|
Omega -SPHERES W300 is specified through a very high thermal and mechanical stability.
|
|
|
Advantages:
- density reduction and therefore weight reduction in final products
- reduced binder content. This leads to cost reduction
- Improvement of mechanical properties of the final product like impact strength
- Increase in thermo-shock resistant and dimension stability
- increase in thermal insulation properties
- improvement in rheology and therefore easier application of the final product
- Omega -SPHERES W300 are inflammable, chemical inert and temperature resistant up to 1600°C
| Application areas:
Ceramic microspheres are used in a variety of final application like exterior insulation full systems, IEFS, sparkles, mortars, self-levelling floor compounds, BMC, SMC, brake linings, fire resistant products, covering mould castings, anti-noising compounds, underbody car protection, and PVC plastic soles. Base formulations for many applications can be send.
