MATERIALS

Due to the fact that HangOn produce both hanging and masking products a lot of different materials are used. To know a little more about possible uses and limitations we present some materials and corresponding physical properties here.

* In powder coating some materials can be used just once, for example EPDM which has a top temperature resistance of 125°C but
  can actually stand temperatures up to approx. 200°C. EPDM plugs get harder but do not melt.

** Thermoplastics like PA actually start melting at approx. 160°C but can be stabilized in some different ways, for example with a
    mixture of glass fibres.

SOME FACTS ABOUT LOAD CAPACITY

Load capacity of a single hook is dependent on many things, the most important is material, wire diameter and orthogonal distance. An approximate formula true for a single hook:

Mmax ≈  σs * ø³/99,5e

Mmax = load where irreversible deformation starts (kg)

σs = bending strength (N/mm2)

e = orthogonal distance (mm)

Typical dynamic behaviour of standard hooks when loaded is that maximum load, the load where the wire starts to be permanently deformed (bending strength) is the same for DV and R but approximately double for DV M.
Then DV and DV M describes a “concave” load-extension line before the load falls or drops off, while R looks more like a convex figure.

Due to the shape of the hook the load capacity after irreversible deformation limit and safety margin are very different. R hooks have a low margin and DV much higher. DV/DVM shape is therefore a safer choice.

USER GUIDE MATERIALS

WEIGHT:
»     Consider that the static weight can be doubled or more when
       hanging and in slopes and curves.
»     Wire hooks are stretched by bending and if reformed later, this might cause cracking.
»     Burn off, blasting, or penetration by strong chemicals etc might reduce material strength.

CHEMICALS:
»     Most materials used in HangOn products withstand normal pretreatment chemicals.
»     If actual hook material does not withstand chemicals,
       probably the first coating layer will be protective enough.

BLASTING:
»     Most HangOn materials withstand mild blasting.
»     In more aggressive blasting thicker material last longer.
       Example of masking materials for blasting is EPDM, PVC and glass fibre.

TEMPERATURE:
»     Oven max temperature, temperature curve, object surface temperature, time, and
       how a masking product is positioned all have an impact on the final result.

 

OUR RECOMMENDATION:
»      Ask your HangOn contact for an opinion.
»      Always test the product in actual application.
