemical influences (contact with oils, greases, chemicals) and the mutual influence of the materials on each other must also be taken into account. Added to this are requirements for environmental compatibility (recyclability), fire behavior (functional integrity in the event of fire, fire continuation, smoke gas development) and, of course, costs.
In practice, it is almost always a combination of different criteria that influences the choice of material.
The Course of Time
Time heals all wounds - unfortunately, this does not apply to plastics. Here, aging processes take place continuously, which are accelerated, in some cases significantly, by the effects of the previously mentioned influences. Continuously changing stresses lead to material fatigue, the materials become brittle, porous or deform - which can lead to premature failure of the cable and thus to failure of the entire system.
The Combination Matters
HEW-KABEL has a wide range of different plastics that can be modified characteristically and optimally adapted to the intended use by adding special additives or by using special manufacturing processes.
