描述
VESTAMID LC-GF30 BK is a semi-crystalline, heat- and UV-stabilized polyamide 12 compound from Evonik Operations GmbH reinforced with 30% glass fiber. It is designed 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 series is available in several reinforcement levels so designers can choose the required balance between stiffness, strength, impact resistance and flexibility. VESTAMID LC-GF30 BK is the black 30% glass-fiber grade in this portfolio.
The current product information describes VESTAMID LC-GF30 BK as a glass-fiber-reinforced PA12 compound with high strain at break for injection molding. This is important because quick connectors require more than stiffness alone. Locking features, clips and assembly elements need to tolerate deformation without becoming excessively brittle.
The PA12 matrix absorbs only small amounts of water. Components molded from VESTAMID LC-GF30 BK therefore maintain excellent dimensional accuracy when ambient humidity changes. This is particularly important for precision connector housings and fluid-system parts where sealing surfaces and locking dimensions must remain consistent.
The 30% glass-fiber reinforcement provides substantially higher stiffness and strength than lower-reinforcement LC-GF grades. Published data shows a tensile modulus of approximately 7,150 MPa and yield stress of approximately 126 MPa, while the material still retains approximately 7% strain at break.
Low-temperature impact performance is another important advantage. The grade maintains high unnotched Charpy impact strength at -30°C and -40°C, making it suitable for automotive applications exposed to winter conditions.
VESTAMID LC-GF30 BK is black, laser absorbing, electrically insulating and fuel resistant. Current grade information also identifies it as halogen-free, semi-crystalline, UV stabilized, lightweight and non-corrosive.

Why Choose VESTAMID LC-GF30 BK?
The main reason to choose VESTAMID LC-GF30 BK is its combination of high stiffness, dimensional stability and impact strength.
Quick connectors are highly geometry-dependent parts. Sealing surfaces, locking tabs and snap-fit features must remain within tight dimensional tolerances. The 30% glass-fiber reinforcement increases stiffness and reduces molding shrinkage, helping the connector retain its intended geometry.
At the same time, the grade retains approximately 7% strain at break. This is useful for connector features that must flex during assembly and reduces the risk of excessively brittle behavior compared with materials that prioritize stiffness alone.
The low water absorption of PA12 provides another important advantage. Mechanical properties and dimensions remain relatively stable under changing humidity, supporting more predictable performance in real automotive environments.
Low-temperature impact resistance is especially strong. The unnotched Charpy impact value actually remains around 100 kJ/m² or above at -30°C and -40°C, which is valuable for components exposed to winter service.
The material is also heat stabilized, UV stabilized, fuel resistant and electrically insulating. These characteristics make VESTAMID LC-GF30 BK a strong choice for automotive quick connectors, fluid-system housings and other high-load molded PA12 components.
Processing Guidelines for VESTAMID LC-GF30 BK
VESTAMID LC-GF30 BK 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 Zone 1 | 260°C |
| Typical Zone 2 | 255°C |
| Typical Zone 3 | 250°C |
| Typical Nozzle Temperature | 255°C |
| Typical Screw Speed | 127 rpm |
| Circumferential Screw Speed | 0.05–0.20 m/s |
| Back Pressure | 0.3–0.8 MPa |
| Typical Holding Pressure | 8 MPa |
The material is supplied 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, the published 80–100°C for 2–4 hours drying recommendation 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, wall thickness, gate design and flow length.
Because VESTAMID LC-GF30 BK contains 30% glass fiber, fiber orientation can influence stiffness, shrinkage and local impact performance. Gate position and flow direction should therefore be considered carefully when designing quick-connector molds.
