What is PA6-3-T GF30?
PA6-3-T GF30 is PA6-3-T in the GF30 grade — choose only when stiffness, creep resistance and dimensional stability at temperature matter more than transparency, which is lost entirely. PA6-3-T GF30 has a yield strength of 78 MPa (11.3 ksi) and a tensile strength of 150 MPa (21.8 ksi) — stronger than 86% of polymer grades. Elongation at break is 3% and the elastic modulus is 8.5 GPa (1.23 Msi). PA6-3-T GF30 has a density of 1.35 g/cm³ (0.0488 lb/in³), heavier than 75% of polymer grades. Its glass-transition temperature is 150°C (302 °F).

Working with PA6-3-T GF30
Is PA6-3-T easy to machine?
Machines cleanly with sharp positive-rake tools, high speed and low feed; use air or mist cooling and anneal (~120 °C) before finishing to avoid stress crazing in clear parts.
Can PA6-3-T be welded?
Joinable by ultrasonic, hot-plate, vibration and laser welding; solvent bonding is possible but risks stress cracking — prefer adhesive or welded joints on stressed clear parts.
Can PA6-3-T be formed, bent or molded?
Dry pellets to <0.05 % moisture (80 °C, 4–6 h), melt 250–290 °C, mold 60–110 °C; hot molds and low shear give best clarity, and shrinkage is low and isotropic because the polymer is amorphous.
What surface finishes work on PA6-3-T?
Takes optical polishing, hard/anti-fog coatings and pad printing well; avoid alcohol-based cleaners and solvent-heavy paints on stressed surfaces.
PA6-3-T chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

|---|---|---|
| trimethylhexamethylenediamine (2,2,4-/2,diamine component, mol% of repeat unit | 48 – 52 | 50 |
| terephthalic aciddiacid component, mol% of repeat unit | 48 – 52 | 50 |
