What safety precautions should be taken when handling HN20 Glass Microspheres?
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.
What are the primary advantages of using hollow glass bubbles?
HN20 Glass Microspheres 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?
These microspheres have wide applications in aerospace, rubber, plastic, marine, and construction industries as lightweight fillers that improve product performance while reducing costs.
What is the size and density range of your glass bubbles?
Our products typically range from 10-115µm in size with densities between 0.11-0.606 g/cm³, varying by specific application requirements.
Are hollow glass bubbles environmentally friendly?
Yes, made from natural sand, our glass microspheres are recyclable and environmentally safe. We maintain strict environmental standards throughout production.
Can HN20 be used in 3D printing applications?
Yes, these microspheres can be added to 3D printing materials to reduce weight, improve strength, enhance printability, and minimize warping.
Are hollow glass bubbles suitable for concrete applications?
Absolutely. When used as lightweight aggregate in concrete, they reduce weight while improving thermal insulation, fire resistance, workability and durability.
What is your annual production capacity?
Current capacity is 15,000 tonnes annually, expanding to over 35,000 tonnes by 2026 with our second production line.
