Frequently Asked Questions
What packaging options are available for Hainuo HGBs?
We offer standard packaging in cartons and ton bags, with dimensions varying by product model and density. Custom packaging solutions are available upon request through our technical team.
What are Hainuo Technology's achievements in the HGB field?
Founded in 2011 with government-backed research, Hainuo has achieved significant technological breakthroughs and earned recognition including "High-Tech Enterprise" and "Outstanding Enterprise in Shanxi Province." Our products are used in major national projects by CNPC and CNOOC.
What safety precautions should be taken when handling HGBs?
Handle packages in well-ventilated areas, minimize dust generation during unpacking, and use protective equipment (gloves, safety glasses) if sensitive to dust. Store in cool, dry conditions away from direct sunlight.
What are the primary benefits of hollow glass bubbles?
HGBs enhance thermal insulation, improve fluidity and stiffness, increase strength endurance, and provide excellent chemical resistance while reducing material weight.
What industries commonly use hollow glass bubbles?
HGBs are widely used in aerospace, rubber, plastic, marine, and construction industries as lightweight fillers that improve performance while reducing production costs.
What is the size and density range of Hainuo HGBs?
Standard products range from 10-115µm in size with densities between 0.11-0.606 g/cm³, with custom specifications available.
Are HGBs environmentally friendly?
Yes, made from natural sand, HGBs are fully recyclable and cause no environmental harm. Sustainability is central to our production philosophy.
Can HGBs be used in 3D printing applications?
Absolutely. HGBs can be incorporated into 3D printing materials to reduce weight, improve strength, enhance printability, and minimize warping.
Are HGBs suitable for concrete applications?
Yes, as lightweight aggregates they reduce concrete weight while improving thermal insulation, fire resistance, workability, and durability.
What is Hainuo's production capacity?
Current annual capacity is 15,000 tonnes, expanding to 35,000 tonnes by 2026 with our second production line.
What are the storage requirements for HGBs?
Store in dry, cool areas away from moisture and direct sunlight. Keep packages tightly sealed to prevent particle release.
