When you need PA6 GF30 property data, you are usually not looking for a narrative guide. You need numbers — tensile strength, flexural modulus, HDT, shrinkage — in one place, with the test standards cited so you can compare grades from different suppliers without translation errors. This page is that reference. It covers the standard property set for a heat-stabilized PA6 with 30% glass fiber reinforcement, the test methods behind each number, and the processing windows that matter to molders.

Processing Parameters
Drogen
PA6 GF30 must be dried to a moisture content below 0.10% (target 0.05%) before injection molding. Recommended drying: 80 C for 4-6 hours in a desiccant dryer with a dew point of -30 C or lower. Tray drying at 80 C for 8-12 hours is acceptable for non-critical applications but is less reliable than desiccant drying. Do not dry above 90 C — oxidative discoloration (yellowing) begins at higher temperatures.
Spuitgieten
| Parameter | Recommended Range | Opmerkingen |
|---|---|---|
| Melt Temperature (nozzle) | 250-280 C | Lower end for thin walls, upper for thick |
| Schimmel Temperatuur | 80-100 C | 100 C preferred for crystallinity and surface |
| Injectiesnelheid | Gemiddeld tot snel | Faster fill reduces fiber orientation variation |
| Hold Pressure | 50-80% of injection pressure | Enough to pack out shrinkage, avoid overpacking |
| Tegen druk | 5-15 bar (hydraulic) | Higher back pressure improves melt homogeneity |
| Schroefsnelheid | 50-150 rpm | Lower end for larger shot sizes to avoid shear heating |
| Residence Time (max at melt temp) | 10-15 minutes | Purge if longer; degraded PA6 produces burn marks and strength loss |
Mold Design Considerations
- Gate type: All standard gate types are suitable. Pin gates, edge gates, and fan gates all work. Tunnel (submarine) gates require attention to gate diameter — minimum 0.8 mm to avoid excessive shear with 30% GF.
- Gate location: Position the gate so flow is into the thickest section. Avoid long flow paths that allow the melt front to cool before the cavity fills.
- Venting: Adequate venting is critical. Poor venting leads to burn marks, short shots, and die buildup. Vent depth: 0.01-0.02 mm.
- Draft angle: Minimum 1 degree, 2 degrees preferred for textured surfaces. GF grades shrink tightly onto cores — adequate draft prevents ejection damage.
- Steel selection: 30% glass fiber is abrasive. For production runs exceeding 100,000 shots, use hardened tool steel (min. 52 HRC) for cavities and cores, especially at gates and high-wear areas.
Property Changes with Moisture Conditioning
PA6 absorbs moisture from the environment. At equilibrium with 50% RH at 23 C, a PA6 GF30 part will absorb approximately 1.5-2.0% water by weight. This changes the mechanical properties significantly. Tensile strength decreases by 30-40%, flexural modulus by 25-35%, and impact strength increases by 50-100%. The data table below shows the approximate shift from dry-as-molded to conditioned (50% RH) values:
| Eigendom | Dry (as molded) | Conditioned (50% RH, 23 C) | Change |
|---|---|---|---|
| Treksterkte (MPa) | 180 | 110-130 | -30 to -40% |
| Flexural Modulus (GPa) | 9.0 | 6.0-7.0 | -25 to -35% |
| Charpy Notched Impact (kJ/m2) | 14 | 20-28 | +50 to +100% |
| HDT at 1.8 MPa (C) | 200 | 65-75 (wet) | Significant drop at full saturation |

Veelgestelde vragen
What are the key properties to check in a PA6-GF30 datasheet?
Focus on tensile strength (typically 170-190 MPa), flexural modulus (7,000-9,000 MPa), notched Izod impact (10-15 kJ/m²), HDT at 1.8 MPa (195-215°C), density (1.35-1.38 g/cm³), mold shrinkage (0.2-0.5%), and melt flow rate.
Why does PA6-GF30 datasheet strength vary between suppliers?
Variations come from differences in glass fiber type (E-glass vs. others), fiber length distribution, coupling agent quality, and base resin molecular weight. A datasheet showing ±5% deviation from these ranges is within industry norms.
How should I read PA6-GF30 datasheet values for my design?
Use “conditioned” values (tested at 23°C/50% RH equilibrium) for parts operating in ambient environments, and “dry-as-molded” values for parts in dry or sealed applications. Safety factors of 1.5-2.5× should be applied to datasheet ultimate properties for design calculations.
What processing parameters does a good PA6-GF30 datasheet include?
A complete datasheet should specify melt temperature (260-280°C), mold temperature (80-100°C), drying conditions (80°C/4-6h to <0.15% moisture), injection speed (medium-high), and recommended back pressure (0.3-0.7 MPa) to prevent fiber degradation.
