Working with PPE-GF30
Is PPE-GF30 easy to machine?
Machines cleanly but the 30% glass is abrasive — use sharp carbide or PCD tools, high speed/low feed, air or mist cooling, and avoid aggressive coolants that can stress-crack the PPE.
Can PPE-GF30 be welded?
Ultrasonic, vibration and hot-plate welding all work well (amorphous, no sharp Tm); solvent bonding with chlorinated solvents is possible but risks stress cracking, and weld/knit lines lose most of the fiber reinforcement.
Can PPE-GF30 be formed, bent or molded?
Injection mold at 270–310 °C melt / 80–110 °C tool with pre-drying 2–4 h at 100–110 °C; use generous gates and hardened, wear-resistant tool steel because of glass abrasion, and expect anisotropic 0.1–0.4 % shrink with warpage in thin flat parts.
PPE-GF30 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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| poly(2,6-dimethyl-1,4-phenylene ether) (base resin of the modified PPE blend | 35 – 60 | 45 |
| polystyrene / HIPSmiscible modifier setting Tg and flow | 8 – 30 | 22 |

| impact modifier (SBS/SEBS)grade dependent | 0 – 8 | 2 |
| stabilizers, pigments, processing aids | 0.5 – 3 | 1 |
What surface finishes work on PPE-GF30?
Paints and adhesives bond well after light abrasion or plasma/flame treatment (no primer needed for many 2K PU systems); glass read-through limits high-gloss appearance, and PPE is a classic substrate for electroless plating pretreatment.

PPE-GF30 — frequently asked
What is PPE-GF30 used for?
PPE-GF30 is typically used for automotive body panels and mirror housings, structural electrical components, pump housings and under-hood brackets. In short: stiffest PPE grade; low-warp glass-filled amorphous; online-paintable body panels.
What is the tensile strength of PPE-GF30?
PPE-GF30 has a typical tensile strength of 120 MPa (17.4 ksi) — stronger than 93% of polymer grades. Strength varies by condition: see the 10 listed tempers.
Is PPE-GF30 easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Machines cleanly but the 30% glass is abrasive — use sharp carbide or PCD tools, high speed/low feed, air or mist cooling, and avoid aggressive coolants that can stress-crack the PPE.
Can PPE-GF30 be welded?
With care — weldability is rated fair (45/100). Ultrasonic, vibration and hot-plate welding all work well (amorphous, no sharp Tm); solvent bonding with chlorinated solvents is possible but risks stress cracking, and weld/knit lines lose most of the fiber reinforcement.
What surface finishes work on PPE-GF30?

What is the maximum service temperature of PPE-GF30?
PPE-GF30 is rated for continuous use to about 110°C (230 °F), and briefly to 145°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
