描述
VESTAMID LC-GF30 NC is a semi-crystalline, heat- and UV-stabilized polyamide 12 compound from Evonik Operations GmbH reinforced with 30% glass fiber. It is developed primarily for injection-molded connectors and is especially suitable for automotive, mobility, industrial and engineering applications.
Evonik positions the LC-GF family as fiberglass-reinforced PA12 for lightweight, high-performance automotive components. The range is available with several reinforcement levels so engineers can select the required balance between stiffness, strength, flexibility and impact resistance. VESTAMID LC-GF30 NC is the natural-color 30% glass-fiber grade.
The current product information describes VESTAMID LC-GF30 NC as a glass-fiber-reinforced PA12 compound with high strain at break for injection molding. This combination is important for quick connectors. The component must maintain accurate geometry for sealing and locking, but snap-fit tabs and assembly features must also tolerate deformation without brittle failure.
The PA12 matrix absorbs only small amounts of water. As a result, molded parts made from VESTAMID LC-GF30 NC maintain excellent dimensional accuracy when ambient humidity changes. This is a major advantage over more moisture-sensitive polyamides in precision connector applications.
The 30% glass-fiber reinforcement provides high stiffness and strength while the material retains approximately 7% strain at break. Current data lists a tensile modulus of approximately 6,920 MPa and yield stress of approximately 120 MPa, making the grade suitable for highly loaded connector bodies and technical molded parts.
Low-temperature performance is also strong. Charpy impact values remain high at -30°C and -40°C, helping the material perform in automotive environments exposed to severe winter temperatures.
VESTAMID LC-GF30 NC is laser absorbing, electrically insulating, fuel resistant and halogen-free. Current product information also identifies it as lightweight, non-corrosive, semi-crystalline and medium viscosity.

Why Choose VESTAMID LC-GF30 NC?
The main reason to choose VESTAMID LC-GF30 NC is its combination of high stiffness, impact strength and dimensional stability.
Quick connectors are precision parts. Sealing surfaces, locking tabs and snap-fit features must stay within tight tolerances. The 30% glass-fiber reinforcement increases stiffness and reduces shrinkage, helping the connector maintain the intended geometry.
At the same time, the grade retains approximately 7% strain at break. This gives locking and snap-fit features useful deformation capability during assembly and helps avoid overly brittle behavior.
Low water absorption is another important advantage. PA12 absorbs less moisture than many other polyamides, so dimensional and mechanical changes caused by humidity are relatively small.
Low-temperature impact resistance is especially notable. Published unnotched Charpy impact values increase from approximately 98 kJ/m² at 23°C to 102 kJ/m² at -30°C and 106 kJ/m² at -40°C. This supports demanding automotive service in cold climates.
The material is also heat stabilized, UV stabilized, fuel resistant and electrically insulating. For customers who need a natural-color 30% glass-fiber PA12 that can later be colored as required, VESTAMID LC-GF30 NC provides a strong alternative to the ready-black LC-GF30 BK version.
Processing Guidelines for VESTAMID LC-GF30 NC
VESTAMID LC-GF30 NC is designed primarily for injection molding.
The current grade-specific 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 Zone 1 | 260°C |
| Typical Zone 2 | 260°C |
| Typical Zone 3 | 260°C |
| Typical Nozzle Temperature | 260°C |
| Typical Screw Speed | 127 rpm |
| Circumferential Screw Speed | 0.05–0.20 m/s |
| Back Pressure | 0.3–0.8 MPa |
For standardized property testing, the datasheet lists a 260°C melt temperature and 80°C mold temperature for molding-shrinkage specimens.
The material is delivered as cylindrical granules in ready-to-process condition and packed in moisture-tight packaging.
If the original packaging remains intact, additional drying may not be necessary. If the material has absorbed moisture after opening, 80–100°C for 2–4 hours is the current pre-drying recommendation.
The recommended melt-temperature window of 240–280°C and mold-temperature range of 60–100°C should be adjusted according to part geometry, wall thickness, gate design and flow length.
Because VESTAMID LC-GF30 NC contains 30% glass fiber, fiber orientation can influence local stiffness, shrinkage and impact behavior. Gate location and flow direction should therefore be considered carefully during mold design.
VESTAMID LC-GF30 NC vs. VESTAMID LC-GF30 BK
| Feature | VESTAMID LC-GF30 NC | VESTAMID LC-GF30 BK |
|---|---|---|
| Base Polymer | PA12 | PA12 |
| Glass Fiber Content | 30% | 30% |
| Color | Natural | Black |
| Primary Process | Injection Molding | Injection Molding |
| Primary Application | Automotive quick connectors | Automotive quick connectors |
| Heat / UV Stabilization | Yes | Yes |
| Fuel Resistance | Yes | Yes |
| Main Selection Difference | Natural-color base for downstream coloration | Ready-colored black formulation |
| Qualification Rule | Use NC-specific TDS | Use BK-specific TDS |
Choose VESTAMID LC-GF30 NC when a natural-color base material is required for later coloration or a non-black finished component.
Choose VESTAMID LC-GF30 BK when the finished component should be molded directly in black.
