UL 1659 PTFE Wire Supplier — 250°C 600V Fluoropolymer Hook-Up from China to Germany

UL AWM Style 1659 is a single conductor with extruded PTFE/TFE insulation, rated 250°C and 600 Vac, covering 26 AWG to 4/0 AWG in solid or stranded round construction for internal wiring. A mica tape wrap and a treated glass braid are available as optional constructions, and Oil Resistant 80°C and Gasoline Resistant are optional ratings available only by confirmed construction. This page covers supply and sourcing for German buyers. Conductor material, plating, detailed stranding, marking, packaging, shipment terms and documentation are confirmed by quotation.

This page covers UL AWM Style 1659 PTFE wire supply for German buyers, and is organised around what needs to be settled before a quotation can be issued. UL Style 1659 is a single conductor with extruded insulation, rated 250°C and 600 Vac, covering 26 AWG to 4/0 AWG in solid or stranded round construction. The insulation material is PTFE/TFE and the stated use is internal wiring.

Because the Style file fixes only a limited set of parameters, most of a UL 1659 order is defined by the specification the buyer supplies rather than by the Style itself. The sections below set out which items are fixed, which are open to the order, and what to confirm before production begins. For the general product page, see UL 1659 PTFE wire for 250°C 600V internal wiring.

Order Requirements for German Buyers

The table below sets out the items that define a UL 1659 order. None of these is fixed by the Style file — each is established through the quotation and the approved order specification.

Order itemStatus
AWGWithin the Style range of 26 AWG – 4/0 AWG; specify at enquiry
Solid or stranded requirementBoth within the Style scope; specify at enquiry
Requested conductor material and platingNot defined at Style level; confirmed for the ordered construction
Detailed strandingConfirmed in the approved order specification or datasheet
Required finished outside diameterConfirmed in the approved order specification or datasheet
ColourSpecify at enquiry; confirmed against production capability
MarkingConfirmed within the applicable certified scope before production
Reel lengthSpecify at enquiry; confirmed in the quotation
PackagingSpecify at enquiry; confirmed in the quotation
Required documentsSpecify at enquiry; availability confirmed for the ordered construction

Conductor resistance, strand construction and finished dimensions are set out in the approved order specification or datasheet for the construction being supplied, rather than published as fixed catalogue figures.

Optional Ratings and Coverings

Four elements listed in the Style file are optional rather than standard: the mica tape wrap, the treated glass braid, the Oil Resistant 80°C rating and the Gasoline Resistant rating.

Each must be requested separately at enquiry — specifying one does not carry any of the others, and none is applied by default. The optional coverings do not change the Style temperature rating or extend the stated use beyond internal wiring. Where any optional element is required, the ordered construction, the covering or rating actually applied, the product marking and any supporting documents must all be confirmed for the ordered product before production.

Information to Confirm with the Supplier

For a German buyer setting up a first UL 1659 order, the following items are worth settling explicitly in writing rather than assuming:

  • The applicable UL Style being supplied
  • AWG and whether solid or stranded construction is required
  • Requested conductor material and plating
  • Which insulation-thickness group applies to the specified AWG
  • Whether an optional mica tape wrap or treated glass braid is required
  • Whether an optional Oil Resistant 80°C or Gasoline Resistant rating is required
  • The actual marking to be applied to the wire
  • Whether samples are required before the production order
  • The approved datasheet for the construction being supplied
  • Packaging format and reel or cut length
  • Batch identification, if your incoming inspection process requires it
  • Required commercial, compliance and import documents
  • Final destination and requested Incoterm

Settling these at quotation stage avoids the situation where a construction is produced against an assumption rather than against a confirmed specification.

UL Marking and Required Documentation

The ordered construction, the applicable certified scope, any optional rating specified, the actual UL marking applied and the supporting documents must all be confirmed before production. Only products bearing the applicable UL Mark should be represented as covered products.

Where UL, RoHS, REACH, oil-resistance, gasoline-resistance, batch or import documents are required for your process, specify them during enquiry so availability can be confirmed for the ordered construction rather than assumed.

Shipping and Packaging Requirements

Shipment arrangements are set per order. To prepare a quotation, confirm the final destination, the requested Incoterm, the transport method, the quantity, the reel or cut length, the packaging format, the delivery schedule, the marking, and the commercial, import and compliance documents required at the destination.

Minimum order quantity, sample availability, stock position, price, shipment terms and delivery schedule are all confirmed in the quotation rather than fixed in advance.
