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.

Verwerkingsparameters
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 |

PA6 Glass Fiber Grade Comparison: GF15 vs GF30 vs GF40 vs GF50
Glass fiber content drives the performance-cost trade-off in PA6 compounds. The table below shows how increasing glass fiber from 15% to 50% changes key mechanical and thermal properties. Use these screening values to narrow your grade selection before requesting commercial datasheets.

| Typische toepassingen | Non-structural clips, covers | Housings, brackets, medium stiffness | Engine covers, fan shrouds, power tool housings | High-stiffness frames, pump bodies | Metal replacement, extreme rigidity |
Selection guidance: PA6 GF30 is the most commonly specified glass-filled PA6 grade because it delivers the best stiffness-to-cost ratio for typical structural applications. Move to GF40 or GF50 only when the application demands stiffness approaching aluminum or when wall thickness is constrained. Stay with GF15 when flow into thin-wall features or impact toughness at low temperature matters more than maximum rigidity.

When substituting between PA6 GF30 suppliers, compare full datasheets in the same conditioned state (dry-as-molded vs 50% RH), verify mold shrinkage in both flow and transverse directions, and run a production-tool trial. Even nominally equivalent PA6 GF30 grades differ in fiber length retention, color stability, heat aging, and processing window.
Veelgestelde vragenWhat 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.
