Advantages: Light-weight, typically 4.6 pounds/1000 feet (6.8 kg/km)
Good abrasion and cut-through resistance
Passes standard low temperature flame tests
Excellent physical thermal and electric properties
Excellent radiation resistance (to 5 x10^9 Rd)
Excellent out-gassing characteristics
Very high temperature rating of 260o C with nickel coated copper conductor
Disadvantages: Aging lowers flexibility
Susceptible to hydrolysis at high temperature and strain
Prone to wet and dry arc tracking
Fails by Radial cracks and delamination (unwrapping)
Attacked by strong acids and bases
Other Information: The PMDA-ODA film itself can have an FEP adhesive on either side. In addition, there maybe an FEP film. This should not be confused with the topcoat on finished wires
Wires using PMDA-ODA insulation have different topcoats depending on whether they are manufactured to USA Military, US civilian or European specifications
The PANAVIA standard (Europe) has a FEP lacquer as the topcoat (PAN 6423) or a PTFE topcoat (PAN 6411) – see the TKT page also
EL 2124 and EL 3001 have a FEP lacquer as the topcoat) – see the TKT page also
ACT 150 and ACT 260 have a PTFE topcoat) – see the TKT page also
DSP33/08 has a UV laser markable PTFE Tape) – see the TKT page also
The Military Standard in the United States has a modified aromatic poly imide resin as the topcoat
Wires using PMDA-ODA insulation can have poly imide tapes of different thickness: this is clearly indicated in the specification data sheets, for example, MIL-W-81381/7 has a thinner inner tape than MIL-W-81381/11
PMDA-ODA topcoat on MIL-W-22759/28 to /31 and MIL-W-81822/4
PMDA-ODA is a component for MIL-W-25038/1 to /3
Poly amide (Nylon is in this class of compounds) braid used on some larger diameter MIL-W-81381 wire (usually gauge 8 or larger) – see specification data sheets for details
With some versions of DSP33/08 the first layer has a “fluorocarbon polymer tape”
JN1007 wire has an added inner layer between the PMDA-ODA tape and the conductors – at least one specification sheet has a PTFE inner tape) – see the TKT page also
EFA 200 and MDS 4480 have an inner PTFE tape with PMDA-ODA and either a FEP or PTFE topcoat) – see the TKT page also
PMDA-ODA top coat with Poly-X (Raychem patent)
PVDF has been reported to be used as a top coat with some PMDA-ODA insulated wires
Pyre-ML® is applied as a coating of PMDA-ODA on wiring.
