We provide hollow glass microspheres with complete specifications, stable quality, and superior performance, along with customized production solutions. Our commitment to quality, service, and cost-effectiveness has earned us the long-term trust of domestic and international customers.

• Ultra-lightweight: Density only 0.13-0.80 g/cm³, maximum weight reduction up to 20-30%
• High strength: Maximum pressure resistance is 30,000 psi
• Excellent heat insulation: Hollow and sealed structure, low thermal conductivity, outstanding insulation/cold preservation/fire prevention effects
• Excellent fluidity: Perfectly spherical shape, easy to disperse, reduce viscosity and easy to process
• Chemical stability: Inert, resistant to acids and alkalis, oil-resistant, non-absorbent, non-corrosive
• Low oil absorption rate: Saves resin/adhesive, reduces formulation cost
• Dimensional stability: Reduces shrinkage, warping, cracking and improves product precision
• Electric insulation / low dielectric: Suitable for 5G, PCB, high-frequency communication materials
• Environmentally friendly and non-toxic: Inorganic material, no VOC, complies with export environmental protection requirements
