GF25 Reinforced Polyamide: High-Strength PA66 Material for Demanding Applications

GF25 Reinforced Polyamide denotes a high-performance engineering thermoplastic where the base polyamide resin, commonly Nylon 6 or Nylon 66, is compounded with 25% by weight of short glass fibers. This reinforcement fundamentally transforms the material's properties, creating a composite that offers a superior balance of strength, stiffness, and thermal resistance compared to its unfilled counterpart. The incorporation of glass fibers significantly enhances tensile and flexural strength, while also drastically increasing the material's modulus (stiffness), making components more rigid and dimensionally stable under load. The Heat Deflection Temperature (HDT) is markedly improved, allowing the material to perform reliably in elevated temperature environments, often exceeding 200°C for Nylon 66-GF25. Furthermore, it exhibits reduced creep and superior fatigue endurance compared to unreinforced polyamides. However, this reinforcement introduces anisotropic shrinkage, meaning shrinkage is greater perpendicular to the flow direction than parallel to it, a critical factor that must be accounted for during mold design to prevent warpage. The glass fibers also increase abrasiveness, necessitating the use of wear-resistant materials for processing equipment, such as screws and barrels. Despite the enhanced strength, the presence of fibers can reduce impact strength in some orientations and make the material more notch-sensitive. GF25 Reinforced Polyamide is widely specified in demanding applications across the automotive industry (e.g., engine covers, cooling fans, structural brackets), electrical and electronics sector (connectors, housings), and industrial equipment (gears, bearings, machinery housings) where its excellent mechanical and thermal properties provide significant performance advantages.
