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.

Thermal property ranges for PA6 GF30. The CTE (coefficient of thermal expansion) is significantly anisotropic — expansion in the transverse (normal) direction is 2-4x higher than in the flow (parallel) direction due to glass fiber orientation.

Electrical properties for standard PA6 GF30. Note: values assume dry conditioning. Moisture absorption significantly impacts electrical properties — dielectric constant and dissipation factor increase, while volume resistivity decreases by 1-2 orders of magnitude at equilibrium moisture content.

Physical properties. Note the 3:1 to 4:1 ratio between normal and parallel shrinkage — this anisotropy is the primary cause of warpage in glass-fiber-reinforced parts and must be accounted for in mold design.

Flammability

Flammability properties. Standard PA6 GF30 is not self-extinguishing. For applications requiring UL 94 V-0, V-1, or V-2, a flame-retardant grade (PA6 GF30 FR) must be specified.

Processing Parameters

التجفيف

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.

Injection molding parameter ranges for PA6 GF30. These are starting-point recommendations; actual parameters depend on part geometry, gate design, and machine characteristics.

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:

الممتلكاتDry (as molded)Conditioned (50% RH, 23 C)Change
قوة الشد (ميجا باسكال)180110-130-30 to -40%
معامل الانثناء (جيجا باسكال)9.06.0-7.0-25 to -35%
Charpy Notched Impact (kJ/m2)1420-28+50 to +100%
HDT at 1.8 MPa (C)20065-75 (wet)Significant drop at full saturation
Approximate mechanical property shift from dry to conditioned state. Design calculations should use conditioned values if the part operates in ambient humidity. Dry values apply to parts sealed against moisture or used in very dry environments.
