SPHERON is a Polish own-brand manufacturer of aluminosilicate microspheres operating through contract manufacturing. We offer A- and E-series grades in 0–150, 0–300, 0–500, 150–300 and 300–500 µm for construction, paints, coatings and composites. Products are made to SPHERON specifications and covered by batch quality control.
Hollow ceramic spheres designed to reduce weight and improve thermal performance.
Cenospheres are lightweight, hollow ceramic particles formed from aluminosilicate material. Their spherical geometry helps manufacturers lower density, improve flow and engineer better thermal and dimensional performance.
Standard product grades
A broad 0–500 µm E-series grade for industrial formulations requiring a light grey to grey microsphere profile.
A versatile 0–300 µm E-series grade balancing controlled particle size with industrial processing flexibility.
A controlled 63–200 µm E-series grade with a concentrated fine-to-medium particle-size distribution for coatings and composites.
A fine 0–150 µm E-series grade for formulations where a smaller maximum particle size is required.
A versatile 0–300 µm A-series grade with a white to light grey color profile.
A fine 0–150 µm A-series grade for formulations requiring a smaller maximum particle size and lighter color.
A broad 0–500 µm A-series grade for large-scale industrial formulations and construction materials.
A controlled 150–300 µm A-series cut for formulations requiring a defined medium particle-size window.
A controlled 150–300 µm E-series cut with a defined medium particle-size window.
A controlled coarse 300–500 µm A-series cut with a white to light grey color profile.
A controlled coarse 300–500 µm E-series cut for formulations requiring larger microspheres.
The microspheres are contract-manufactured for SPHERON at a partner facility in Kazakhstan. We define the specifications, control batch quality and supply the material in SPHERON-branded bulk bags.
The material is manufactured by a production partner according to SPHERON specifications.
Every batch is checked against the agreed parameters and product conformity requirements.
The finished product is packed in SPHERON-branded bulk bags and prepared for shipment.
