Hollow glass microspheres are truly a marvel of modern material science. These cutting-edge, multifunctional fill materials stand out with their ultra-fine, hollow spherical shapes, promising unparalleled utility and performance across diverse applications.
Enveloped in alluring shades of gray white or light gray, these microspheres are masterfully crafted from silicon dioxide and alumina. With a bulk density tailored for efficiency,
they range from an impressive 0.9-1.2 grams per cubic centimeter and possess a true density of 1.7 grams per cubic centimeter. The particle sizes show a wide variation,
spanning from 44-2.6 microns, and are available in a versatile array of mesh sizes: 325, 500, 800, 1250, 2500, and 5000. Each microsphere exhibits extraordinary sphericity, exceeding 95%, ensuring precision and reliability.
The robust outer shell of these microspheres encases inert gases such as nitrogen dioxide and carbon dioxide, providing exceptional high-pressure resistance, ranging from 4000-7000 MPa,
and showcasing extraordinary wear resistance. These microspheres can withstand temperatures beyond 1450 degrees, and their superior chemical stability offers resilience against
common acidic, alkaline, and saline environments. They excel in providing outstanding sound and thermal insulation properties, characterized by a conductivity coefficient
of 0.10-0.12, positioning them as a premier choice for a multitude of advanced applications.
Tailored customization of special particle sizes is also available to precisely meet specific client needs.

These hollow glass microspheres exhibit remarkable compressive strength, offering the following impressive functionalities when integrated into composite materials:
They present an array of exceptional features and benefits that are transformative:
1: Enhanced durability and performance: Unlike conventional fillers that may leave behind softer or irregular particles, hollow glass microspheres stand out with their superior fineness,
dramatically enhancing scratch resistance and minimizing friction, thereby elevating the material's overall performance to new heights.
2: Cost Efficiency: Known for their minimal oil absorption rate of just 15-18%, a fraction compared to talc powder or calcium carbonate,
these microspheres as fillers maintain material toughness even at up to 70% addition, without significantly altering the material's integrity.
Their excellent flowability allows for seamless formation in compact molds without the need for heating or pressure,
streamlining manufacturing processes and significantly reducing production costs.
