What is mPPE PPE-PA?
mPPE PPE-PA is mPPE in the PPE-PA condition — semi-crystalline nylon-continuous alloy chosen when solvent resistance and online-paint-bake temperature are needed (automotive fenders, EV connectors). mPPE PPE-PA has a yield strength of 55 MPa (7.98 ksi) and a tensile strength of 58 MPa (8.41 ksi) — stronger than 62% of polymer grades. Elongation at break is 45% and the elastic modulus is 2.1 GPa (0.305 Msi). mPPE PPE-PA has a density of 1.1 g/cm³ (0.0397 lb/in³), lighter than 66% of polymer grades. Its glass-transition temperature is 145°C (293 °F). UNF is the default condition FabDigit quotes; PPE-PA is available on request or by drawing note.

Working with mPPE PPE-PA
Is mPPE easy to machine?
Machines cleanly with sharp positive-rake tools and air cooling; avoid aromatic/chlorinated coolants which cause stress cracking, and anneal 2 h at ~110 °C before tight-tolerance finishing.
Can mPPE be welded?
Excellent for ultrasonic, vibration and hot-plate welding; solvent bonding with chlorinated solvents or adhesives also works, but hot-gas welding needs careful temperature control to avoid PS-phase degradation.
Can mPPE be formed, bent or molded?
Dry 2–4 h at 100–110 °C, mold at 260–300 °C melt with 60–110 °C tool; amorphous shrinkage of ~0.5–0.7 % is low and isotropic, giving very stable tolerances.
What surface finishes work on mPPE?
Takes paint, hot stamping and electroless plating well after standard etch/primer steps; UV-absorbing paint or pigment is recommended for outdoor use since unstabilized mPPE yellows.
mPPE chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

mPPE PPE-PA — frequently asked
What is mPPE PPE-PA used for?
mPPE PPE-PA is typically used for electrical enclosures and connectors, automotive instrument panels, plumbing fittings, business machine housings and HVAC components. In short: most dimensionally stable amorphous resin; lowest-density engineering thermoplastic; inherently flame-retardant blend.
What is the yield strength of mPPE PPE-PA?
mPPE PPE-PA has a typical yield strength of 55 MPa (7.98 ksi) and a tensile strength of 58 MPa (8.41 ksi) — stronger than 62% of polymer grades. Strength varies by condition: see the 12 listed tempers.
Is mPPE PPE-PA easy to machine?
Reasonably — machinability is rated good (62/100, better than 60% of polymer grades). Machines cleanly with sharp positive-rake tools and air cooling; avoid aromatic/chlorinated coolants which cause stress cracking, and anneal 2 h at ~110 °C before tight-tolerance finishing.
Can mPPE PPE-PA be welded?
Yes — weldability is rated good (60/100). Excellent for ultrasonic, vibration and hot-plate welding; solvent bonding with chlorinated solvents or adhesives also works, but hot-gas welding needs careful temperature control to avoid PS-phase degradation.
What surface finishes work on mPPE PPE-PA?
Takes paint, hot stamping and electroless plating well after standard etch/primer steps; UV-absorbing paint or pigment is recommended for outdoor use since unstabilized mPPE yellows.
Can mPPE PPE-PA be formed, bent or molded?
Dry 2–4 h at 100–110 °C, mold at 260–300 °C melt with 60–110 °C tool; amorphous shrinkage of ~0.5–0.7 % is low and isotropic, giving very stable tolerances.
What is the maximum service temperature of mPPE PPE-PA?
mPPE PPE-PA is rated for continuous use to about 110°C (230 °F), and briefly to 130°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between mPPE UNF and mPPE SF?
UNF is the default condition — default choice for housings, water-contact parts and dielectric components needing toughness and dimensional stability. SF: chemically blown thick-wall grade for large, stiff, low-density enclosures and pallets. Yield strength is 58 MPa in UNF versus 32 MPa in SF.
