Product Introduction and Application Fields of Reinforced PA6 GF30 Golden Yellow
【Product Introduction】
Reinforced PA6 GF30 Golden Yellow is a high-performance engineering plastic modified with 30% glass fiber reinforcement, based on polycaprolactam (PA6). With its unique golden yellow appearance and excellent comprehensive performance, it has significant adaptability advantages in high-end manufacturing fields. Its core highlights focus on three key dimensions:
Outstanding reinforcement modification advantages: 30% glass fiber is uniformly dispersed in the base material, greatly improving the material's rigidity, strength, and dimensional stability, effectively overcoming the defects of pure PA6 such as easy water absorption and creep. The attenuation rate of mechanical properties after long-term use is ≤ 8%.
Excellent appearance and processing characteristics: It presents a uniform golden yellow color with high surface finish (Ra ≤ 0.8μm). It combines the good molding fluidity of PA6 and the molding stability of glass fiber reinforced materials, and can be adapted to the processing of complex structural parts.
Prominent environmental adaptability: It has excellent oil resistance and chemical corrosion resistance (resistant to most organic solvents, weak acids and weak bases), a long-term service temperature range of -40℃ ~ 120℃, and good electrical insulation and wear resistance, meeting the harsh use requirements of multiple scenarios.

Surface Finish | ISO 4287 | μm | Ra≤0.8 |
Water Absorption (24h, 23℃) | ISO 62 | % | ≤1.5 |
Notes: 1. Heat Distortion Temperature (1.8MPa): Refers to the temperature at which the material starts to deform under 1.8MPa pressure, directly reflecting the material's high-temperature resistance; 2. Water Absorption (24h, 23℃): Refers to the water absorption ratio of the material soaked in 23℃ environment for 24 hours. PA6 base material is easy to absorb water, and this parameter can guide the adjustment of drying process before processing.

【Injection Molding Processing Suggestions Table】
Processing Link | Specific Parameter Requirements | Core Function |
|---|---|---|
Raw Material Drying | Drying temperature 80-100℃, drying time 3-4 hours, residual moisture content ≤ 0.1% | Avoid silver streaks and bubbles in products, reduce the impact of water absorption on mechanical properties |
Processing Temperature | Barrel temperature: front section 230-240℃, middle section 240-250℃, rear section 220-230℃; nozzle temperature 250-260℃ | Ensure good fluidity of the melt, avoid material degradation or darkening due to excessive temperature |
Mold Temperature | Conventional 40-60℃; 60-80℃ for complex structural parts | Improve the smoothness of melt filling, reduce internal stress, and ensure uniform golden yellow appearance of products |
Injection Parameters | Injection pressure 100-150MPa (adjust as needed); injection speed: medium-speed uniform (avoid uneven glass fiber orientation); holding pressure 40%-60% of injection pressure, holding time 2-4 seconds | Avoid flash and glass fiber exposure, ensure dense products, and guarantee appearance and mechanical properties |
Screw Speed and Back Pressure | Screw speed 40-60r/min, back pressure 10-15MPa | Improve the uniformity of melt plasticization, ensure uniform dispersion of glass fiber, and avoid glass fiber breakage due to excessive rotation speed |
Post-processing | Annealing treatment at 70-80℃ for 1-2 hours | Eliminate internal stress, improve dimensional stability, and reduce deformation caused by water absorption during use |
Other Precautions | Prefer hot runner molds; ensure sufficient mold ventilation; clean the barrel and nozzle in time after processing (avoid scratches on the barrel caused by residual glass fiber) | Prevent gas trapping and material shortage, extend the service life of equipment, and ensure the consistency of subseque |
