GF25 Reinforced Nylon Granules for High-Performance Extrusion

GF25 Reinforced Nylon Granules are the physical form of this composite material, supplied as small, free-flowing pellets ready for processing in injection molding or extrusion machines. The granule form is critical for ensuring consistent and reliable handling in automated feeding systems. The compounding process to create these granules involves meticulously mixing the base nylon polymer with precisely 25% by weight of short, chopped glass fibers in a twin-screw extruder. This process ensures the fibers are evenly distributed and well-wetted by the polymer matrix, which is essential for achieving uniform mechanical properties in the final product. The molten composite is then strand-pelletized into granules of a specific size and shape to promote smooth flow. The quality of these granules is paramount; it directly influences processing stability and final part performance. Key quality metrics include consistent glass fiber content and length distribution, low moisture levels (as nylon is highly hygroscopic), and the absence of contaminants. Upon receipt, these granules must be properly dried in a dehumidifying hopper dryer to reduce moisture content to below 0.2% (or lower for critical applications) before processing, as residual moisture can cause hydrolysis, leading to molecular weight degradation and a severe loss of mechanical properties during melting. When processed correctly, GF25 Reinforced Nylon Granules yield parts with a superior surface finish, excellent mechanical strength, and high dimensional stability, making them a preferred material choice for engineers designing high-performance, lightweight components.
