Axial, cross-flow, and centrifugal fan blades are the core air-delivery components of modern air conditioning systems
To resolve these demanding engineering challenges, Qingdao Zhongxin Huamei Plastic Co., Ltd.supplies specialized Glass Fiber Reinforced AS (SAN) resin, serving as a reliable material solution for home appliance OEMs
Key Mechanical, Thermal & Acoustic Advantages for HVAC Fan Blades
Our engineered GF-AS compound optimizes the base matrix through glass fiber reinforcement, delivering high structural rigidity and smooth airflow
[Continuous High-Speed Rotation] ➔ [Glass Fiber AS Matrix] ➔ [Dynamic Balance (HDT 102–103°C)] ➔ [Low-Noise, Smooth Airflow]
Stable Dynamic Balance & Low-Noise Delivery: High thermal stability allows molded fan blades to maintain precise dynamic balance even during high-heat heating cycles
. This suppresses rotational vibration and minimizes operational noise . High Strength & Fatigue Resistance: Achieves a tensile strength up to 130 MPa, flexural modulus up to 10,500 MPa, and excellent Izod impact strength
. It handles high centrifugal forces without fatigue cracking or creep deformation . Precision Dimensional Stability (0.2%–0.6% Shrinkage): Featuring a density range of 1.22–1.35 g/cm³ and a stable molding shrinkage rate of 0.2%–0.6%, the compound maintains precise component dimensions and uniform assembly gaps to prevent airflow attenuation over time
. Heat Resistance & RoHS Compliance: Maintains a Heat Deflection Temperature (HDT) of 102–103°C, ensuring full resistance to elevated heating temperatures while meeting global RoHS environmental compliance standards
. 5% Yield Increase in Injection Molding: Manufactured under MES digital tracking, batch-to-batch property consistency boosts finished component molding yields by approximately 5%, reducing scrap costs
