We offer carton and ton bag packaging options with dimensions varying by model and density. Customers can contact our team to discuss custom packaging solutions.
Founded in 2011 with government-backed research, Hainuo Technology has achieved significant breakthroughs and been recognized as a "High-Tech Enterprise" and "Outstanding Enterprise in Shanxi province." Our products are used in major national projects by CNPC and CNOOC.
Unpackage in ventilated areas with minimal vibration. Use protective gear (gloves, eyewear) if dust-sensitive. Keep packages sealed when not in use.
They enhance thermal insulation, fluidity, stiffness, strength endurance, and chemical resistance while reducing weight.
Widely used in aerospace, rubber, plastic, marine, and construction industries as lightweight fillers that improve performance and reduce costs.
Density ranges from 0.11-0.606 g/cm³ with sizes from 10-115µm, varying by application.
Yes, made from natural sand, recyclable, and produced with environmental responsibility throughout our processes.
Yes, they reduce weight and improve strength in 3D printing materials while enhancing printability and reducing warping.
Yes, as lightweight aggregate they improve thermal insulation, fire resistance, workability, and durability of concrete.
Currently 15,000 tonnes annually, expanding to over 35,000 tonnes by 2026 with our second production line.
Store in cool, dry, dark areas away from moisture and sunlight. Keep packages tightly sealed to prevent particle emission.
