描述
VESTAMID LC-GF15 NC is a semi-crystalline, heat- and UV-stabilized polyamide 12 compound from Evonik Operations GmbH reinforced with 15% glass fiber. It was developed primarily for injection-molded connectors and is especially suitable for automotive and mobility applications.
Evonik positions the LC-GF family as fiberglass-reinforced PA12 for high-quality lightweight automotive components. The family is available with different glass-fiber contents, allowing designers to choose a balance between stiffness, strength and flexibility. VESTAMID LC-GF15 NC is the 15% glass-fiber, natural-color grade in this portfolio.
A major design objective of VESTAMID LC-GF15 NC is to combine reinforcement with comparatively high strain at break. The current product information describes it as a glass-fiber-reinforced PA12 compound with high strain at break for injection molding. This makes it particularly attractive for quick connectors and other components that need more rigidity than unfilled PA12 without sacrificing all of the ductility and impact behavior associated with PA12.
The semi-crystalline PA12 base absorbs only small amounts of water. Because of this, molded components maintain good dimensional accuracy when ambient humidity changes. This is important for quick connectors, clips, housings and other precision parts where dimensional variation can affect fit, sealing or assembly.
The 15% glass-fiber reinforcement increases stiffness and thermal load capacity while keeping the material lighter than metal alternatives. Evonik also highlights the potential to reduce wall thickness in components, which can contribute to lower component weight and manufacturing cost.
VESTAMID LC-GF15 NC is heat stabilized and UV/light/weathering stabilized. The current product information also identifies the grade as fuel resistant, electrically insulating and laser absorbing.

Why Choose VESTAMID LC-GF15 NC?
One of the main reasons to choose VESTAMID LC-GF15 NC is its balance of stiffness and ductility.
Increasing glass-fiber content generally increases rigidity, but it can also reduce flexibility. The LC-GF family gives engineers multiple reinforcement levels so that a grade can be selected according to the required strength-versus-flexibility balance.
At 15% glass fiber, VESTAMID LC-GF15 NC offers significantly higher stiffness than unfilled PA12 while retaining an 8% strain at break and strong impact behavior. This can be especially valuable for quick connectors that need to tolerate assembly forces, clips, locking features and vibration.
Another major advantage is dimensional stability. PA12 absorbs relatively little moisture, so dimensional and mechanical properties vary less with humidity than many other engineering polyamides. In connector applications, this can help maintain sealing geometry and assembly tolerances.
The material also provides corrosion resistance compared with metal and can reduce component weight. Evonik highlights metal replacement as an important benefit of LC-GF PA12 in automotive quick connectors.
Finally, the high HDT, fuel resistance and UV stabilization make the grade useful in demanding automotive environments where the component may be exposed to temperature variation, fuel-related media and environmental aging.
Processing Guidelines for VESTAMID LC-GF15 NC
VESTAMID LC-GF15 NC is designed primarily for injection molding.
The current product information gives the following processing recommendations:
| Processing Parameter | Recommended Range / Value |
|---|---|
| Pre-Drying Temperature | 80–100°C |
| Pre-Drying Time | 2–4 hours |
| Target Processing Moisture | ≤0.1% |
| Melt Temperature | 240–280°C |
| Mold Temperature | 60–100°C |
| Feed Temperature | 40–60°C |
| Typical Nozzle Temperature | Approx. 250°C |
| Typical Screw Speed | Approx. 127 rpm |
| Circumferential Screw Speed | Approx. 0.05–0.20 m/s |
| Back Pressure | Approx. 0.3–0.8 MPa |
| Typical Holding Pressure | Approx. 6 MPa |
The grade is supplied as cylindrical granules in a ready-to-process condition and packed in moisture-tight packaging. If original packaging remains intact, unnecessary drying should be avoided. If the material has absorbed moisture after the package has been opened, the published pre-drying range provides a suitable starting point.
The recommended melt-temperature window of 240–280°C and mold-temperature range of 60–100°C should be adjusted according to part geometry, flow length, gate design and required surface quality.
Because VESTAMID LC-GF15 NC contains glass fiber, mold and gate design should account for fiber orientation. Flow direction can influence local mechanical behavior, so critical connector features should be evaluated under realistic molding conditions.
