Product Overview
Guangdong Minghao Fiberglass specializes in manufacturing premium Absorbent Glass Mat (AGM) separators engineered specifically for Valve-Regulated Lead-Acid (VRLA) batteries. Utilizing a wet-laid process, our AGM separators possess an ultra-high porosity and exceptional acid absorption capability. They isolate positive and negative plates effectively to prevent internal micro-short circuits while facilitating seamless ionic movement for maximum electrochemical efficiency.

Raw Material & Manufacturing Excellence
100% Microfiber Glass Fiber
Engineered with ultra-fine glass fibers (diameters from 0.5 to 3 μm). Low alkali metal oxide content minimizes electrolyte contamination and self-discharge.
Precision Fiber Grades
Selectable fiber diameter grades including 29°, 34°, 39°, and 44°. Finer fibers enhance absorption and porosity, ensuring stable battery chemistry.
Advanced Wet-Laid Process
Produced via continuous wet-laid forming, vacuum dewatering, and controlled thermal drying to ensure uniform thickness and consistent pore size distribution.
Target Applications
Automotive & Start-Stop
Designed for automotive SLI and advanced Start-Stop systems requiring rapid power response and vibration resistance.
Telecommunications & UPS
Ensures high float-life reliability and backup stability for telecom base stations, data centers, and critical power infrastructure.
Renewable Energy Storage
Ideal for solar, wind, and off-grid energy storage batteries requiring deep cycling resilience and long-term operating life.
Strict Quality Assurance & Factory Capabilities
With an annual production capacity of 10,000 tons, our Renhua manufacturing plant follows strict ISO 9001, ISO 14001, and ISO 45001 standards. Every production batch undergoes comprehensive laboratory testing—including fiber diameter inspection, basis weight, porosity, pore size, water/acid absorption, and tensile strength—guaranteeing 100% compliance with international standards.
