Examid® PPA/PA66 GF50 Y is a heat-stabilized semi-aromatic blend (PPA + PA66) with 50% glass fiber. The line’s flagship overall: flexural strength of 380 MPa, tensile modulus of 18,000 MPa, HDT of 285 °C at 1.8 MPa, melting at 325 °C.

Flow shrinkage of 0.1% is precision-level. The electrical package is complete: CTI of 600 V, dielectric strength of 30 kV/mm, volume resistivity of 10¹¹ Ω·m — the material qualifies for power electronics and high-voltage connectors, including e-mobility.

Cold performance: Izod unnotched 80 kJ/m² at −30 °C. Part service range — from −30 to +200 °C with retained stiffness. Processing: melt 325–340 °C, mold 140 °C. The position covers Ultramid® Advanced / Grivory HT GF50-class applications at a substantial price advantage.

Examid® PPA/PA66 GF30 Y is a semi-aromatic polyamide blend (PPA + PA66) with 30% glass fiber. An engineering compromise: heat resistance close to neat PPA (HDT of 275 °C at 1.8 MPa, melting at 310 °C) with processing simpler and cheaper than full polyphthalamide.

Mechanics exceed standard PA66 GF30: tensile strength of 210 MPa (vs 180), flexural strength of 280 MPa, modulus of 10,000–10,500 MPa. Izod impact of 75 kJ/m² unnotched, 13 kJ/m² notched.

Positioning: parts where PA66 GF30 falls short on temperature but full PPA is cost-excessive — engine-zone housings, E&E components, structural elements serving up to 180–200 °C. Processing: melt 320–335 °C, mold 100–140 °C — milder than neat PPA (135–165 °C). Up to 25% regrind.

Examid® PPA GF40 is a polyphthalamide reinforced with 40% glass fiber. The semi-aromatic matrix places the material in the high-temperature class: melting point of 310 °C, HDT of 275 °C at 1.80 MPa — a range inaccessible to aliphatic PA66 GF.

PPA’s second advantage is moisture uptake of 0.9% (23 °C, 50% RH), 2.5–3× lower than PA66: mechanics and dimensions stay stable in humid environments. Tensile modulus of 13,500 MPa, strength of 155 MPa, Charpy unnotched impact of 100 kJ/m². Dielectric strength of 27 kV/mm supports E&E service.

The niche: connectors and power-electronics housings, engine-zone parts, metal and PPS replacement in hot humid assemblies. Class analogs — Ultramid® Advanced N GF, Grivory® HTV. Processing: melt 320–335 °C, mold 135–165 °C — hot mold temperature control required.

Examid® PPA GF40 HSL — a structural polyphthalamide (PA6T/6I copolymer) with 40 % short glass fiber and a comprehensive modification package designated by the HSL suffix.

What the HSL suffix means

In the practice of global PPA manufacturers (Solvay Amodel, DuPont Zytel HTN, Toray Siveras, BASF Ultramid Advanced), the HSL suffix stands for HSL = Heat-Stabilized + Lubricated:

• HS — Heat Stabilized: improved resistance to thermal aging during long-term service at 150–200 °C, minimal loss of mechanical properties after 1000–3000 h in hot air or hot liquids.
• L — Lubricated: an internal package of processing lubricants (PE waxes, montan esters) for improved flow, shorter molding cycles and better surface detail reproduction on thin-walled and complex parts.

Within the Examid PPA family, the HSL series covers the GF33 and GF40 grades (everyday structural applications); the HLS series covers GF50 (higher reinforcement).

How Examid® PPA GF40 HSL differs from standard PA66 GF40

• Melting temperature ~310–325 °C versus ~260 °C for PA66 — real-world service at 170–200 °C under load, short-term up to 230 °C.
• Modulus stability under moisture absorption: PPA loses ~15 % of its modulus at moisture saturation, PA66 GF40 up to 50 %.
• HDT/A (1.8 MPa) ~290–305 °C — close to the melting point, unlike PA66 GF40 (~245 °C).
• Dimensional stability during lead-free reflow soldering (up to 260 °C, 30 s) without softening.

Advantages

• High strength and stiffness over a wide range of temperatures and humidity
• Dimensional stability under reflow soldering and in hot liquid media
• Creep resistance under sustained load at 120–180 °C
• Low moisture absorption and stable electrical properties in connectors
• High flow thanks to the L package — filling of thin 0.5–0.8 mm walls
• Resistance to glycols, oils, antifreezes, weak acids, aromatic fuels
• Fast molding cycle in water-heated molds at 140–160 °C (no oil heating system required)

Limitations — honestly

• High processing temperature (melt 320–340 °C) — requires a hot-runner system and corrosion-resistant components on the molding machine
• Moisture-sensitive before processing — mandatory drying at 120 °C for 4–8 h down to <0.08 %
• Cost 3–5 times higher than PA66 GF — justified where PA66 objectively cannot perform
• The base grade is rated UL 94 HB — separate FR grades are needed for V-0/V-2 applications
• Brittle failure is possible under high local loads — design for creep resistance, not impact energy
• Dark natural color (beige-brown) — pigmentation is possible, but the color palette is limited

Target applications

Automotive: turbo ducts, resonator housings, EGR components, thermostats, oil pump housings, EV high-voltage system connectors, ignition coil holders.

Electronics and electrical engineering: SMT connectors for lead-free reflow, relay housings, power module insulators, switch contact assemblies, 5G/mmWave antenna platforms.

Industry: hot-liquid pump housings, in-line flow sensors, fittings for heating systems and heat exchangers, components of high-power LED luminaires.

Household appliances: coffee machine parts (contact with hot water and steam), dishwasher assemblies, professional-grade blender housings.
