Cenospheres Marketing Limited offers four calibrated fractions of hollow aluminosilicate microspheres: 100 µm, 160 µm, 300 µm and 500 µm. Each fraction is produced from coal‑derived fly ash and exhibits a composition of SiO₂ 55‑65 %, Al₂O₃ 28‑36 % and Fe₂O₃ 1‑5 %. The supplier markets them as bulk mineral additives for high‑performance composites.
These microspheres typically have an apparent density between 0.35 and 0.7 g/cm³, which enables significant weight reduction in cementitious mixes and polymer matrices. Their thermal conductivity is generally ≤0.10 W/(m·K) and crushing strength ranges from 1.5 to 4 MPa, aligning with industry standards for lightweight fillers. Standard packaging is provided in 1‑ton bulk bags or 25 kg sacks to facilitate handling at large scale.
Key customers are manufacturers of lightweight concrete, automotive‑grade plastics and aerospace‑grade composites that require precise particle size control. The supplier mentions flexible bulk‑order options and offers FOB shipping, while payment and lead‑time details are to be negotiated per order. Importers are advised to request a sample batch and verify any applicable quality certifications before committing to volume purchases.

Cenospheres Marketing Limited, located at 75 Lancaster Roads in London, United Kingdom, presents itself as a bulk supplier of hollow ceramic microspheres. Its harbour‑level trust tier reflects a verified business profile within the marketplace.
While the supplier lists precise size fractions for its microspheres, the announcement does not include MOQ, lead‑time or certification information, so purchasers need to obtain those specifics from the seller. The response statistics indicate no recent replies to enquiries, which may affect communication speed. The company’s current offering is limited to the four cenospheres fractions described.
Cenospheres are hollow aluminosilicate microspheres recovered from coal fly ash, supplied in precise fractions of 100um, 160um, 300um and 500um for industrial applications. These lightweight ceramic spheres serve as functional fillers in cement, concrete, drilling fluids, plastics, rubber and coatings, improving thermal insulation, reducing weight and lowering material costs. Widely traded internationally for import and export, cenospheres are classified as an industrial mineral additive and are typically packaged in big bags or 25kg sacks for bulk shipment.

When ordering, confirm that the selected size fraction - 100 µm, 160 µm, 300 µm or 500 µm - aligns with the target particle size distribution of your product and ask for a recent analysis report confirming the fraction purity. Request a certificate of analysis that details apparent density, chemical composition and moisture content, as these figures influence the behaviour of the microspheres in cement or polymer matrices. Verify that the microspheres meet any applicable industry standards for aluminosilicate fillers in your market.
