Product Name:Cenospheres
English Name:Cenospheres
Aliases:Zeeospheres, Hollow microspheres
Physical Properties:Gray-white or gray loose spherical powder, mainly composed of SiO2 and Al2O3, with a particle size of 2-12 μm and a wall thickness of 8-10% of the diameter. Bulk density 1.6-1.8 g/cm³, refractoriness 1200-1750°C, dielectric constant 2.3-2.4, volume resistivity 1.5×10^10 Ω·cm, thermal conductivity 0.12 W/m·K, oil absorption 16-18 g/100g, Mohs hardness 5-7, ablation rate <1%, compressive strength 1000-3000 kg/cm², specific surface area 1.9 m²/g (3 μm), light diffuse reflectance 80-88%, low water absorption (0.2%).
Uses:Used for modification of engineering plastics (nylon, PP, PBT, PC, POM, etc.) to improve flowability, eliminate glass fiber exposure, overcome warpage, enhance flame retardancy and reduce glass fiber dosage; filled in rigid PVC, PP, PE to produce profiles, pipes and sheets, improving rigidity and heat resistance; filled in PVC, PE cable insulation and sheathing materials to enhance high-temperature resistance, insulation, acid/alkali resistance and processability; filled in epoxy resin copper-clad laminates, unsaturated polyester and silicone resin to lower dielectric constant and water absorption, improve mechanical properties and reduce cost.
