PA66 GF25 pellets (also named Polyamide 66 25% glass fiber granules or Nylon 66 25% glass fiber reinforced resin) is the flagship product of Shuangming Plastic, engineered to address the lightweight, miniaturization and thin-walled design trends in the modern electronics and automotive industries. As a high-performance reinforced engineering plastic, this material is modified with 25% glass fiber, boasting metal-like mechanical properties while featuring a far lower density, making it the optimal solution for metal replacement and "plastic for steel" applications. Our PA66 GF25 pellets are available with OEM custom services, including extrusion grade variants with excellent moldability and fatigue resistance. Produced with renowned raw materials (e.g., Invista/Ascend PA66 resin) and advanced production systems, our products comply with ISO 9001 manufacturing standards, and can meet UL94, RoHS and REACH compliance requirements on request, ensuring reliable quality for global industrial customers.
