We offer carton and ton bag packaging options with dimensions varying by model and density. Customers can specify preferred packaging when ordering. Custom packaging solutions are available upon request.
Founded in 2011 with research backing from government institutions, Hainuo Technology has achieved significant technological breakthroughs. We've been recognized as a "High-Tech Enterprise" and "Outstanding Enterprise in Shanxi province," with products used in major national projects by CNPC and CNOOC.
Unpackage in well-ventilated areas with minimal vibration to reduce dust. Those with dust allergies should wear protective eyewear and gloves. Keep packages sealed when not in use.
HGBs enhance thermal insulation, improve fluidity and stiffness, increase strength endurance, and provide chemical resistance while reducing material weight.
Current annual capacity is 15,000 tonnes, expanding to 35,000 tonnes by 2026 with our second production line.
Store in dry, cool areas away from direct sunlight. Keep packages tightly sealed to prevent particle emission.
