The automotive radiator water chamber (end tank) is a critical core component of vehicle thermal management systems
To satisfy stringent automotive OEM standards, Qingdao Zhongxin Huamei Plastic Co., Ltd. provides specialized hydrolysis-resistant Glass Fiber Reinforced Nylon (PA6/PA66) compound tailored specifically for injection molding automobile radiator water tanks
Key Mechanical, Thermal & Hydrolysis Advantages for Radiator Chambers
Our engineered glass fiber reinforced polyamide material combines structural rigidity, thermal stability, and light-weighting benefits to replace traditional metal radiator components
[Engine Bay High Heat & Coolant Pressure] ➔ [Glass Fiber Reinforced Nylon Matrix] ➔ [Zero Distortion (HDT 180–250°C)] ➔ [Leak-Proof & Hydrolysis-Resistant Seal]
Extreme Heat & Thermal Cycling Stability: Modified with prime glass fiber reinforcement, the compound maintains a Heat Deflection Temperature (HDT) of 180°C–250°C
. It withstands continuous under-hood thermal pressure and rapid hot-cold cycles without softening or warping . High Structural Rigidity & Impact Defense: Achieves a tensile strength up to 200 MPa, flexural strength of 270 MPa, and notch impact strength of 20 kJ/m²
. It handles high internal coolant circulation pressure and continuous road impacts without fracturing . Hydrolysis Resistance & 30% Weight Reduction: Formulated with an anti-hydrolysis and heat-oxygen aging package, it resists long-term hot glycol exposure without dimensional drift
. Replacing heavy brass or aluminum end tanks cuts component weight by approximately 30%, boosting fuel efficiency and EV range . Simplified Integrated Injection Molding: Excellent melt flow enables one-step precision injection molding of complex geometric snaps, internal baffles, and pipe connectors—drastically reducing secondary assembly costs and boosting production yield
