SEPPE CENOSPHERE
2621900090
SEPPE supplies cenospheres primarily as dry, classified powders, with two core application-oriented grades: oilfield cementing grade and coating grade. Both use lightweight hollow aluminosilicate microspheres, while particle-size control, density requirements, chemical limits, and quality testing are adjusted for each downstream application.
▸ Cenospheres are naturally formed hollow ceramic microspheres recovered and purified from fly ash. Each sphere has a rigid aluminosilicate shell and a sealed hollow interior, creating low density, thermal insulation, and mineral stability in one particle.
▸ SEPPE’s core commercial supply forms are dry oilfield cementing grade and dry coating grade cenospheres. Other particle-size cuts and application-specific controls can be confirmed by purchase specification.
▸ This page provides an integrated overview of both core grades, including applications, physical properties, quality-control parameters, technical documents, packaging, and related resources.
