We offer standard packaging in cartons and ton bags, with dimensions varying by product model and density. Customers can discuss custom packaging requirements with our team.
Founded in 2011 with backing from government research institutions, Hainuo Technology has achieved significant breakthroughs in glass microsphere technology. We've been recognized as a "High-Tech Enterprise" and "Outstanding Enterprise in Shanxi province," with our products used in major national projects by CNPC and CNOOC.
Unpackage in well-ventilated areas with minimal vibration to reduce dust emission. Those with dust allergies should use protective eyewear and gloves. Store packages in dry, cool areas away from direct sunlight and keep tightly sealed.
HN20 Glass Microspheres enhance thermal insulation, improve fluidity and stiffness, increase strength endurance, and provide excellent chemical resistance while reducing material weight.
These microspheres have wide applications in aerospace, rubber, plastic, marine, and construction industries as lightweight fillers that improve product performance while reducing costs.
Our products typically range from 10-115µm in size with densities between 0.11-0.606 g/cm³, varying by specific application requirements.
Yes, made from natural sand, our glass microspheres are recyclable and environmentally safe. We maintain strict environmental standards throughout production.
Yes, these microspheres can be added to 3D printing materials to reduce weight, improve strength, enhance printability, and minimize warping.
Absolutely. When used as lightweight aggregate in concrete, they reduce weight while improving thermal insulation, fire resistance, workability and durability.
Current capacity is 15,000 tonnes annually, expanding to over 35,000 tonnes by 2026 with our second production line.
