Mechanical Properties

The standard work material of the KINGNUT nuts is non-reinforced Type 6.6 polyamide.

The following details refer to tests over a short period conducted under normal climatic conditions. In accordance with the guidelines of the general test standards for plastics, the nuts were stored at least 24 h with test conditions and before check at least 48 h after production.
23°C ambient temperature and 50 % rel. Air humidity conditioned.

Longtime Properties

The elastic-viscous properties of the material cause the mechanical characteristic values to decrease during temporal load conditions. The above short-term values should therefore be reduced accordingly.

On special customer's request more detailed information for special applications can be given following simulation of the load application by FEA (Finite Element Analysis). This applies for both static (creep and relaxation tests) and dynamic considerations (load change reactions, inherent frequency).

Conductivity

The KINGNUT nut is basically an electric non-conductor.

Volume resistance: 1E15 Ohm*cm
Surface resistance: 1E13 Ohm*cm


Influence of Temperature

The above mechanical characteristics value were determined at 23° C.
This values retain their relative validity in temperature range of -10 to +40 deg.C.

Thermal application range of the KINGNUT nut: -10 to +75 deg.C with basic material,
up to 300° C with PPS.   Thermal stability: 220° C.

These values can be increased significantly by use of special materials.


Behavior in Fire

UL94 Flammability Class: V-2

Flammability Class V-0 can be achieved with additives.


Influence of Environmental Conditions

The KINGNUT nut is resistant against

*UV-exposure
*Corrosion
*Acids pH > 1,5 to 40 deg.C.
*Alkaline solutions up to pH 11

Special requirements can be met by selection of suitable plastics.


Life

20 years exposure to weather
10 years exposure to chemicals


Recycling

The use of non-reinforced plastic permits recycling together with other materials and material recycling.

With appropriate incineration (thermal utilization) no compounds detrimental to health are generated.
