Many applications, one portfolio

Omya offers a unique portfolio of lightweight fillers (LWF) to the construction industry. Omyasphere is a complete solution portfolio based on closed-cell expanded perlite and hollow glass microspheres.

 

You can choose from:

Omyasphere 200 closed-cell expanded perlite;

Omyasphere 400 higher resistance closed-cell expanded perlite;

Omyasphere 900 hollow glass microspheres.

Thinking of volume instead of weight

When replacing ‘heavier’ minerals, such as mineral fillers or aggregates, with Omyasphere LWF the weight of the final product is reduced. The resulting product is easier to use and has advantages from a health and safety perspective.

 

At the same weight, introducing lightweight fillers increases the yield or spread rate, giving a greater coverage area, lowering the costs/m².

Doing more with less

Omyasphere functionality facilitates application with improved workability, sag resistance and easier sandability.

 

Improved comfort properties, such as enhanced thermal insulation, leads to energy savings. Lightweighting products means transportation savings and related CO₂ reduction.

Benefits of Omyasphere

  • Weight reduction – transportation savings
  • Thermal insulation – translates to energy savings
  • Carbon footprint reduction – lowering environmental impact
  • Higher yield – lowering cost/m2
  • Workability & sandability – improving application ease
  • Dimensional stability – improved product rheology and sag & slip

 

Lower the density of your final product

The low density of the Omyasphere LWF portfolio offers lightweighting benefits and results in lower cost in use. The weight of the final products can be reduced by up to 40%, supporting health and safety compliance for workers using and transporting them. The significant density reduction also improves properties and allows faster application rates.

The sustainable contribution of Omyasphere

Omyasphere is ideal to support carbon footprint reduction. Omyasphere also helps reduce thermal conductivity and related energy consumption, for improved well-being and resource consumption reduction. Lower weight also means CO₂ emissions reduction during transportation of the end products.

A more sustainable residential cooling system

Demand for residential cooling is expected to increase significantly because of global warming. Highly reflective roof coatings reduce heat transmission from exterior to interior, thanks to reduced thermal conductivity and to an enhanced solar reflectivity index.

 

Omyasphere is an ideal solution for the sustainable formulation of other paints and coatings applications, like thermal comfort paints, high build façade paints, external wall insulation systems and many others.
