We offer standard packaging in cartons and ton bags, with dimensions varying by model and density. For specialized packaging requirements, please contact our team to discuss custom solutions.
Founded in 2011 with research backing from government institutions, Hainuo Technology has achieved significant technological breakthroughs in glass bubble manufacturing. 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. For individuals with dust allergies, we recommend using safety glasses and gloves during handling.
HN20 glass bubbles enhance thermal insulation, improve fluidity and stiffness, increase strength endurance, and provide excellent chemical resistance while reducing material weight.
Our microspheres are widely used in aerospace, rubber, plastic, marine, and construction industries as lightweight fillers that improve product performance while reducing production costs.
Store in cool, dry areas away from direct sunlight. Keep packages tightly sealed to prevent particle emission and protect from moisture.
