DESIGN CONSIDERATIONS - Section 5 Material Properties
Properties Of Nylon Cable Carrier Systems In Different Environmental Conditions
KS has materials suitable for harsh or extreme indoor as well as outdoor applications. Standard Polymer Operating Temperature Range: -40° F (-40° C) to 266° F (130° C)
Environment
It is recommended to use our special hot or cold temperature materials or our steel chain systems, when sustained operating temperatures remain below -13° F (-25° C) or above 185° F (85° C). Once either of these levels is eclipsed, the mechanical values are reduced and service life degraded. Please consult KabelSchlepp for a suitable solution. Chemical, flame, debris, UV and temperature resistant materials are readily available whenever required.
Nylon cable carriers can also be used in vacuums. In the case of intermittent loads the traction forces occurring should be ascertained. Please consult our factory in every such case.
Vacuum
With a dose of up to 1 megarad the material does not deteriorate. When the dose is increased to 100 megarads the material becomes steadily more brittle. The maximum limits of the mechanical properties drop by 30% at 100 megarad. Where the dose exceeds 100 megarad . the use of nylon cable carriers is not recommended. Please consult our factory in these cases. According to the testing process in line with VDE 0304 Part 3 (05.70) the standard material (KS-PA, reinforced with glass fiber) corresponds to classification II c. Tested in line with UL 94 - ASTM 0635-81 Classification: “UL 94-HB” Tested in line with DIN 4102, “Burning characteristics of construction materials and component parts” Classification: Construction material class B2, minimum thickness < 1 mm, not dropping if burning.
Resistance to Radiation
Flammability
For plastic cable carriers able to withstand cold storage areas, a special material is used. These cable carriers can only be produced in yellowish/ white (transparent).
Resistant to cold storage
Cable carriers for use in areas at risk of explosion or static discharge resistant, are produced from a special material and are only available in black. Since there is nothing to differentiate them by sight from standard cable carriers, these cable carriers are identified with a stamp marked “ EX ”. ■ Flash point of special material: 536° F (280° C)
Ex-protected cable carriers
■ Ignition temperature of special material: 779° F (415° C) ■ Surface resistance: <10 5 Ω (Standard Material min. 10 10 Ω) ■ Volume resistance: <10 5 Ω x cm (Standard Material min. 10 12 Ω x cm)
