PA6 GF30 Datasheet: Mechanical, Thermal and Processing Properties

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.

乾燥

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.

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:
