What safety precautions should be taken when handling HN40 glass bubbles?
Work in ventilated areas, minimize dust generation during unpacking, and use protective gear (gloves, eyewear) if sensitive to fine particles.
What are the primary benefits of using hollow glass bubbles?
They provide excellent thermal insulation, improve material stiffness and fluidity, enhance chemical resistance, and reduce product weight.
What industries commonly use hollow glass bubbles?
Aerospace, marine, construction, plastics, and rubber industries utilize them as lightweight fillers to improve performance and reduce costs.
What is the size and density range of Hainuo glass bubbles?
Our products range from 10-115µm in size with densities between 0.11-0.606 g/cm³, depending on application requirements.
Are hollow glass bubbles environmentally friendly?
Yes, made from natural sand, they're fully recyclable and cause no environmental harm throughout their lifecycle.
Can HN40 glass bubbles be used in 3D printing?
Absolutely. They reduce material weight, minimize warping, and improve printability when added to polymers and resins.
Are these microspheres suitable for concrete applications?
Yes, they serve as lightweight aggregates that enhance thermal insulation, fire resistance, and durability in concrete mixtures.
What is Hainuo's production capacity?
Current annual capacity is 15,000 tonnes, expanding to 35,000 tonnes by 2026 with new production facilities.
How should HN40 glass bubbles be stored?
Store in cool, dry areas away from direct sunlight. Keep packages tightly sealed to prevent moisture absorption and particle emission.
